In TalhoukLab/biostatUtil: Utility Functions Used in Biostatistics Projects

Do a jitterplot among subtypes

Description

Generates stripchart (jitter plot) of a biomarker split on a categorical subtype.

Usage

doJitterplotAmongSubtypes(
  input.d,
  data.description,
  biomarker.var.name,
  biomarker.name,
  subtype.var.name,
  subtype.name,
  pch = ".",
  jitter = 0.05,
  digits = 3,
  cex.axis = 0.9
)

Arguments

input.d	input data.frame
data.description	title description
biomarker.var.name	variable name of biomarker to plot
biomarker.name	x-axis label for biomarker name
subtype.var.name	variable name of subtype to separate biomarker
subtype.name	y-axis label for subtype name
pch	jitterplot dot type. For example, 20 = small dot, 16 = big dot.
jitter	scalar indicating amount of jitter (spread of points)
digits	number of digits to round to
cex.axis	scalar indicating amount of scaling for axes

Details

Expects subtype variable to be a factor. Also, biomarker and subtype variables have missing cases as NA.

Value

A jitterplot shown across different subtypes
