One can rename a field:
mtcars %>% rename(bla = mpg)
But if the field doesn't exist, an error:
mtcars %>% rename(MPG = mpg, CYL = cyl, bla = uyhgfrtgf)
Error: Can't rename columns that don't exist.
x Column `uyhgfrtgf` doesn't exist

I looked at ?rename_if and it says this is now superseded by rename_with().
What's the 'right' way to attempt to rename fields but with a possibility they don't exist (e.g. in this case a ShinyApp with filter selectors).
