I'm attempting to pass a string argument into the function randomForest but I get an error:

state <- paste(list("fruit ~", "apples+oranges+blueberries", "data=fruits.data, mtry=2, do.trace=100, na.action=na.omit, keep.forest=TRUE"), sep= " ", collapse="")

model.rf <- randomForest(state)

Error in if (n==0) stop ("data(x) has 0 rows") argument is of length zero.

-Thanks in advance,
