void setArgStatus(const RooArgSet& set, Bool_t active)
void cacheArgs(RooArgSet& varSet, const RooArgSet* nset = 0)
 Cache given RooAbsArgs with this tree: The tree is
 given direct write access of the args internal cache
 the args values is pre-calculated for all data points
 in this data collection. Upon a get() call, the
 internal cache of 'newVar' will be loaded with the
 precalculated value and it's dirty flag will be cleared.
const RooArgSet* get(Int_t index) const
 Load the n-th data point (n='index') in memory
 and return a pointer to the internal RooArgSet
 holding its coordinates.
RooAbsArg* addColumn(RooAbsArg& var)
 Add a new column to the data set which holds the pre-calculated values
 of 'newVar'. This operation is only meaningful if 'newVar' is a derived
 value.

 The return value points to the added element holding 'newVar's value
 in the data collection. The element is always the corresponding fundamental
 type of 'newVar' (e.g. a RooRealVar if 'newVar' is a RooFormulaVar)

 Note: This function is explicitly NOT intended as a speed optimization
       opportunity for the user. Components of complex PDFs that can be
       precalculated with the dataset are automatically identified as such
       and will be precalculated when fitting to a dataset

       By forcibly precalculating functions with non-trivial Jacobians,
       or functions of multiple variables occurring in the data set,
       using addColumn(), you may alter the outcome of the fit.

       Only in cases where such a modification of fit behaviour is intentional,
       this function should be used. (E.g collapsing a continuous B0 flavour
       probability into a 2-state B0/B0bar category)
RooArgSet* addColumns(const RooArgList& varList)
TList* split(const RooAbsCategory& splitCat) const
 Sanity check
RooPlot* plotOn(RooPlot* frame, const RooLinkedList& argList)
 Plot dataset on specified frame. By default an unbinned dataset will use the default binning of
 the target frame. A binned dataset will by default retain its intrinsic binning.

 The following optional named arguments can be used to modify the default behavior

 Data representation options

 Asymmetry(const RooCategory& c) -- Show the asymmetry of the daya in given two-state category [F(+)-F(-)] / [F(+)+F(-)].
                                    Category must have two states with indices -1 and +1 or three states with indeces -1,0 and +1.
 ErrorType(RooAbsData::EType)    -- Select the type of error drawn: Poisson (default) draws asymmetric Poisson
                                    confidence intervals. SumW2 draws symmetric sum-of-weights error
 Binning(double xlo, double xhi, -- Use specified binning to draw dataset
                      int nbins)
 Binning(const RooAbsBinning&)   -- Use specified binning to draw dataset
 Binning(const char* name)       -- Use binning with specified name to draw dataset
 RefreshNorm(Bool_t flag)        -- Force refreshing for PDF normalization information in frame.
                                    If set, any subsequent PDF will normalize to this dataset, even if it is
                                    not the first one added to the frame. By default only the 1st dataset
                                    added to a frame will update the normalization information

 Histogram drawing options

 DrawOption(const char* opt)     -- Select ROOT draw option for resulting TGraph object
 LineStyle(Int_t style)          -- Select line style by ROOT line style code, default is solid
 LineColor(Int_t color)          -- Select line color by ROOT color code, default is black
 LineWidth(Int_t width)          -- Select line with in pixels, default is 3
 MarkerStyle(Int_t style)        -- Select the ROOT marker style, default is 21

 MarkerSize(Double_t size)       -- Select the ROOT marker size
 XErrorSize(Double_t frac)       -- Select size of X error bar as fraction of the bin width, default is 1


 Misc. other options

 Name(const chat* name)          -- Give curve specified name in frame. Useful if curve is to be referenced later
 Invisble(Bool_t flag)           -- Add curve to frame, but do not display. Useful in combination AddTo()
 AddTo(const char* name,         -- Add constructed histogram to already existing histogram with given name and relative weight factors
 double_t wgtSelf, double_t wgtOther)



RooPlot * plotOn(RooPlot *frame, PlotOpt o)
 Create and fill a histogram of the frame's variable and append it to the frame.
 The frame variable must be one of the data sets dimensions.

 The plot range and the number of plot bins is determined by the parameters
 of the plot variable of the frame (RooAbsReal::setPlotRange(), RooAbsReal::setPlotBins())

 The optional cut string expression can be used to select the events to be plotted.
 The cut specification may refer to any variable contained in the data set

 The drawOptions are passed to the TH1::Draw() method
RooPlot* plotAsymOn(RooPlot* frame, const RooAbsCategoryLValue& asymCat, RooTreeData::PlotOpt o) const
 Create and fill a histogram with the asymmetry N[+] - N[-] / ( N[+] + N[-] ),
 where N(+/-) is the number of data points with asymCat=+1 and asymCat=-1
 as function of the frames variable. The asymmetry category 'asymCat' must
 have exactly 2 (or 3) states defined with index values +1,-1 (and 0)

 The plot range and the number of plot bins is determined by the parameters
 of the plot variable of the frame (RooAbsReal::setPlotRange(), RooAbsReal::setPlotBins())

 The optional cut string expression can be used to select the events to be plotted.
 The cut specification may refer to any variable contained in the data set

 The drawOptions are passed to the TH1::Draw() method
TH1 * fillHistogram(TH1* hist, const RooArgList& plotVars, const char* cuts = "", const char* cutRange = 0) const
 Loop over columns of our tree data and fill the input histogram. Returns a pointer to the
 input histogram, or zero in case of an error. The input histogram can be any TH1 subclass, and
 therefore of arbitrary dimension. Variables are matched with the (x,y,...) dimensions of the input
 histogram according to the order in which they appear in the input plotVars list.
Roo1DTable* table(const RooAbsCategory& cat, const char* cuts = "", const char* opts = "") const
 Create and fill a 1-dimensional table for given category column
 This functions is the equivalent of plotOn() for category dimensions.

 The optional cut string expression can be used to select the events to be tabulated
 The cut specification may refer to any variable contained in the data set

 The option string is currently not used
Double_t moment(RooRealVar& var, Double_t order, Double_t offset = 0, const char* cutSpec = 0, const char* cutRange = 0) const
 Lookup variable in dataset
RooRealVar* meanVar(RooRealVar& var, const char* cutSpec = 0, const char* cutRange = 0) const
 Create a new variable with appropriate strings. The error is calculated as
 RMS/Sqrt(N) which is generally valid.
RooRealVar* rmsVar(RooRealVar& var, const char* cutSpec = 0, const char* cutRange = 0) const
 Create a new variable with appropriate strings. The error is calculated as
 RMS/(2*Sqrt(N)) which is only valid if the variable has a Gaussian distribution.
Bool_t getRange(RooRealVar& var, Double_t& lowest, Double_t& highest) const
 Lookup variable in dataset
RooPlot* statOn(RooPlot* frame, const RooCmdArg& arg1 = RooCmdArg::none(), const RooCmdArg& arg2 = RooCmdArg::none(), const RooCmdArg& arg3 = RooCmdArg::none(), const RooCmdArg& arg4 = RooCmdArg::none(), const RooCmdArg& arg5 = RooCmdArg::none(), const RooCmdArg& arg6 = RooCmdArg::none(), const RooCmdArg& arg7 = RooCmdArg::none(), const RooCmdArg& arg8 = RooCmdArg::none())
 Add a box with statistics information to the specified frame. By default a box with the
 event count, mean and rms of the plotted variable is added.

 The following optional named arguments are accepted

   What(const char* whatstr)          -- Controls what is printed: "N" = count, "M" is mean, "R" is RMS.
   Format(const char* optStr)         -- Classing [arameter formatting options, provided for backward compatibility
   Format(const char* what,...)       -- Parameter formatting options, details given below
   Label(const chat* label)           -- Add header label to parameter box
   Layout(Double_t xmin,              -- Specify relative position of left,right side of box and top of box. Position of
       Double_t xmax, Double_t ymax)     bottom of box is calculated automatically from number lines in box
   Cut(const char* expression)        -- Apply given cut expression to data when calculating statistics
   CutRange(const char* rangeName)    -- Only consider events within given range when calculating statistics. Multiple
                                         CutRange() argument may be specified to combine ranges

 The Format(const char* what,...) has the following structure

   const char* what          -- Controls what is shown. "N" adds name, "E" adds error,
                                "A" shows asymmetric error, "U" shows unit, "H" hides the value
   FixedPrecision(int n)     -- Controls precision, set fixed number of digits
   AutoPrecision(int n)      -- Controls precision. Number of shown digits is calculated from error
                                + n specified additional digits (1 is sensible default)
   VerbatimName(Bool_t flag) -- Put variable name in a \verb+   + clause.

RooPlot* statOn(RooPlot* frame, const char* what, const char* label = "", Int_t sigDigits = 2, Option_t* options = "NELU", Double_t xmin = 0.15, Double_t xmax = 0.65, Double_t ymax = 0.85, const char* cutSpec = 0, const char* cutRange = 0, const RooCmdArg* formatCmd = 0)
