In zzawadz/iCacheR: Utils for caching

Simple example:

slow_function = function(n)
{
  Sys.sleep(n) # sleep for n secs
  rnorm(1000)
}

system.time(slow_function(2))

##    user  system elapsed 
##       0       0       2

library(iCacheR)

cache_function = ic_cache(slow_function)

system.time(t1 <- cache_function(2)) # first use - normal time

##    user  system elapsed 
##    0.00    0.00    2.02

system.time(t2 <- cache_function(2)) # second - read cached value

##    user  system elapsed 
##       0       0       0

all(t1 == t2)

## [1] TRUE
