Hello,
can anybody help me with this problem?
I have a dataframe, which contains its values as factors though I have numbers
but it was read as factors with "scan". Now I would like to convert these
columns (multiple) to a numeric format.
# this example creates a similar situation
testdata <- as.factor(c("1.1",NA,"2.3","5.5"))
testdata2 <- as.factor(c("1.7","4.3","8.5",10.0))
df <- data.frame(testdata, testdata2)
what do I have to do to get the same datafram but with numeric values???
Antje
