In previous posts I have querried and visualized data related to US automotive industry, using public data provided by e.g. the Federal Reserve or the US bureau of labor statistics.
As a further reference, I wanted to plot a graph on total US passenger car and light commercial vehicle sales, according to calsalesbase.com
The data has been copied from here: http://carsalesbase.com/us-car-sales-data/
Using my other posts, it can be cross-validated.
data_df = read.csv2("passenger cars and light commercial vehicles.csv", header=TRUE, stringsAsFactors = FALSE, sep=",") library(ggplot2) ggplot(data_df) + geom_point(aes(x=year,y=sales/1000000),color="black",size=3) + geom_path(aes(x=year,y=sales/1000000),color="red",size=2,alpha=0.5) + labs(title="Total annual US passenger car and light commercial vehicle sales", subtitle="Data according to carsalesbase.com, in mio. units (for US automotive industry)") + xlab("year")+ ylab("sales volume [mio units]")+ ylim(0,18)
