Matching entire string in R

Question

Consider the following string:

string = \"I have #1 file and #11 folders\"

I would like to replace the pattern #1 with the word

Answer 1

I'm not sure if I understood right, but does this help -

a <- "I have #1 file and #11 folders"
b <- "I have #1file and #11 folders"
c <- "I have #1,file and #11 folders"

> gsub(x = a, pattern = "#1.*file", replacement = "one file")
[1] "I have one file and #11 folders"
> gsub(x = b, pattern = "#1.*file", replacement = "one file")
[1] "I have one file and #11 folders"
> gsub(x = c, pattern = "#1.*file", replacement = "one file")
[1] "I have one file and #11 folders"
