Scatterplot_Matrix: Interactive Scatterplot-Matrix

In corneliusfritz/intervisu: Interactive data visualisation with shiny

Description

Takes any data and creates an interactive Scatterplot-Matrix with multiple features.

Usage

Scatterplot_Matrix(data, metr_data = F, width = c(400, 700, 400),
  height = c(500, 700, 500))

Arguments

data	A data.frame object that is to be analyzed (all categorical variables with be transformed to metrical variables)
metr_data	A logical value, indicating whether a table showing the metric and categorical analogies of levels should be shown
width	A three-dimensional numeric value indicating the width of the three shown plots
height	A three-dimensional numeric value indicating the height of the three shown plots

Details

At first one has to choose the variables to be plotted in the scatterplot matrix. Once the user has choosen at least two variables (the minimum of a scatterplot), those two plots are also shown on each side of the Scatterplot-Matrix. The user though can decide what scatterplots out of the Matrix should be zoom in on each side. A conventional click on one scatterplot from the Scatterplot-Matrix triggers a bigger scatter plot on the left-hand side, while you can control the scatterplot on the right-hand side with a double click on the desired scatterplot in the Scatterplot-Matrix. On each of the small scatterplots one can select certain points with the brush option, implemented in the R-packge Shiny. Once you have chosen a cloud of data points and performed a normal click, the chosen points with be colored red in all available scatterplots. If you want to see the chosen data you have to press the "show data"-Button. A linear regression line and a loess curve can also be plotted by pressing the fitting button. In the case of a pressed "Regression"- or "Smooth"-Button. If groups have been definied by brushing actions, you can also plot the linear and loess regression by group once you pressed the Button "By Group".
