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?
Lep pozdrav / With regards,
Gregor Gorjanc
