Can't download equisse on a mac

[ghost]

I have tried downloading the package using
install.packages("esquisse")
and
remotes::install_github("dreamRs/esquisse")
and i am getting the following error:
Error in dyn.load(file, DLLpath = DLLpath, ...) :

If you install this : www.xquartz.org it should work. It worked for me at least.

I had this issue. It was a pain but basically you need to install some dependencies in order to allow esquiss to run on non windows environments. I did the following from the command line:

1. libfontconfig1-dev needs to be installed with: sudo apt-get install libfontconfig1-dev
2. Cairo needs to be installed with: sudo apt-get install libcairo2-dev a
3. Also do sudo apt-get install libxt-dev

Then I installed esquisse via the RStudio package manager.

It would be great if esquisse could manage these dependencies as part of the package installation- Ill open this up as a separate issue
