Attempt to Determine Script's Filename — try.this.path • this.path

try.this.path() attempts to return this.path(), returning this.path(original = TRUE) if that fails, returning NA_character_ if that fails as well.

try.this.path(contents = FALSE, local = FALSE, n = 0,
              envir = parent.frame(n + 1),
              matchThisEnv = getOption("topLevelEnvironment"),
              srcfile = if (n) sys.parent(n) else 0)

try.shFILE()

Arguments

contents, local, n, envir, matchThisEnv, srcfile: See ?this.path().

Details

This should NOT be used to construct file paths against the script's directory. This should exclusively be used for diagnostic messages / / warnings / / errors / / logging. The returned path may not exist, may be relative instead of absolute, or may be undefined.

Value

character string.

Examples

try.shFILE()
#> [1] NA
try.this.path()
#> [1] NA
try.this.path(contents = TRUE)
#> NULL
