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] "C:/Temp/RtmpCQaGyY/example_checkPath"
dir.exists(tmpdir) ## TRUE
#> [1] TRUE
unlink(tmpdir, recursive = TRUE)
