Namespace linter

Arguments

check_exports	Check if symbol is exported from namespace in namespace::symbol calls.
check_nonexports	Check if symbol exists in namespace in namespace:::symbol calls.

  linters = namespace_linter()
)

# okay
lint(
  text = "stats::sd(c(1, 2, 3))",
  linters = namespace_linter()
)

lint(
  text = "stats::ssd(c(1, 2, 3))",
