gsub: Removing a special character at the end of a string in R

Question

I am looking to replace all *s at the end of a string, in R.

txt <- c("arm","foot-ha-*","lefroo", "bafoobar*")
gsub("/\\*$/","",txt, perl=TRUE); 

I would like to convert txt to be "arm" "foo-ha-" "lefroo" "bafoobar"

What am I doing wrong?

Thanks!

您在正则表达式中不需要/ 。

gsub("\\\\*$", "", txt)
