simulateAndTable: simulate and table information in one step

In adibender/rFtools: Tools for the analysis of Random Forests (and cforest)

Description

A wrapper that performs tabulation of the CategoryFrequencies-objects directly instead of saving them to the hard drive first as in simulateAndSafe.

Usage

simulateAndTable(seed = 123, n.obs = 500, n.snp = 200, 
maf = rep(c(0.05, 0.1, 0.25, 0.4), each = 50), ntree = 500, 
mafIntervals = list(maf0.05 = 1:50, maf0.10 = 51:100, 
maf0.25 = 101:150, maf0.40 = 151:200))

Arguments

seed	The seed to be used in data simulation.
n.obs	A integer. The number of observations.
n.snp	A integer. The number of SNPs.
maf	A numeric of length n.snps indicating the MAF with which the according SNP should be simulated.
ntree	Passed to randomForest.
mafIntervals	A list with each element giving the indices of variables being simulated with the according MAF. Depends on how the data was simulated in simulateSNPdata.

Value

A list with components:

tableAll	An object of class LevelsVsLayerByMAF as returned by tableLevelsVsLayerByMAF.
tableSplitVars	An object of class SplitVarLevelsVsLayerByMAF as returned by tableSplitVarLevelsVsLayerByMAF.
tableCforest	An object of class LevelsVsLayerCFbyMAF as returned by tableLevelsVsLayerCFbyMAF.
