Examples

Run this code
## 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) # clean up
