R is a freely available
language and environment for statistical computing and graphics. Using
the open architecture of SAS Model Manager, you can
register and import R models. SAS Model Manager requires a model
template file and model component files that are created specifically for R models.
The following SAS components
are required to use R models in SAS Model Manager:
-
Ensure that the installed R language
version is 2.13.0 or later.
-
SAS/IML. You must license
SAS/IML because the IML procedure is required to export
SAS data sets to R and to submit R code.
-
The RLANG system option. You must
set this system option.
-
The R language and SAS/IML must
be installed on the same machine where the SAS Model Manager server
is installed.
SAS Model Manager supplies three R model
templates that you can use, or you can create your own template as well. The R model templates
that are provided by SAS Model Manager support the analytic, classification, and
prediction model functions. The
segmentation model function is not supported for R models.
After the model component
files are registered, you can perform all SAS Model Manager
functions except for exporting an R model to the SAS Metadata Repository.
To use R models in SAS Model Manager,
do the following tasks:
-
Ensure that the RLANG
system option is set. To have the RLANG system option set when SAS
starts, have your site administrator add the RLANG system option to
the SAS configuration file.
-
SAS/IML must be installed
before you build an R model.
