Stable version from the CRAN

The stable version of the package is available on CRAN servers, which means that you can install it with the regular install.packages() function.

If for some reason, the installlation from CRAN fails, you might need to look into alternative methods.

Alternative methods

Stable version from GitHub from source

For the sake of completeness and simplicity, the sources of the stable version are also available on GitHub. The install.packages() function can be used to install this from source - but you will have to install dependencies of the package, and you have to have a compiler installed on your system

Development version - the raw

If you encounter technical problems with the package that are not described anywhere, you might want to take a look at the development version.

If you wish to install the development version, I recommend a manual installation:
1. Clone the repository to your local hard drive.
2. Make sure that you have the package dependencies, and a compiler installed: on Windows, RTools should include all the tools you need, on Mac, you will need to have XCode - if you use GNU/Linux, you have to go down deeper in the rabbit hole :).
3. Open a terminal and navigate to the directory where you cloned. The icosa directory should be visible from there.
4. Run this line in the terminal

  • If you see an error suggesting that R is not found, you have to add it to your PATH environmental variable.
  • If the R packages that icosa depend on are not installed, you have to install them manually, or you will get an error.
  • You can also try devtools::install_github().
