Examples
## normalize file paths
paths <- list("./aaa/zzz",
"./aaa/zzz/",
".//aaa//zzz",
".//aaa//zzz/",
".\\\\aaa\\\\zzz",
".\\\\aaa\\\\zzz\\\\",
file.path(".", "aaa", "zzz"))
checked <- normPath(paths)
length(unique(checked)) ## 1; all of the above are equivalent
## check to see if a path exists
tmpdir <- file.path(tempdir(), "example_checkPath")
dir.exists(tmpdir) ## FALSE
tryCatch(checkPath(tmpdir, create = FALSE), error = function(e) FALSE) ## FALSE
checkPath(tmpdir, create = TRUE)
dir.exists(tmpdir) ## TRUE
unlink(tmpdir, recursive = TRUE)
