Hi, Let's create the xxx object just to avoid confusion even if it's not necessary for reproducing the problem below:
xxx <- 8:3 If I start typing this: max(xxx[ and now try to autocomplete with <TAB>, then I get the following error (and a warning): > max(xxx[Error in grep(sprintf("^%s", makeRegexpSafe(text)), allArgs, value = TRUE) : invalid regular expression '^xxx[' In addition: Warning message: In grep(sprintf("^%s", makeRegexpSafe(text)), allArgs, value = TRUE) : regcomp error: 'Invalid regular expression' Now it seems that this problem in R has managed to screw up something out of R (and this is probably OS dependent, I'm running 64-bit openSUSE 10.3) because when I quit R and try to do something at the shell level, what I type is not echoed anymore in the terminal window. For example if I type 'whoami' followed by <Enter>, here is what I get on the screen (only the output of the command is displayed but not the command itself): [EMAIL PROTECTED]:~> hpages I've tried this with other R versions (2.6.1, 2.6.2) on other Linux flavors (64-bit openSUSE 10.1, 32-bit openSUSE 10.3, 32-bit Ubuntu 6.06) and got almost the same thing, the only difference being that with older versions of R (e.g. with 2.7.0 from 2007-12-09 r43632), I get the error message but no additional warning.
