[R] replace "%" with "\%"

[Liviu Andronic]

Dear all,
I'm trying to gsub() "%" with "\%" with no obvious success.
> temp1 <- c("mean", "sd",   "0%",   "25%",  "50%",  "75%",  "100%")
> temp1
[1] "mean" "sd"   "0%"   "25%"  "50%"  "75%"  "100%"
> gsub("%", "\%", temp1, fixed=TRUE)
[1] "mean" "sd"   "0%"   "25%"  "50%"  "75%"  "100%"
Warning messages:
1: '\%' is an unrecognized escape in a character string
2: unrecognized escape removed from "\%"

I am not quite sure on how to deal with this error message. I tried
the following
> gsub("%", "\\%", temp1, fixed=TRUE)
[1] "mean"   "sd"     "0\\%"   "25\\%"  "50\\%"  "75\\%"  "100\\%"

Could anyone suggest how to obtain output similar to:
[1] "mean"   "sd"     "0\%"   "25\%"  "50\%"  "75\%"  "100\%"

Thank you,
Liviu
