R 3.1.1 OS X (and Windows)Colleagues I have some code that manages files. Previously (as late as 3.1.0), the command: file.info(FILENAME)$mtime == “” yielded T/F Now, it triggers an error: Error in as.POSIXlt.character(x, tz, ...) : character string is not in a standard unambiguous format I looked through Peter Dalgaard’s list of changes in 3.1.1 and I cannot find anything that would explain the change between versions. I have fixed the problem. However, I am concerned that other problems may be lurking (i.e., the changes might affect other commands). Of note, I ran: str(file.info(FILENAME)$mtime) in both versions of R and the results did not differ Can anyone explain what changed so that I can search my code efficiently?
Can you explain how that managed to give TRUE (sic)? It was always a POSIXct timestamp, and as such is never equal "" (assuming that your mail client mangled ASCII double quotes).
I believe the relevant report is https://bugs.r-project.org/bugzilla/show_bug.cgi?id=15829
