Windows usernames are case-insensitive and almost any Unicode character is allowed in a username. The user should be able to login with her username given in any case and not be refused. However, this opens up a security problem in terms of the sshd_config Match rules. The match rules for user and group names have to operate case-insensitive as well, otherwise the user can override her settings

...3"), proto=list(Name="", Number=0)) Error in strcapture("(.+) (.+)", c("One 1", "noSpaceInLine", "Three 3"), : number of matches does not always match ncol(proto) First, isn't the 'number of matches' the number of parenthesized subpatterns in the regular expression? I thought that if the entire pattern matches then the subpatterns without matches would be shown as matches at position 0 with length 0. Hence either the pattern is compatible with the prototype or it isn't, it does not depend on the text input. E.g., > regexe...

Currently sub(perl=TRUE) allows you to specify \U and \L in the replacement argument so that the rest of the subpatterns in the line (the \\<digit> things) will be converted to upper or lower case, respectively. perl also also has a \E operator to end these case conversions for the rest of the subpatterns (so they retain whatever case they had in the original text). For symmetry's sake I think it would be...

The new strcapture function in R-devel is handy, capturing the matches to the parenthesized subpatterns in a regular expression in the columns of a data.frame, whose column names and classes are given by the 'proto' argument. E.g., > p1 <- data.frame(Name="", Number=0) > str(strcapture("([[:alpha:]]*) +([[:digit:]]*)", c("Three 3", "Twenty 20&quo...

...the end of the major ``for'' loop in the function. Although the diff is relative to the 5.1p1 version, I encountered the problem working with the 3.9p1 version; the code is consistent in these versions. The meaning of the additional code is the following: - If a string fails to match the subpattern of the configuration, then execution will flow into ``else'' branch. - Normally, the failure of a match is a failure (``got_positive'' retains its initialized value of zero). - However, where a failure is desired (the ``!'' in the specification subpattern), then the occurr...

Hello everybody, this might be a trivial question, but I have been unable to find this using Google. I am trying to replace double backslashes with single backslashes using gsub. There seems to be some unexpected behaviour with regards to the replacement string "\\". The following example uses the string C:\\ which should be converted to C:\ . > gsub("\\\\",
