Do a jitterplot among subtypes

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

Value

A jitterplot shown across different subtypes

Details

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