I'm relatively new to R, although I've used it to some extent to perform simple tests.
My issue seems minor, as it doesn't seem to affect what I need to do with my data frames, but it bothers me nonetheless :
When I use str() and summary(), gives me :
Class :character Class :character
Mode :character Mode :character
instead of something like
M = x Treatment1 = x1
F = y Treatment2 = y2
'data.frame': 107 obs. of 6 variables:
Gender : chr "M" "M" "F" "F" ... Treatment : chr "A" "A" "B" "E"
Gender : Factor w/ 2 levels "F","M": etc. Treatment : Factor w/ 2 levels "Treatment1", Treatment2... etc.
Any idea why ?
Thanks in advance,
