Select the file that you just downloaded. The websites for packages generally have a manual in PDF format which may provide additional useful information.

To provide you with an impressive response, we spend a few words on how, why, and when the package was developed, as well as by whom. After all, a bit of historical knowledge does no harm!

Note that both their first names begin with the letter R.

5, 53, 55) You may put spaces on either side of the commas to improve the readability of the code. Spaces can also be used on either side of the ‘‘+’’ and ‘‘<-’’ commands. In general, this improves readability of the code, and is recommended. It is important to use the round brackets ( and ) in the c function and not the square [ and ] or the curly brackets { and }.
