Hello,
You should put all those data frames in a list and then use the list
(just one object).
But if you have several objects in your workspace and need to write a
function that accepts a varying number of arguments, use the dots argument:
df.set - function(..., by){
dots -
A minor quibble.
I would argue that R best practice would be to keep the summarization
and printing separate; viz
df.set - function(...){
dots - list(...) # all those objects in a list
}
