Map flipper_length_mm to the x axis and species to fill. , store your plots in a list (say qplt), and use do. Our analyst has performed a propensity score analysis on our data. I want to plot the variable Age against its density from both datasets in a histogram and overlay it for Create labels with labs() Initialize the graph with ggplot() and provide data Map flipper_length_mm to the x axis and species to fill Set alpha to 2/3 19. I think it can be done without but that is the way the package is This tutorial explains how to overlay several density plots in ggplot2, including several examples. Overlaying histograms are needed whenever we have two or more different data sets that need to be compared, for this reason, these are also called If I had 2 different variables to plot as histograms, how would I do it?
