Some R Packages Installation for Linux
In Jasp Ubuntu installation guide in your site, it is wrote that;
For version 0.8.0.0, extra R packages have to be installed:
install-packages(c("GPArotation","qgraph","RJSONIO","semTools"))
but correct command is;
install.packages(c("GPArotation","qgraph","RJSONIO","semTools"))
Just for attention 
Thansk for your great effort.
