Thanks for the PR! I renamed this function mem_sum <- memoise(sum)
has_cache(mem_sum)(1, 2, 3) # FALSE
#> [1] FALSE
mem_sum(1, 2, 3)
#> [1] 6
has_cache(mem_sum)(1, 2, 3) # TRUE
#> [1] TRUE |

This commit creates a new function has.cache( f, ... ) that returns TRUE or FALSE
I use memoisation extensively for network operations. It is sometimes useful to me to use a slow API if it has already been cached and a faster API if the slow API has not been cached. In this case, I want to test whether a function has been cached without actually running it.
