UPDATED ONLINE COURSE MATERIAL class 07. ppt (pdf): vector dot-product function R: scripts/ vectorfunctions. R myfunctions. R climatology. R, plot_climatology. R is an example how to concentrate all user-interactions with the program to a few lines at the top of the program: This makes a program re-usable. Give it a try: change the station name, and the year-range of the calculation for the climatological cycle. You will find an example at the end, how to write results to a data file. plot_climatology. R is a program to plot the results. It shows you how you can read back in the created data file. Note: try these scripts and compare with our previous scripts albany_climatology. R
