This can be useful for dealing with overplotting. violin plots are similar to box plots, except that they also show the kernel probability density of the data at different values. The easiest way is to import a map from a package, such as the maps or rnaturalearth packages, but in this tutorial we are going to use maps. So, for example: ggplot(dfLong, aes(x = noise y = mu, fill = meas)) + geom_tile() + scale_fill_gradientn(colours = terrain. We’ve previously shown how R can be used to read in spatial data, reproject spatial data, and resample spatial datasets. surf is a list specifying a (fitted) surface to be added on the scatter plot.
