R: Extended Scatterplot Matrices

PlotPairs {DescTools} | R Documentation

## Extended Scatterplot Matrices

### Description

A matrix of scatterplots is produced.The upper triangular matrices contain nothing else than the correlation coefficient. The diagonal displays a histogram of the variable. The lower triangular matrix displays a scatterplot superposed by a smoother. It's possible to define groups to be differntiated by color and also by individual smoothers. The used code is not much more than the `pairs()` code and some examples, but condenses it to a practical amount.

### Usage

    PlotPairs(x, g = NULL, col = 1, pch = 19, col.smooth = 1, main = "",
              upper = FALSE, ...)

### Arguments

`x` | the coordinates of points given as numeric columns of a matrix or data frame. Logical and factor columns are converted to numeric in the same way that data.matrix does. Will directly be passed on to `pairs`.
`g` | a group variable
`col` | color for pointcharacter
`pch` | point character
`col.smooth` | color for the smoother(s)
`main` | the main title
`upper` | logical, determines if the correlation coefficients should be displayed in the upper triangular matrix (default) or in the lower one.
`...` | additional arguments passed to `pairs` function.

### Examples

    PlotPairs(iris[1:4], g=iris$Species, main = "Anderson's Iris Data -- 3 species",
              col=c(hred, hblue, hgreen), col.smooth=c("black", hred, hblue, hgreen))
