Hi All, I have a data frame of three columns, all of which names. The names in the three cols overlap up to a point, so I might have *Harry* in all three columns, *Tom* in cols 1 and 3 and *Bob* in col 3 only.
harry paul bob anita harry tom frank jack harry tom pete ben .... I want to turn the names into numbers, BUT I want the numeric code for, say, *Harry*, to be the same on all columns. Doing cbind(as.numeric(col1), as.numeric(col2), as.numeric(col3)) does not work because the factors are different in each column, hence they get a different number even though the name is the same. Ideas? Cheers Federico -- Federico C. F.
