[R] question

[jim holtman]

I forgot that you also wanted to change the variable name; I would suggest
that you don't use individual objects, but instead use a 'list'.  Here is
how it would change

result <- lapply(name_file$names, function(.file){
    result <- prep(z, .file)
    saveRDS(result, file = paste0(.file, '.RDS'))
    result  # return value that goes in the list
})

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
