With Roxygen2, you write specially-structured comments preceding each function definition. These are processed to produce the. The Roxygen2 comments are just R comments preceded by , but you need to use ' to distinguish the Roxygen2 comments from any normal R comments.
There are still a few of. Include a blank ' line and then write a longer description. The line with return contains a description of what the function returns. This can be split across multiple lines, and you can add extra whitespace which will be copied over to the. Rd file but ultimately ignored. The ' examples line is followed by a set of example R code on how to use the function.
Also look at the Roxygen comments for the brocolors function , which has a more extensive set of examples. We then add a batch of ' comments to each of our functions, so the package now looks like this.
Which will have the lowest KL Divergence. You can call them in R with the? To turn your. Rd file into something you can share, run code like this example code.
Rd file needs to be in the directory that you have set with setwd or set manually with point and click Both the. Rd file you use and the. Never miss an update! There are two different ways to look for documentation on a particular method. The first is to supply the topic argument in the form of a function call, omitting the type argument.
The effect is to look for documentation on the method that would be used if this function call were actually evaluated. See the examples below. If the function is not a generic no S4 methods are defined for it , the help reverts to documentation on the function name.
The first approach will be tedious if the actual call involves complicated expressions, and may be slow if the arguments take a long time to evaluate. The second approach avoids these issues, but you do have to know what the classes of the actual arguments will be when they are evaluated.
