Function documentation
Before even thinking of using an R function, you should clarify which arguments it expects. All the relevant details such as a description, usage, and arguments can be found in the documentation. To consult the documentation on the sample()
function, for example, you can use one of following R commands:
help(sample)
?sample
If you execute these commands, you'll be redirected to www.rdocumentation.org.
A quick hack to see the arguments of the sample()
function is the args()
function. Try it out in the console:
args(sample)
In the next exercises, you'll be learning how to use the mean()
function with increasing complexity. The first thing you'll have to do is get acquainted with the mean()
function.
