If the anycodings_casting values are mostly unique, there won't be anycodings_casting much difference in speed. The speed anycodings_casting difference will be most apparent for anycodings_casting long vectors with few levels. Why is as.numeric(levels(f)) more anycodings_casting efficent than anycodings_casting as.numeric(as.character(f))?Īs.numeric(as.character(f)) is anycodings_casting effectively as.numeric(levels(f)), so anycodings_casting you are performing the conversion to anycodings_casting numeric on length(x) values, rather than anycodings_casting on nlevels(x) values.

Values, anycodings_casting as.numeric(levels(f)) isĪnycodings_casting recommended and slightly moreĪnycodings_casting as.numeric(as.character(f)). Transform a anycodings_casting factor f toĪpproximately its original anycodings_casting numeric Happen anycodings_casting by implicit coercion. Is there a better way to convert a factor to anycodings_r numeric?Ī anycodings_casting factor is meaningless, and may I have to resort to paste to get the real anycodings_r values: as.numeric(paste(f))

f <- factor(sample(runif(5), 20, replace = TRUE)) When I convert a factor to a numeric or anycodings_r integer, I get the underlying level codes, anycodings_r not the values as numbers.
