Namespace Tampering ^[overview]

This rule ports the following steps of R CMD check (see the conformance table for the legend):

#	Step	Coverage	Note
37	R code for possible problems (book)	🟩⭐	⭐ also quick fixes, deprecated arguments, environments resolved through variables, hooks followed into callees

This rule is a best-effort rule.

Finds unlockBinding() and assignInNamespace() on other namespaces, .Internal() calls, and library.dynam() given a file extension.
This linting rule is implemented in src/linter/rules/cmd-check/namespace-tampering.ts.

Configuration

Linting rules can be configured by passing a configuration object to the linter query as shown in the example below. The namespace-tampering rule accepts the following configuration options:

• checkInternal
  report .Internal calls (default true)
  R CMD check #37

Examples

patch <- function() assignInNamespace("mean", function(x, ...) 42, "base")

The linting query can be used to run this rule on the above example:

[ { "type": "linter",   "rules": [ { "name": "namespace-tampering",     "config": {} } ] } ]

Results (prettified and summarized):

Query: linter (2 ms)
   ╰ Namespace Tampering (namespace-tampering):
       ╰ certain:
           ╰ assign-in-namespace of base at 1.21-74
