osx - in R createDataPartition how do I pass a value for y coming from a function call -


i created function calls createdatapartition in function, pass dataframe , targety value when call createdatapartition getting following error:

error in createdatapartition(df[target], p = 0.05, list = false) :    y must have @ least 2 data points

is there unique way on how function calls?

code:

targety = 'response' # adultfile dataframe trainpct = .95 my_function <- function (df=adultfile,targety=targety,p=trainpct) {    testidx <- createdatapartition(df[targety], p=p, list = false) }

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
