For this gsub function below I understand how it works, it is just replacing the $ with nothing. But I haven’t found a clear explanation of what this double escape character (**\ **) means in R and what is it doing here. why is it here and why is there 2 of them. Can someone help please.
mutate(price=gsub(‘\$’,‘’,price)) ← Note: when publish this post it deletes one of the \ for some reason on this webpage. It should be 2 back slashes
