You can ignore those.

You shouldn't ignore those.  Your package will be tested many, many 
times, and it will take more than 3 minutes for just one example.  (It 
will be tested whenever any package you depend on is changed, to make 
sure the change doesn't break yours.)

Use a smaller dataset, do less, or whatever you can to get the 
multipleRegion_plot example down to a time similar to the other ones, 
i.e. well below 10s in user+system time.

You don't have a lot of control of elapsed time because it will depend 
on what else is happening on the test machine, but if the other times 
are short, usually elapsed time will also be short.
