Package ggiraphExtra contains many useful functions for exploratoty plots. These functions are made by both ‘ggplot2’ and ‘ggiraph’ packages. You can make a static ggplot or an interactive ggplot by setting the parameter interactive=TRUE.

Package installation

You can install package ggiraphExtra with the following command.

#install.packages("devtools")
devtools::install_github("cardiomoon/ggiraphExtra")

ggPoints() for interactive scatterplot with regression equation

You can make interactive ggplot easily. You can hover the points, see the regression equations and zoom-in zoom-out with the mouse wheel.

require(ggplot2)
require(ggiraph)
require(ggiraphExtra)

ggPoints(aes(x=wt,y=mpg,color=am),data=mtcars,method="lm",interactive=TRUE)

You can draw scatter plot for binary dependent variable. The GBSG2 data contains data of 686 observations from the German Breast Cancer Study Group 2(GBSG2) study. You can get logistic regression line with a jittered scatterplot by setting the parameter method glm.

require(TH.data)
data(GBSG2)
ggPoints(aes(x=pnodes,y=cens),data=GBSG2,method="glm",interactive=TRUE)

Please check the vignette for “ggPoints” at http://rpubs.com/cardiomoon/231822

ggRadar() for interactive radar chart

You can explore a data.frame with ggRadar() or ggBoxplot().

ggRadar(data=iris,aes(color=Species),interactive=TRUE)
ggRadar(data=mtcars,aes(colour=am),interactive=TRUE)

ggSpine() for an interactive spinogram

ggSpine() is a interactive ggplot version of spineplot(). Spine plots are a special cases of mosaic plots, and can be seen as a generalization of stacked (or highlighted) bar plots. Analogously, spinograms are an extension of histograms. You can add labels by setting the parameter addlabel=TRUE.

require(moonBook)
ggSpine(data=acs,aes(x=age,fill=smoking),interactive=TRUE)
ggSpine(data=acs,aes(x=Dx,fill=smoking),addlabel=TRUE,interactive=TRUE)

## ggBar() for an interactive barplot

ggBar() draws interactive barplot. You can add labels, draw horizontal barplots or polar plots. You can draw histogram with ggBar()

ggBar(acs,aes(x=Dx,fill=smoking),addlabel=TRUE,horizontal=TRUE,width=0.5,interactive=TRUE)
ggBar(rose,aes(x=Month,fill=group,y=value),stat="identity",polar=TRUE,palette="Reds",width=1,
       color="black",size=0.1,interactive=TRUE)
ggBar(acs,aes(x=age,fill=smoking),addlabel=TRUE,horizontal=TRUE,width=0.5,interactive=TRUE)
