with the samples have 23 samples, the Prot.amounts
file have 30 different samples and their corresponding values. How do I include
into the loop that I only want to replace those Prot.amount values found in the
NAD dataframe?
Thank you so much!

What I would probably do is along these lines:
iddf <- data.frame(Sample.id=names(Prot.amount), new.id=Prot.amount[1,])
newNAD <- merge( NAD, iddf)
This is not tested, but it looks right to me,
assuming I understand the structure of what
you're trying to do.
I'm also assuming that NAD h
I think this is what you want
NAD$Sample.Id <- t(Prot.amount[NAD$Sample.Id])

Hi,
This is a question of a newbie getting into the exciting world of R.
I have several dataframes in the same format as NAD:
> NAD[1:3,1:3]
Sample.Id Main.abs..1 Main.abs..2
