gsub difficulty
Any of these will replace every dot with a space:
x <- "a.b.c"
gsub("\\.", " ", x)
gsub("[.]", " ", x)
gsub(".", " ", x, fixed = TRUE)
chartr(".", " ", x)
See ?regex for more info on regular expressions.

Greetings R-ians:
I know what doesn't work but I don't know why, nor how to remedy things.
I have a character string containing "." which I want to replace with " "
gsub(".", " ", file.label) replaces the every character with a blank.
However gsub(".xls", " ", file.label) replaces ".xls" with a blank as
expected.
It appears that "." is some kind of wild-card. How do I tell gsub that a
period is just a period?
Thanks.
