| root.call {xps} | R Documentation |
Create class CallTreeSet accessing ROOT detection call file.
root.call(xps.scheme, rootfile = character(0), treetype = character(0), treenames = "*")
xps.scheme |
A SchemeTreeSet containing the correct scheme for the ROOT data file. |
rootfile |
name of ROOT data file, including full path. |
treetype |
tree type. |
treenames |
optional character vector of tree names to get only subset of trees. |
An S4 class CallTreeSet will be created, serving as R wrapper to the
existing ROOT detection call file rootfile.
Parameter treetype must be supplied to identify the ROOT trees for slots data
and detcall. Valid tree types are listed in validTreetype.
To get the names of all trees with their extensions treetype, which are stored in
rootfile, you can call function getTreeNames first.
If the CallTreeSet should only handle a subset of the trees stored in
rootfile, the tree names must be supplied as vector treenames.
A CallTreeSet object.

## first, load ROOT scheme file and ROOT data file
scheme.test3 <- root.scheme(paste(.path.package("xps"),"schemes/SchemeTest3.root",sep="/"))
data.test3 <- root.data(scheme.test3, paste(.path.package("xps"),"rootdata/DataTest3_cel.root",sep="/"))
## MAS5 detection call
detcall.mas5 <- mas5.call(data.test3,"tmp_Test3CallAll",tmpdir="",verbose=FALSE)
## use subset of trees
sub.call <- root.call(scheme.test3, "tmp_Test3CallAll.root", "dc5", c("TestA2", "TestB1"))
