[BioC] string to function argument

[Jeremiah H. Savage]

Hello,

I would like to get the Table information out of multiple GPLList objects.

How can I use a string/char variable as a function argument?

In this case the function is GEOquery::Table()

geodata <- parseGEO("GSExxxx.soft")
gpldata <- GPLList(geodata)[1]
gplname <- names(gpldata)  # eg. "GPL96"
gplaccess <- paste(gpldata,gplname,sep="$")

ENTREZ_GENE_ID <- Table(gplaccess)$ENTREZ_GENE_ID
###^^^ the above line does NOT work ,but

ENTREZ_GENE_ID <-Table(gpldata$GPL96)$ENTREZ_GENE_ID
###^^^ the above line DOES work
