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
#> [1] 1

## check to see if a path exists
tmpdir <- file.path(tempdir(), "example_checkPath")

dir.exists(tmpdir) ## FALSE
#> [1] FALSE
tryCatch(checkPath(tmpdir, create = FALSE), error = function(e) FALSE) ## FALSE
#> [1] FALSE

checkPath(tmpdir, create = TRUE)
#> [1] "/tmp/RtmpzknuyG/example_checkPath"
dir.exists(tmpdir) ## TRUE
#> [1] TRUE

unlink(tmpdir, recursive = TRUE)
