obtainsamples: Draw TIC map

In jmbadia/GcxGctools: Tools for GCxGc data

Description

Based on the arguments measures samplestodraw_TIC=NA, samplestodraw_altTIC=NA, samplestodraw_LOGTIC=NA,samplestodraw_LOGaltTIC=NA, this function returns the proper columns of the totalsamples

Usage

obtainsamples(allsamples, samplestodraw_TIC = NA, samplestodraw_altTIC = NA,
  samplestodraw_LOGTIC = NA, samplestodraw_LOGaltTIC = NA)

Arguments

allsamples	all the samples from where to choose the columns asked by the user
samplestodraw_TIC	list of samples whose TIC needs to be drawed. The samples should be referred by their file position on a alphabetical ordered file list. Moreover, it can be drawed the result of adding or substracting a combination of samples; that operation should be indicated with a vector of samples, indicating with a minus the sample that should be substracted. e.g. samplestodraw_TIC=list(1,2,c(1,-3)) draws the TIC of the 1st and second sample, as well as the result of substract the 3rd's TIC sample from the 1st
samplestodraw_altTIC	analogously to the previous argument, list of samples whose "altered" TIC needs to be drawed. "Altered" TIC is refered to a TIC without specific masses (see precook_measures() function). See the samplestodraw_TIC argument for further details.
samplestodraw_LOGTIC	list of samples whose log(TIC) needs to be drawed. e.g. samplestodraw_LOGTIC=list(c(1,-3),2) draws two plots, log(TIC(sample3)-log(TIC(sample1) and log(TIC(sample2).
samplestodraw_LOGaltTIC	analogously to the previous argument, list of samples whose TIC needs to be drawed logarithmically. The only diference is the TIC ploted is the altered one, a TIC without specific masses (see precook_measures() function).

Value

matrix whose columns have been asked from the allsamples

Examples

obtainsamples(allsamples=matrix(1:10,nrow=2),samplestodraw_TIC=list(1,2,c(1,-3)))
