check() new R package

Question

Why check() is not able to find function in my package? I have a small package with function iv.num. My example in documentation is iv.num(german_data,"mob","gbbin"). If I run check(), I get error - could not find function. However, I am able to run the function without any problems as shown below. I'm using R 3.0.1. and devtools (using load_all() before check(). Unfortunately, I am not able to create reproducible example, the package is on github

* checking examples ... ERROR
Running examples in 'riv-Ex.R' failed
The error most likely occurred in:

Answer 1

You did not export iv.num. I saw that by looking at the NAMESPACE file.

Add #' @export to the roxygen comment block above iv.num like you did with your other functions that are being exported.
