Hi,
I have uploaded a copy of the file here:
- http://pastebin.com/fd0edfab
the file has also been passed throught the unix command tool unexpand, but
it doesn't solve the problem.
using head=TRUE instead of head=T has also the same effect.
the output of print(names) is:
> print(names(ngly), quote=TRUE)
[1] "snp" "gene"
[3] "chromosome" "distance_from_gene_center"
[5] "position" "ame"
[7] "csasia" "easia"
[9] "eur" "mena"
[11] "oce" "ssafr"
[13] "X" "X.1"
[15] "X.2"
Thank you to all the people who answered me to my mail address, but I
couldn't solve the problem yet.
