R Documentation

Check Package Installation Status

Description

Check whether packages are installed and optionally install missing ones. Internally calls inst_pkg() for auto-installation.

Usage

check_pkg(
  pkg = NULL,
  source = c("CRAN", "GitHub", "Bioconductor"),
  auto_install = TRUE,
  ...
)

Arguments

`pkg`	Character vector. Package names or GitHub repos (e.g., "user/repo").
`source`	Character. Package source: "CRAN", "GitHub", or "Bioconductor".
`auto_install`	Logical. If TRUE (default), install missing packages automatically.
`...`	Additional arguments passed to `inst_pkg()`.

Value

A tibble with columns: package, name, installed, source.

Examples

# Check if ggplot2 is installed (will install if missing):
check_pkg("ggplot2", source = "CRAN")

# Check without auto-install:
check_pkg("r-lib/devtools", source = "GitHub", auto_install = FALSE)
