shk_vs_contcov: Shrinkage contribution versus continuous covariates

In xpose.xtras: Extra Functionality for the 'xpose' Package

Shrinkage contribution versus continuous covariates

Description

Mirrors eta_vs_contcov(), but for the per-individual shrinkage contribution diagnostic (shk type columns, see derive_shk()/backfill_shk()) instead of the etas themselves.

Usage

shk_vs_contcov(
  xpdb,
  mapping = NULL,
  shkvar = NULL,
  covvar = NULL,
  drop_fixed = TRUE,
  linsm = FALSE,
  type = "ps",
  list = TRUE,
  title = "Shrinkage contribution versus continuous covariates | @run",
  subtitle = "Based on @nind individuals",
  caption = "@dir",
  tag = NULL,
  log = NULL,
  guide = TRUE,
  facets,
  .problem,
  quiet,
  ...
)

Arguments

xpdb	<xp_xtras> or <xpose_data> object
mapping	ggplot2 style mapping
shkvar	tidyselect for shk variables
covvar	tidyselect for continuous covariate variables; NULL (default) selects every continuous covariate in the xpdb data index.
drop_fixed	As in xpose
linsm	If type contains "s" should the smooth method by lm?
type	Passed to xplot_scatter
list	<logical> Only relevant when shkvar resolves to more than one shk column. If TRUE (default, for backwards compatibility), returns a plain list of one plot per shk column. If FALSE, they are instead combined onto one shared plot – faceted by shk column, in addition to the existing per-covariate facet – automatically paginating (at most 9 panels per page, i.e. ncol/nrow of 3) via xpose's own facet_wrap_paginate mechanism. Printing the returned plot renders every page; pass page to print() to select a specific one.
title	Plot title
subtitle	Plot subtitle
caption	Plot caption
tag	Plot tag
log	Log scale covariate value?
guide	Add guide line?
facets	Additional facets
.problem	Problem number
quiet	Silence output
...	Any additional aesthetics.

Value

The desired plot, or (when shkvar resolves to more than one shk column and list = TRUE) a plain list of one plot per column.

Examples

xpdb_x %>%
  backfill_shk() %>%
  shk_vs_contcov()

# Combine all shk columns onto one shared, faceted plot instead of a list
xpdb_x %>%
  backfill_shk() %>%
  shk_vs_contcov(list = FALSE)
