I didn't notice that I was emailing the individuals rather than the
list!!!!!!

Briefly, THANKS TO EVERYONE.

Second, I managed to call and display all my sequences like this

sapply(1:dim(A)[1], function(i) paste(A$chr[i],' ',A$start[i],' ',A$end[i],'
tags: ',A$tags[i],' ',getSeq(Mmusculus, as.character(A$chr[i]), A$start[i],
A$end[i])))

As you see, it's made up of ideas from all three respondents. (Michael's
solution actually gave me an idea to solve some other problem not mentioned
here. So, nothing gets wasted.)

Sorry for the off-list emailing issue.

Ivan
