[R] Variable passed to function not used in function in select=... in subset

I have the problem that in my function the passed variable is not used, but the variable name of the dataframe itself - difficult to explain, but an easy example:

TestFunc<-function(df, group) {
    print(names(subset(df, select=group)))
df1<-data.frame(group="G1", visit="V1", value=0.9)
TestFunc(df1, c("group", "visit"))

[1] "group"
But I expected and want to have [1] "group" "visit" as result! Does anybody know how to get this result?
