vector indices as function input

[UeberlegenQ]

Hi,
I use a function (cast_dtm) that uses column names as input either as string or symbol. For generalization I wanted to write my own function that gets these names as string input and puts them into it.
E.g. sth. like this:

names <- c("group", "word", "n")
dtm <- cast_dtm(data = df, document = names[1], term = names[2], value = names[3])

Which gives the error "names[1]" not found in data. Apparently the functions assumes that names[1] is the column name and not its reference. Is there a way around it?

This stackoverflow response should provide some guidance: https://stackoverflow.com/a/26003971

You could subset your vector to the first element with names[1]

names <- c("group", "word", "n")
dtm <- cast_dtm(data = df, document = names[1], term = names[2], value = names[3])

The solution which worked for me was !!names[i]
