base packages listed as available on CRAN

[jmbarbone]

Most of the base R packages return TRUE for available_on_cran(). Feels like all of these should return FALSE.

# # get base packages 
# installed.packages() |>
#   as.data.frame() |>
#   # Priority == "base" excludes {translations}
#   subset(grepl("^Part of R", License), "Package", drop = TRUE)

pkgs <- c("base", "compiler", "datasets", "graphics", "grDevices", "grid", 
          "methods", "parallel", "splines", "stats", "stats4", "tcltk", 
          "tools", "translations", "utils")

found <- sapply(pkgs, available::available_on_cran)
split(found, found)
