pivotwider and namesep

[arnaudcol]

I have some data I am pivoting wide which has multiple values. I was assuming the nameSep configuration would handle the multiple values, but it doesn't seem to work. It looks like I can only get the last value.
Any guidance on concatenating multiple values?

Ah I suppose this would be similar to the values_fn option in tidyr. This is not currently supported, you'll need to summarize the data beforehand unfortunately
