I believe the backslash is not considered an escape character by the extended RE library used by R (perl=FALSE), so it is being treated as a literal. This means that the last ] is outside the character class and is the atom that the * applies to. gsub(^([[:alnum:]\\[\\]]*).*, \\1, a]]]rray[n]

You are chasing your tail. You have already achieved your goal, but you don't seem to understand that. The three characters C:\ are represented in R as C:\\ so when you see the latter, the former is what is actually already in memory. C:\ is not legal R code (it is an unterminated string).

Re: [R] gsub() issue...

The backslashes in the patt argument need to be doubled since \ is a special regex character. Or it may work to set fixed =TRUE. Either: original - INFILTRATION INF_BASE \\n AIRCHANGE=1 replace - INFILTRATION INF_BASE \n AIRCHANGE=3 new_texte - gsub(patt=original,replace,text) Or:

[R] gsub,regex and replacing

Dear group, I need to modify some characters in a data frame. I want to use gsub and the regex functionalities to do this. Here is the data frame (df): DESCRIPTIONprix quantity 1 CORN Jul/10-1.50 2 CORN May/10 -1082.0

Next time you include a data frame that has spaces in the fields, please consider using 'dput' to provided the data. It is hard to read in otherwise. Will this do it: x - read.table(textConnection( DESCRIPTIONprix quantity + 1 'CORN Jul/10'-1.5
