Dear R-list,
I currently have to convert a data.frame with several factor-variables to a
numeric matrix.
Now the problem is, that the order of the factor-labels don't match the order I
would like to use.
for example, let's assume I have this factor-variable in my data-frame:
x <- factor(rep(1:4, 5), labels=c("slightly disagree", "disagree", "agree",
"slightly agree"))
Now I would like to convert this to a numeric vector so that disagree == 1,
slightly disagree == 2, slightly agree == 3, and agree gets the value 4.
but as.numeric(x) just converts the factor levels to numerical values according
to their label-order.
Is there a convenient, flexible function that let's you control how the
factor-levels get converted to numerical values?
thanks for any suggestions!
