e.g. intersection_point() non-intersections and non-point intersections alike will be NA

see https://www.geometrictools.com/Documentation/DistanceToCircle3.pdf for 3D

intersection is one of them

Hi Thomas,

Thanks for the effort put into {euclid}. Great logo by the way!

Now, to the issue: can we represent the region $-x_1 + x_2 \leq -5$? And can we plot it? What about intersections of regions like these? Such functionality would be great to accompany exercises on linear programming.

Running on Intel Mac OS Ventura 13.6.3 , RStudio 2023.12.1+402, R (2023-10-31, Eye Holes)

First hurdle: installation failed 'cause mpfr not installed . Problem solved.

Second hurdle: I am getting the error log copied below with one error and one warning both outside my competence level!

Please advise.

Regards
M.P.

A typo in the here

A vector can, as with points, be created from a set of x and y coordinates, but you could also created it from a vector of points:

could have also created or could also create?

So I'm trying to install euclid on my windows machine that has R.3.6.3 installed. devtools is installed and working fine. My suspicion is cgal incompatibility with mingw , but can this be sorted purely at the R level?

I double checked that the most recent Rtools has been installed.

I am unable to install euclid. The install process seems to be running indefinitely, but the following is a snapshot
