gof_install_suggests: Install the optional packages used by 'run.all.gof()'

In ebrahim.gof: Goodness-of-Fit and Calibration Tests for Logistic Regression

Install the optional packages used by run.all.gof()

Description

The slow tests in run.all.gof rely on optional packages that live in Suggests (givitiR and callr for the GiViTI calibration test, mgcv for the GAM tests, randomForest and dcov for the adaptive BAGofT test (BAGofT itself is used only on request), and ResourceSelection for the Lai-Liu test). Per CRAN policy the package never installs them on its own; this helper installs the missing ones for you, asking first.

Usage

gof_install_suggests(pkgs = NULL, ask = interactive(), update = FALSE)

Arguments

pkgs	Optional character vector of package names to consider. Defaults to the full optional set used by the battery.
ask	Logical; when TRUE (the default in interactive sessions) you are shown the list of packages to be installed/updated and asked to confirm first. Set ask = FALSE to proceed without a prompt (e.g. in a setup script you control).
update	Logical; when FALSE (the default) only the missing packages are installed and anything already present is left untouched. When TRUE the function also checks (via old.packages) which of the present packages are out of date and offers to update those too. The update check contacts your CRAN mirror, so it is a little slower.

Value

Invisibly, the character vector of packages that were installed or updated (empty if nothing was needed).

Examples

## Not run: 
# install whatever optional packages are missing, after confirming:
gof_install_suggests()

# also update any that are out of date:
gof_install_suggests(update = TRUE)

# just the GiViTI dependencies, no prompt:
gof_install_suggests(c("givitiR", "callr"), ask = FALSE)

## End(Not run)
