[R] Printing integers in R "as is"

[Firas Swidan]

Hi,

thanks for the suggestions. However, for some reason the first one did not
work. Trying

cat( paste( paste(orientation, as.integer(start), as.integer(end),
names,"\n"), paste(as.integer(start), as.integer(end),"exon\n"), sep=""))

resulted in the same problem.

Setting scipen in options did the job.

Cheers,
Firas.
