The QuaSAR tool had stopped installing properly due to incompatibility of the required R packages with R 3.0.1.

To restore function, two changes were made to the original files provided in QuaSAR-1_32.zip.

The Quasar.properties file was edited to call R, 4.0.0, instead of R 3.0.1.

The InstallPackages file was edited to change "http:" to "https:" in the call for downloading packages from the cran site.

These changes reenabled proper tool installation and function in Skyline in our lab.

These two modified files, and all other required files originally provided by the QuaSAR tool site in the file QuaSAR-1_32, are provided here in the file QuaSAR-2020.0.zip for vetting.

Happy 12th anniversary to Skyline on this first day of the ASMS Reboot!
