Helper method for custom distributions

Source: R/utils.R
add_name_attribute.Rd

pprimarycensored() and related functions can identify which distributions are provided via the pdist and dprimary arguments when those are base R functions (e.g. punif, dexp) via the name attribute.

Usage

add_name_attribute(func, name)

Arguments

func

Function, for example the p- or d- form of a distribution function.

name

Character string, starting with "p" or "d" indicating the underlying distribution.

Value

Function, with a "name" attribute added

Details

If you need to use a non-base R implementation, but know the distribution name, you can use this helper function to set it in a way that will be detected by pprimarycensored() and related functions.

This is useful as it enables the automatic use of analytical solutions for distributions where they exist. You can check which analytical solutions are available using methods(pcens_cdf) and check distribution names using pcd_dist_name().

Examples

dist <- add_name_attribute(pnorm, "hello")
attr(dist, "name")
#> [1] "hello"
