as.numeric : what goes wrong?
I have a character vector j1 created from dimnames and want it to convert it to numeric. Like the first element: > j1[1] f896 1 896 > as.numeric(j1[1]) [1] 1990 why is it not 896 as it should be? This is true fr the whole vector. Thanks W.P. [[alternative HTML version deleted]]
