Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. This is in contrast to hardware, from which the system is built and which actually performs the work.Īt the lowest programming level, executable code consists of machine language instructions supported by an individual processor-typically a central processing unit (CPU) or a graphics processing unit (GPU). Software is a set of computer programs and associated documentation and data. The application software layer interfaces with the operating system, which in turn communicates with the hardware. SAS supports R that is installed and built from the CRAN source.A diagram showing how the user interacts with application software on a typical desktop computer. Since this article was published, some companies have tried to interface between SAS and Anaconda R on Linux. The 64-bit edition of SAS looks first for the 64-bit edition of R and then for the 32-bit edition. The 32-bit edition of SAS looks first for the 32-bit edition of R and then for the 64-bit edition. If you are using SAS software on a 64-bit edition of Windows, you can install either the 32-bit or the 64-bit edition of R.If you are using SAS software on a 32-bit edition of Windows, you must install the 32-bit edition of R.If you are using SAS/IML 9.3 or later, read on. If you are using a version of SAS/IML prior to 9.3, you must install a 32-bit version of R.I'll close with a few comments about 32-bit and 64-bit versions of SAS and R. Consequently, if the interface to R changes, SAS customers need to use a compatible version of R until they can update their version of SAS. Some software companies distribute their own versions of R, but SAS does not. To use R 2.12.0 or later, you must use SAS 9.3 or later.Īn error message that you might see because of incompatible versions is "An installed version of R could not be found," although this message can also occur for other reasons. R 2.12.0, which introduced 64-bit R, changed the locations of certain libraries.To use R 3.0.0 or later you must use SAS 9.4 or later. R 3.0.0 changed certain aspects of the external API to R.R 3.0.2 changed an internal detail that SAS was using.Upgrade the operating system before they can compile R 3.3.0. R 3.3.0 requires Red Hat Linux (RHEL) 7.1, so SAS customers who run an older Linux release might need to On Windows, R 3.3.0 broke compatibility with SAS/IML 14.1 (SAS 9.4m3) and earlier releases.When you try to run R from SAS/IML, you might get error messages that include "ERROR: The final R statement is incomplete" and "ERROR: SAS is unable to transcode character data to the R encoding." You can download a hot fix that resolves the issue for SAS 9.4 M5, M6, and M7. R 4.0 broke compatibility with all SAS releases on Linux.To date, the following releases of R broke compatibility with a prior SAS release: However, after a version of SAS ships, it is impossible to ensure forward compatibility. SAS ensures that each SAS release supports backward compatibility with as many previous R releases as possible. In addition, SAS IML on SAS Viya supports the latest version of R. In the following table, an asterisk indicates that a hot fix is required.Ĭompatibility with R Releases SAS Version Some older versions of SAS only support up to R 3.6.3, which was released in March 2020. The current version of SAS supports R 4.2.0, which was released on 22APR2022. The following table lists recent SAS releases and the versions of R that each supports. SAS release supports which versions of R. However, there have been so many versions of SAS and R since 2009, that it is hard to remember which The interface to R is part of the SAS/IML language. SAS has supported calling R from the SAS/IML language since 2009.
