• How to escape backslashes in R string 3 answers

I\'m working in R and having troubles escaping the backslash. I am using the library stringr.

install.packages(\"stringr\", repos=\'http://cran.us.r-project.org\')
library(\"stringr\")

I would like to do str = str_replace_all(str, \"\\\", \"\")

So I tried str = str_replace_all(str, \"\\\\\", \"\") but it won\'t work.

What should I do?

回答1:

I found a solution that works

str = gsub("([\\])","", str)

回答2:

Use Hmisc::escapeRegex and Hmisc::escapeBS which automatically escapes backslashes and other regex special characters.
