To accomplish R integration with Minitab Statistical Software, Minitab, LLC provides the mtbr package. The following descriptions of the functions from the mtbr package prepare you to write R code that integrates with Minitab.
For information on how to install Minitab's R package and how to run R from Minitab, go to Installing R to use with Minitab Statistical Software.
For more information on R, consult the guidance available at www.r-project.org.

By default, Minitab uses a different
datetime
format than
R. To convert from the Minitab
datetime
format to the Unix
datetime
format, use the
excel_numeric_to_date()
function from the
janitor
R package.
R on Microsoft® Windows cannot always process strings that have characters from different character sets. For example, if Microsoft® Windows uses the Japanese (Shift-JIS) character set and a string includes characters from the Chinese (GBK) character set, some strings will not be processed correctly.
Because of this limitation, one possible solution is that strings use characters from the same character set as the Microsoft® Windows display language.
