Some lintr
messages show the potential replacement for a linter, e.g. in any_duplicated_linter
:
library(lintr)
lint(
text = "any(duplicated(x), na.rm = TRUE)",
linters = any_duplicated_linter()
)
#> <text>:1:1: warning: [any_duplicated_linter] anyDuplicated(x, ...) > 0 is better than any(duplicated(x), ...).
#> any(duplicated(x), na.rm = TRUE)
#> ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
However, some messages are not very helpful because they don’t recommend any replacement. For example, package_hooks_linter
says Don't use cat() in .onAttach().
:
lint(
text = ".onLoad <- function(lib, pkg) cat('hi')",
linters = package_hooks_linter()
)
#> <text>:1:31: warning: [package_hooks_linter] Don't use cat() in .onLoad().
#> .onLoad <- function(lib, pkg) cat('hi')
#> ^~~
Is it possible to suggest the replacement for this linter? My reflex was to use message()
instead but this is also flagged. Same with packageStartupMessage()
(only flagged in .onLoad()
, not in .onAttach()
) so I don’t know what should be used here.
