This is actually the one you want. You may be getting confused by the
fact that print does some formatting of strings, including enclosing
them in quotes. To see what you've actually got here, try out the
cat() function:
x <- "FBpp0070086;FBpp0099643;FBpp0112915"
cat(gsub(";", "\",\"", x))
FBpp0070086","FBpp0099643","FBpp0112915
So that's what you said you wanted, although I expect you also want
quotes at the beginning and end of the vector. I also tend to
alternate " and ' instead of escaping quotes (only works once of
course, but usually that's all you need), so:
cat(paste('"', gsub(";", '",\"', x), '"', sep = ""))
"FBpp0070086","FBpp0099643","FBpp0112915"
Best,
Ista
