It is possible to get help informations on various methods and classes by two different procedures:

• Each method or class has a help file accessible through the R console:

# One way of doing it:
R> ??methodName
# Another way:
R> help(methodName)

• Each package has a more extensive documentation through the use of vignettes. If the package has more than one vignette, a text-based chooser is presented with number-based selections. You access the vignettes like this:

R> openVignette(package_name)

• More to come…
