As I was preparing for an R intro course I came up with the idea of creating a fake data set that is stuffed full of all the conceivable errors one can imagine. Just in case my imagination falls short, I’d appreciate all the suggestions in the comments so that I can incorporate more errors.
There is a Hungarian saying about the veterinarian’s horse to describe
a case that exhibits all the possible conditions a subject can suffer from
(read more of the etymology here).
I would like to create a data set that shows all the
possible errors a data set can exhibit. This data would be then used in

So far I have been able to come up with the following issues:
"1,234,567.0058654"(needs to clear commas, turn it into numeric, digits are irrelevant but eating up memory)
0-3works fine, but
I don’t imagine that this list can ever be complete, but right now it is far from complete. If you have struggled with a problem in the past and would like others to learn from it, please leave a comment and I will expand the list accordingly.
An update (v 0.1-1) of the intrval package was recently published on CRAN. The package simplifies interval related logical operations (read more about the motivation in this post).
So what is new in this version? Some of the inconsistencies in the 1st CRAN release have been cleaned up, and I have been pushed hard (see GitHub issue to implement all the 16
These operators define the open/closed nature of the lower/upper
limits of the intervals on the left and right hand side of the
in the middle as in
c(a1, b1) %o% c(a2, b2).
