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.
Works for me:
orientation <- pi
start <- 100000
end <- start+1
names <- letters[1:3]
cat( paste( paste(orientation, as.integer(start), as.integer(end),
names,"\n"), paste(as.integer(start), as.integer(end),"exon\n"), sep=""))
3.14159265358979 100000 100001 a
100000 100001 exon
3.14159265358979 100000 100001 b
100000 100001 exon
3.14159265358979 100000 100001 c
100000 100001 exon
whereas without the as.integer I do get 1e+05.
Setting scipen in options did the job.
Cheers,

Well, you have to convert an integer to character to see it: `as is' is in
your case 64 0's and 1's.
I very much suspect that you have a double and not an integer:
100000
[1] 1e+05
as.integer(100000)
[1] 100000
so that is one answer: actually use an `integer vector' as you claim.
A second answer is in ?options, see `scipen'.
A third answer is to use sprintf() or formatC() to handle the conversion
yourself.

Hi,
I am using the following command to print to a file (I omitted the file
details):
cat( paste( paste(orientation, start, end, names,"\n"), paste(start, end,
"exon\n"), sep=""))
where "orientation" and "names" are character vectors and "start" and
"end" are integer vectors.
The problem is that R coerce the integer vectors to characters. In
general, that works fine, but when one of the integer is 100000 (or has
more 0's) then R prints it as 1e+05. This behavior causes a lot of
trouble for the program reading R's output.
This problem occur with paste, cat,
and print (i.e. paste(100000)="1e+05" and so on).
I tried to change the "digit" option in "options()" but that did not help.
Is is possible to change the behavior of the coercing or are there any
work arounds?
