grdplot: Gradient Plot

In melren/effiplot: Flexible functions to create plots for efficacy analysis in clinical studies

Description

Generate a flexible gradient plot (heatmap or bubble plot) for efficacy analysis

Usage

grdplot(type = "heat", data, x, y, facet = NULL, ord,
  ord_lbl = "USUBJID", reverse = FALSE, ncol = 3, title = "",
  xlab = "Subjects", ylab = "Study Day", leglab = "", caption = "",
  size = "small")

Arguments

type	use either "heat" or "bubble", controls the type of plot produced (string)
data	a dataframe containing the input data to plot (dataframe)
x	column name for x-axis parameter (string)
y	column name for y-axis parameter (string)
facet	optional parameter, column name containing a subgrouping factor to facet the plot by (string)
ord	column name for factor level parameter to order color gradient by (string)
ord_lbl	column name for parameter that contains x-axis labels (ord column labels) (string)
reverse	optional boolean parameter for flipping the size of the bubbles and for "negative" measurements like decrease/percent decrease (logic)
ncol	optional parameter to control number of facets to display in a row if facet variable is provided, must be at least 1, default value is 3 (integer)
title	optional parameter, custom plot title (string)
xlab	optional parameter, custom x-axis plot label (string)
ylab	optional parameter, custom y-axis plot label (string)
leglab	descriptive label for heat map legend (string)
caption	optional string to include as a caption on bottom of plot (string)
size	optional string to specify font size schema ("small" for PDF usage or "large" for Shiny apps) to use for plot, default is "small" (string)

Value

produces a gradient plot with optional facet parameters

Examples

grdplot(
  type = "bubble", data = AZA, x = "RANK", y = "ADY", facet = "CHRTGRP", ord = "PDCR",
  reverse=TRUE, ncol = 2, xlab = "Subject ID", leglab = "% Decrease in UA"
)

grdplot(
  type = "heat", data = AZA, x = "RANK", y = "ADY", facet = "CHRTGRP", ord = "PDCR",
  reverse=TRUE, ncol = 2, xlab = "Subject ID", leglab = "% Decrease in UA"
)

grdplot(
  type = "bubble", data = AZA, x = "RANK", y = "ADY", facet = "CHRTGRP", ord = "AVAL",
  ncol = 2, xlab = "Subject ID", leglab = "Ulcer Area"
)
