[BioC] assigning phenoData via assign

[Benilton Carvalho]

Hi everyone,

I'm sorry if this was already discussed, as I did not succeed finding  
anything relevant in the archives.

I'm trying to set the phenoData slot using get() or something  
similar, eg:

library(Biobase)
objName <- "sample.ExpressionSet"
data(list=objName)
pd <- phenoData(get(objName))

get(objName)@phenoData <- pd    ## this will fail

I could copy the object to a temporary one:

tmp <- get(objName)
tmp at phenoData <- pd
assign(objName, tmp)
rm(tmp)

how can I avoid this copy?

thanks a lot,

b
