Hi All,
is there a way of using strsplit with a forward slash '/' as the splitting
point?
For data such as:
1 T/T C/C 16/33
2 T/T C/C 33/36
3 T/T C/C 16/34
4 T/T C/C 16/31
5 C/C C/C 28/29
6 T/T C/C 16/34
strsplit(my.data[1,1], "/") # and any variation thereof
Error in strsplit(apoe[1, 1], "/") : non-character argument
It looks as though your my.data[1,1] value is a factor, not a character
value.
strsplit(as.character(my.data[1,1]), "/")
would work, or you could avoid getting factors in the first place, using the
stringsAsFactors argument when you create the dataframe.

Any advice will be gratefully received.
Best wishes,
Federico
