You could do something like this:
> revtrunc <- function(x) { x - floor(x) }
> revtrunc(39.5)
[1] 0.5
But note:
> revtrunc(-39.5)
[1] 0.5
I'm not sure what you'd want for negative numbers. One possibility:
revtrunc <- function(x) { sign(x) * (x - floor(x)) }
> revtrunc(39.5)
[1] 0.5

hello there,
Is there a way of truncating in the opposite direction so as to retain only
the values to the right of the decimal??
i.e. rather than:
> trunc(39.5)
[1] 39
i would get something like:
> revtrunc(39.5)
[1] 0.5
I've been searching to no avail but I imagine there is a very simple
