[FEATURE REQUEST] mutate(across()) ?

[jayoung]

Hi there,

I've been enjoying plyranges - thank you!

Would it be possible to add a mutate(across()) sort of functionality? (or maybe it already exists and I haven't found it)

I'm finding mutate(across()) very useful for mutating multiple columns of tibbles, and would love to do the same for GRanges objects. Right now I'm cheating by doing this sort of thing:

gr %>% 
  as.data.frame() %>% 
  mutate(across(starts_with("counts"), function(x) {log2(x)} )) %>% 
  as("GRanges")

Which isn't too bad really, but it might be nice to avoid going back and forth.

thanks!

Janet
