CrEATE A TIME SErIES ChArT
If you know how to make a scatterplot in R, you know how to make a
time series chart. Load your data and use the plot() function, but
instead of using p in the type argument, you use l as the type , which
stands for line.
To demonstrate, use world population data from the World Bank from
1960 to 2009. As usual load the data with the read.csv() function.
population <-
read.csv(“http://datasets.flowingdata.com/world-population.csv”,
sep=”,”, header=TRUE)
