Note that, a correlation matrix has redundant information. We’ll use the functions below to set half of it to NA. Helper functions : # Get lower triangle of the correlation matrix get_lower_tri<-function(cormat){ cormat[upper.tri(cormat)] <- NA return(cormat) } # Get upper...
To create our heatmap, we pass in our correlation matrix from step 3 and the mask we created in step 4, along with custom parameters to make our heatmap look nicer. Here’s a description of the parameters if you are interested in understanding what each line does. #Makes each cell squa...
tile, guilt plotetc), but what I wrote was literally just a quick celebratory post to commemorate that I’d finally grasped how to combine reshape2 and ggplot2 to quickly make this colourful picture of a correlation matrix.
