%description
Functionality required to efficiently use R with IBM(R) Db2(R) Warehouse
offerings (formerly IBM dashDB(R)) and IBM Db2 for z/OS(R) in conjunction
with IBM Db2 Analytics Accelerator for z/OS. Many basic and complex R
operations are pushed down into the database, which removes the main
memory boundary of R and allows to make full use of parallel processing in
the underlying database. For executing R-functions in a multi-node
environment in parallel the idaTApply() function requires the 'SparkR'
package (<https://spark.apache.org/docs/latest/sparkr.html>). The optional
'ggplot2' package is needed for the plot.idaLm() function only.
