Using ggplot2, generate a histogram plot (binsize = 1) that looks like below. Use facet wrap to separate the plots for the different columns. You will need to use melt function from reshape2 package (covered in lecture notes and video) to prepare the data frame in a usable input format for ggplot2. Write a few lines to describe what inferences you can make from this analysis.
