## Get/Set Present Call Values

### Description

Get/set present call values from/for class `CallTreeSet`.

Usage

`presCall(object)`
`presCall(object, treenames = NULL) <- value`
`pvalData(object)`
`pvalData(object, treenames = NULL) <- value`

### Arguments

`object` | object of class `CallTreeSet`.
`treenames` | `character` vector containing optional tree names to be used as subset.
`value` | `data.frame` containing present call values.

### Details

Get the p-values from slot `data` or present calls from slot `detcall`, or set slot `data` or `detcall`, respectively, to `value`.

Method `presCall` returns the present calls from slot `detcall` as `data.frame`, while replacement method `presCall<-` allows to replace slot `detcall` with a `data.frame`.

Method `pvalData` returns the p-values from slot `data` as `data.frame`, while replacement method `pvalData<-` allows to replace slot `data` with a `data.frame`.

In order to create an `CallTreeSet` containing only a subset of e.g. slot `data`, first export slot `data` using method `pvalData`, create a `character` vector containing only `treenames` to be used in the subset, and then use replacement method `pvalData<-` to replace slot `data` with the subset. Slots `treenames` and `numtrees` will be updated automatically for `pvalData<-` but not for `presCall<-`.

Note: When creating `character` vector `treenames` it is sufficient to use the name part of the tree name w/o the extension.

Note: If you do not want to replace your current object, create first a copy of type `CallTreeSet` by simply writing `newobj <- oldobj`, and use `newobj` for replacement.

### Examples

    ## Not run:
    ## 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="/"))

    ## create an CallTreeSet
    call.mas5 <- mas5.call(data.test3,"tmp_TestMAS5Call",tmpdir="",verbose=FALSE)

    ## get p-values
    value <- pvalData(call.mas5)

    ## selected treenames only
    treenames <- c("TestA2", "TestB1")

    ## make a copy of your object if you do not want to replace it
    subset.call <- call.mas5

    ## replace slot data with subset
    exprs(subset.call, treenames) <- value
    str(subset.call)
    ## End(Not run)
