Rscript -e 'df <- read.csv("data.csv"); png("rhist.png"); hist(df$salary, main="Salary distribution"); dev.off()'

Draw a histogram of salary to a PNG file

hist() bins a numeric vector and draws a histogram, with main setting the title. Wrapped between png() and dev.off(), it writes rhist.png instead of opening a window. Histograms reveal the shape, center, and spread of a distribution at a glance. Adjust bin width with the breaks argument, such as breaks=50.
