Hi Everyone,
Thank you all for your input and thoughts on this topic. I've learned much
from this thread. I have arrived at a solution so we can now consider this
topic closed.
I ended up removing the dependency on 'matrixcalc' by (a) replacing
matrixcalc::is.square.matrix() with a basic check

MIT software can be absorbed by GPL2 software, but not vice versa since MIT
allows the code to be further incorporated into and distributed as non-free
software, a permission not granted by GPL2.
I am opposed to people snarfing GPL2 code up for their
On the other hand, MIT does not restrict what you do with your own
contributions, just the included code. GPL restricts rights on
redistributing your own work if a component is GPL as well.

MIT requires that you fulfil: "The above copyright notice and
Write to the CRAN maintainers and let them know about the situation,
hopefully that would prevent archiving.

Hi Everyone, thank you all for your responses.
I agree that I can replicate the three functions within matrixcalc that I
need with ease, even without copying and pasting the original code found in
that package and thus not creating any licensing issues.
I have checked the CRAN incoming boards
The CRAN maintainers almost certainly have tried to contact the
maintainer. You can ask if he plans to fix the bug. If not, if it's
that easy to fix, you could offer to both the maintainers of both
matrixcalc and CRAN to take over maintenance.

After looking up matrixcalc on CRAN, I would recommend contacting the
maintainer, who is listed as:

The reason I say this is what is blowing up the package in the nightly builds
is a careless error in one Example:

Exactly. Is square is just brow=ncol, is positive definite can be
implemented as a check that all eigenvalues > 0, which can be done with
base, and is.symmetric can be simply brute forced in a loop comparing i,j
with j,i.
The fewer dependencies a package has, the more robust it is. It’s a fine
As noted by John Harrold and my previous posting, these are not monster codes.
I'd check what I needed and simply work out enough R to make my package work.
Most of these matrix functions are pretty much old-fashioned math translated
into R. I can't see that R will engage lawyers if the OP
To add another option. In the past when this has happened to me I've found
other packages that provide similar functionality.
I'm assuming that is.square just checks the number of columns == number of
rows? And the others can probably be implemented pretty easily.

MIT is more permissive than GPL2, so there is a collision there. But you may be
able to work it out with the author?

My package uses the MIT license, so would that not meet the compatibility
requirements?
I will attempt to reach out to the package author - thanks for your help!

That all sounds exactly right.
GPL >= 2 allows you to use the material without asking permission as
long as your package is compatibly licensed (e.g. also GPL).
Under normal circumstances it would be polite to ask permission, but
if the reason for doing this is that the maintainer is
Hello,
Thank you for your detailed list of solutions.
I was initially tempted to go with option 1 (move matrixcalc to suggests
and check for its existence before using functions that rely on it), but as
mentioned, this is not a long term fix.
I unfortunately can't take on the responsibilities
I just downloaded the source matrixcalc package to see what it contained. The

I looked at seem fairly straightforward and the OP could likely develop
equivalent features
in his own code, possibly avoiding a function call. Avoiding the function
