Saving/loading background image not working; also can't load mask image

System information (version)

• trackR => 0.1.1
• Operating System / Platform => Mac OS X 10.9.5
• R => 3.3.3
• CMake => 3.13.1

Detailed description

Video loaded and background estimated. On clicking "Save background file", am prompted with a dialog box to choose a directory and file name for the .png file. Despite selecting an appropriate directory and file name, after clicking "Save", the dialog box goes away without error... and no image is actually saved. I've repeated this with other directories and file names, with the same result.

Three additional points of note:

• In the background image save dialog, I also cannot make a new directory. Despite the option, following the steps to make a new folder doesn't actually make one, no error is given, the directory just isn't made.
• I also cannot load a background image (e.g. one from Simon) based on the same video clip I'm working with.
• I also cannot load a mask image. No error is given.

@jameswaters Given that you are using a version of R that is almost 2 year old, I'm going to guess that the problem might be there. If I remember correctly, there has been big changes when R transitioned to v3.5 and that has broken a lot of things. Can you try with an up-to-date version of R (3.5.1)?

This might be the most up to date version I can run on Mac OS 10.9.5. Really didn’t want to have to upgrade the OS... but yes, i’ll have to try on a newer machine.

@jameswaters Any luck? Can I close this issue and blame it on your out of date R installation? ;-)
