Check package installation

Several secondary R packages are used and it's preferable to install them only if they are needed. Placing this check in the body of a function will provide helpful instructions for cases when a user attempts to run a function but doesn't have the required suggested package(s). (The main inspiration of this was because a lot of people had issues installing some packages needed for only specific analysis)

Usage

check_package_installation(pkg, fun = NULL, task = NULL)

Arguments

pkg

(character) the name of the suggested R package

fun

(character) the name of the function that uses pkg

task

(character; optional) the task that fun completes.

Value

TRUE, invisibly, if pkg is installed.

Examples

if (FALSE) { # \dontrun{
result <- MotrpacHumanPreSuspensionAnalysis::check_package_installation(pkg = 'base', fun = 'mean')
result
} # }
