Hi,
thanks for you suggestion.
I finally solved it in a different way using apply and is.na for
TRUE NA's
and if(as.character(x) == "NA") etc.
However, I just spotted that read.xls seems to have problems reading
in
special characters such as < or >.
Or could it be that you have problems in not reading the help pages
carefully?
