In order to install from source on Windows, you first need to install a set of software dependencies called the " RTools " (available from that link). This link should say something like Download R 3.0.3 for Windows, except the 3.0.3 will be replaced by the most current version of R. Next, click the first link at the top of the new page. On Windows, install.packages() will only install precompiled binaries, unless explicitly forced to install from source (you can read a lot more about this in the R Installation and Administration guide). To speed up compilation on linux or mac, install ccache, then replace /. To install R on Windows, click the Download R for Windows link. It is a good habit to add spaces around an operator to increase readability of the code. For Windows and Mac, CRAN makes pre-compiled binaries available. Lets type 1 + 2 and press Return (on Mac) or Enter (on Windows). On UNIX/Linux, only source code is distributed and all packages are compiled from source during installation (for packages written entirely in R, this is trivial!). Or you can prepare compiled "binaries" matched against common systems, so that people can run code without having to know how to compile it.ĬRAN uses a mixed strategy. You have two choices when distributing code for compiled languages: you can distribute source code only, and expect the user to have the right compiler software (and skills) to build system-specific runnable code themselves. These languages need accessory software tools to translate ("compile") their source code into machine language that can run on a particular system. However, some R packages have significant portions written in other, compiled languages, usually C/C++ or Fortran. Figure 5.2: MAC values of LIM/O3 SOM dissolved in 2 mL of water (black. Since R is an interpreted language, source code written in R doesn't have to be translated into system-specific machine language before running. 3.3.4 Compounds found exclusively in the emissions from brushwood/chulha cook.
