Examples

# choose location to store caches
cacheDir = tempdir()
cacheDir
#> [1] "/tmp/RtmpnwNyJo"
setCacheDir(cacheDir)

# build some caches
simpleCache("normSample", { rnorm(5e3, 0,1) }, recreate=TRUE, timer=TRUE)
#> ::Creating cache::	/tmp/RtmpnwNyJo/normSample.RData
#> <00h 00m 0.0s>
simpleCache("normSample", { rnorm(5e3, 0,1) })
#> ::Loading cache::	/tmp/RtmpnwNyJo/normSample.RData
simpleCache("normSample", { rnorm(5e3, 0,1) }, reload=TRUE)
#> ::Loading cache::	/tmp/RtmpnwNyJo/normSample.RData

# storing a cache after-the-fact
normSample2 = rnorm(10, 0, 1)
storeCache("normSample2")
#> ::Object does not exist::	normSample2
#> NULL

# what's available?
listCaches()
#> [1] "normSample.RData"

# load a cache
simpleCache("normSample")
#> ::Loading cache::	/tmp/RtmpnwNyJo/normSample.RData

# load multiples caches
