Details

The default cache for map images is tempdir()/mapmiscCache, which will be deleted when an R session ends. Running this function sets a cache in /tmp/mapmiscCache_[username], which will re-use cached data across R sessions.

Examples

# current cache
getOption("mapmiscCachePath")

# set a new cache
myCache = file.path(tempdir(), 'myCache')
dir.create(myCache)
options(mapmiscCachePath = myCache)
getOption("mapmiscCachePath")

# create a persistent cache
# \donttest{
persistentCache(verbose=TRUE)
# }
getOption("mapmiscCachePath")
