Hi,
I noticed that when using print( , right=TRUE) on a character
matrix with no colnames, the col numbers get displayed on the
left of each column:
> m <- matrix(rep(c("XXXXXX", "XXXX"), 6), ncol=3)
> print(m, right=FALSE)
[,1] [,2] [,3]
[1,] "XXXXXX" "XXXXXX" "XXXXXX"
[2,] "XXXX" "XXXX" "XXXX"
[3,] "XXXXXX" "XXXXXX" "XXXXXX"
[4,] "XXXX" "XXXX" "XXXX"
> print(m, right=TRUE)
[,1] [,2] [,3]
[1,] "XXXXXX" "XXXXXX" "XXXXXX"
[2,] "XXXX" "XXXX" "XXXX"
[3,] "XXXXXX" "XXXXXX" "XXXXXX"
[4,] "XXXX" "XXXX" "XXXX"
OTOH if the matrix has colnames, they do get displayed on the
right of each column when 'right=TRUE':
> colnames(m) <- letters[1:3]
> print(m, right=FALSE)
a b c
[1,] "XXXXXX" "XXXXXX" "XXXXXX"
[2,] "XXXX" "XXXX" "XXXX"
[3,] "XXXXXX" "XXXXXX" "XXXXXX"
[4,] "XXXX" "XXXX" "XXXX"
> print(m, right=TRUE)
a b c
[1,] "XXXXXX" "XXXXXX" "XXXXXX"
[2,] "XXXX" "XXXX" "XXXX"
[3,] "XXXXXX" "XXXXXX" "XXXXXX"
[4,] "XXXX" "XXXX" "XXXX"
That looks better!
Shouldn't the same happen for the col numbers when 'right=TRUE'?
Thanks,
H.
