Subject: [R] Removing values from a string
So I have the following data frame and I want to know how I can remove all
"NA" values from each string, and also
remove all "|" values from the START of the string. So they should
something like "auto|insurance" or "auto|insurance|quote"
one = data.frame(keyword=c("|auto", "NA|auto|insurance|quote",
"NA|auto|insurance",
? ? ? ? ? ? ? ? ? ? ? ? ? "NA|insurance", "NA|auto|insurance", "<NA>"))
one
Can anyone point me in the right direction? I'm still not too familiar with
regex or gsub to find a solution, and there doesn't seem
to be anything helpful in the stringr package for this task.
Thanks
