Is there a command in R to view all the functions present in a package?

I would like to know if there is a command, using which one can view all the functions that are built into an R package.

For example, let's say I loaded a package into environment:

require(dplyr)

Now, I would like to get a list of all the functions present in the dplyr package.

Is there any way to get such a list?

You can use lsf.str.

For instance:

lsf.str("package:dplyr")

To list all objects in the package use ls

ls("package:dplyr")

Note that the package must be attached.

To see the list of currently loaded packages use

search()

---

Alternatively calling the help would also do, even if the package is not attached:

help(package = dplyr)

Finally, you can use RStudio which provides an autocomplete function. So, for instance, typing dplyr:: in the console or while editing a file will result in a popup list of all dplyr functions/objects.
