Hi. I am using R 2.5.1 on a Windows XP machine. Here is an example of a piece of code I was running in older versions of R on the same machine. I am looking for underscores and replacing them with periods. This result is from R 2.4.1:
>gsub ( "\\_+","\.","AAA_I") [1] "AAA.I" > Here is what I get in R 2.5.1: >gsub ( "\\_+","\.","AAA_I") [1] "AAA.I" Warning messages: 1: '\.' is an unrecognized escape in a character string 2: unrecognized escape removed from "\." > I still get the same result, which is what I want, but now I get a warning message. Am I actually doing something wrong that the previous versions of R didn't warn me about? Or is this warning message unwarranted? Is there a fully approved method for getting the same functionality?
