Hello!
Data.frames have new rownames funcionality, however in use of colnames<-
in R-devel "changes" this. Here is the example:
> df1 <- data.frame(letters[1:5])
> attributes(df1)
$names
[1] "letters.1.5."
$row.names
[1] 1 2 3 4 5
$class
[1] "data.frame"
> colnames(df1) <- "bla"
> attributes(df1)
$names
[1] "bla"
$row.names
[1] "1" "2" "3" "4" "5"
$class
[1] "data.frame"
?rownames/colnames help page (R-devel) says that value is coerced to
character, but why are rownames coerced to character if I assign
colnames to a data.frame?
