A correlation is a statistical measure of the relationship between two variables. The measure is best used in variables that demonstrate a linear relationship between each other. The fit of the data can be visually represented in a scatterplot. Using a scatterplot, we can generally assess the r...

Function for making a correlation matrix plot, using ggplot2. The function is directly inspired by Tian Zheng and Yu-Sung Su's corrplot function in the 'arm' package. Please visit github.com/briatte/ggco for the latest version of ggcorr, and see the vignette at briatte.github.io/ggcor ...
Highlight using annotations and color If you want to use a scatter plot to present insights, it can be good to highlight particular points of interest through the use of annotations and color. Desaturating unimportant points makes the remaining points stand out, and provides a reference to comp...
Before going into each of these four uses of the scatter plot let us first see how it may be constructed in EXCEL and what the data points in the resulting plot tell us. In addition, we will also see how a line of best fit may be constructed for the given plot. This line of best...
