Please install "devtools" package to test gpuga.
> install.packages("devtools")

To load the package, do the following at the project directory.
> devtools::load_all()
(For source packages under development, "library(...)" is not needed.)

R source files are placed in the "R" directory.
OpenCL kernels are placed in "inst/kernels".
Playing around with the library is able by creating/editing files in the "playground" directory.
These files can be run by 'source("playground/foobar.R")' as usual, at the project directory.

gpuga.Rproj was automatically generated when initializing the package with devtools.
It has nothing to do with the functionality of gpuga, so please just ignore it (unless you use RStudio).
