ggInterval_2Dhist {ggESDA}R Documentation

visualize a 2-dimension histogram by symbolic data with ggplot package.

Description

Visualize the two continuous variable distribution by dividing both the x axis and y axis into bins,and calculating the frequency of observation interval in each bin.

Usage

ggInterval_2Dhist(data = NULL,mapping = aes(NULL)
,xBins = 14,yBins=16,removeZero = FALSE,
addFreq = TRUE)

Arguments

data

A ggESDA object. It can also be either RSDA object or classical data frame,which will be automatically convert to ggESDA data.

mapping

Set of aesthetic mappings created by aes() or aes_(). If specified and inherit. aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping. It is the same as the mapping of ggplot2.

xBins

x axis bins, which mean how many partials x variable will be separate into.

yBins

y axis bins.It is the same as xBins.

removeZero

whether remove data whose frequency is equal to zero

addFreq

where add frequency text in each cells.

Value

Return a ggplot2 object.

Examples

ggInterval_2Dhist(oils, aes(x = GRA, y = FRE),
  xBins = 5, yBins = 5)
