HI!!!
I have a table containing qualitative and quantitative data; one of the
columns contains "Level of education", and the possibilities are "none",
"High school", "college"; I want to give the value 0 to "none", the value 1
to "High school", and 2 to "college", but I got the following error:
In `[<-.factor`(`*tmp*`, educa = "college", value = 2) :
invalid factor level, NAs generated
WHAT IS WRONG????? :S :S :S
THANKS A LOT!!!!!!!!!!!!!!
