I have string as follows:"v:\work\gene"
however, i can not write this as character string in R
what i did is:
path<- as.character("v:\work\gene")
but it seems that \ is eliminated:
Warning messages:
1: '\w' is an unrecognized escape in a character string
2: '\g' is an unrecognized escape in a character string
3: unrecognized escapes removed from "v:\work\gene"
> path
[1] "v:workgene"
how can i keep the \ in string.
thanks

Please see the FAQ on R for Windows2.16 where the distinction between the standard file separator "/" and the usual Windows file separator "\" is discussed.

Hi weix1, Try either "v:\\work\\gene" or "v:/work/gene". For more information see "Basic Regular Expressions" under ?regex as well as the Windows FAQ.
