R-help, After cogitating for a while, I finally figured out how to define a data.frame column as factor and assign the levels within a function... BUT I still need to pass the data.frame and its name separately. I can't seem to find any other way to pass the name of the data.frame, rather than the data.frame itself. Any suggestions on how to go about it? Is there something like value(object) or name(object) that I can't find?
#sample dataframe for this example y <- data.frame( one=c(1,1,3,3,5,7), two=c(2,2,6,6,8,8)) > levels(y$one) # check out levels NULL # the function I've come up with fncFact <- function(datfra, datfraNm){ datfra$one <- factor(datfra$one, levels=c(1,3,5,7,9)) assign(datfraNm, datfra, pos=1) } >fncFact(y, "y") > levels(y$one) [1] "1" "3" "5" "7" "9" I suppose only for aesthetics and simplicity, I'd like to have only pass the data.frame and get the same result.
