I guess your string value is in a file? And you'd like to update the file
contents. You didn't say which OS you're on. I'm a Linux person, and the
simplest for me would be:
sed -i -r "s/'/\\'/g" myfile.txt #note the \\ becomes a single \ in the
output. weird.
Or just edit the file in your favorite editor. In mine, vim, it would be
the command ":g/'/s/\\'/g" (the command is within the " marks).
You are correct that you could use gsub(). But you can't just paste your
string into an R program as is, as you have already seen. You'd need to put
it into a file. Then read that file into a program (perhaps an R program
using gsub()) to write the updated string to another file. Which contents
you could then cut'n'paste into your original R file.
something like:
#!/usr/bin/Rscript
#
files <- commandArgs(trailingOnly=TRUE);
#
for (infile in files) {
x=readLines(infile);
y=gsub("'","\\\\'",x);
ofile=paste0(infile,".new");
writeLines(y,ofile);
}
