I am new to R and I wonder if there is a, possibly easy, way to show a matrix of correlation scatterplots for variables from two data frames (one has 14 and the other 26 variables).
I have found options for correlating one set of variables with itself and nice visualisations - like ggpairs provides (e.g. here http://www.sthda.com/english/wiki/ggally-r-package-extension-to-ggplot2-for-correlation-matrix-and-survival-plots-r-software-and-data-visualization). However, cannot find solution for scatterplotting variables of 2 different dataframes..
Can anyone point me in the right direction how to do this?
OR simply make a series of such plots (does not have to be a matrix after all)?
Thank you and have a good day.
