...

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")
#> ✔ Installed: ggplot2
#> # A tibble: 1 × 4
#>   package name    installed source
#>   <chr>   <chr>   <lgl>     <chr> 
#> 1 ggplot2 ggplot2 TRUE      CRAN  

# Check without auto-install:
check_pkg("r-lib/devtools", source = "GitHub", auto_install = FALSE)
#> ✔ Installed: devtools
#> # A tibble: 1 × 4
#>   package        name     installed source
#>   <chr>          <chr>    <lgl>     <chr>
