Hi Federico,
A forward slash isn't a special character:
> strsplit("T/T", "/")
[[1]]
[1] "T" "T"
so there's some other problem.
Are you sure that your first column contains strings and not factors?
What does str(my.data) tell you?
Does
strsplit(as.character(my.data[1,1]), "/")
work?
If you used read.table() to get your data in, you might want the
as.is=TRUE or the stringsAsFactors=FALSE argument.
