R Console Free|工具線上App不用買

"R Console Free" app is a version of the open source statistical tool R ported to the Android platform.

This is not a fully version of R (version 3.1.2). Graphics are not enabled in the free version, but R is a console tool, isn't it ? Some features such as completion may not work.

Three compilers have been embedded within the app :

- a C compiler (gcc)

- a C++ compiler (g++)

- a fortran compiler (gfortran)

With these three compilers, you can build and install most of the CRAN R packages from source with the following command :

> install.packages("CRAN package of your choice")

Warning : you will need an active internet connection to build and install CRAN packages.

The default installed packages are :

"KernSmooth" : Functions for kernel smoothing for Wand & Jones (1995)

Once the application is downloaded and installed from the Play Store, the app will copy about 300 Mbytes of data in the app directory on the first run or on update.

The default working directory is the public "Download" folder ("/sdcard/Download").

If you want to enable plots, work with a simple integrated editor then see the app "R Console Premium".
