I assume that the problem is the following line:
> data2 <- read.table(paste(path1t, file_wasaux2[i],header=TRUE))
The default separator of paste is " ", see:
?paste
that probably means that the file you want to read has a different name
than what you actually provide as the file name.
Just a guess, though....
Please let me add that it is probably not a good idea to call your data
data. First, it is not very descriptive, meaning: you may have problems
in the future to understand your own code. Second, a function of the
same name exists already.
Hope this helps,
Roland
