R & GGPLOT – Expanded Plots

>>GET THE R CODE<< R and GGPLOT are great! There are some things, however, that I want to be able to do easily. For these things I have to create template codes, which I want to share with you! This time around I wanted to show you how you can create “zoomed” areas of a

#21 – Find significant relationships in data with a CoCo Matrix

The CoCo Matrix (correlation coefficient matrix) is a script for R that takes a table headed with multiple variables and calculates the correlation coefficients between each of the variables, determines which are statistically significant, and represents them visually in a grid-plot. I created the CoCo Matrix to cross correlate a table with a large number of

#13 Mapping in R: Representing geospatial data together with ggplot

I have been trawling around for a while now trying to find a simple and understandable way of representing geospatial data in R, whilst retaining the ability to manipulate the visualisation in ggplot. After much searching I came across some articles which got me to a working product only after a lot of ball ache.

#4 R: A powerful tool for the geochemist

  R is an incredibly powerful programming tool used by a large community of people who require an easy to use, light weight, FREE, and fundamentally awesome statistics package! I have recently discovered that R can be used by geologists whose IT skills are often pitied by their more computer literate geophysicist colleagues. Long story short
