I am putting together a document for using R to conduct a Six Sigma project. This text is part personal notes as I learn the software and is intended as an introduction to the software to others.
I'm using the
packages, and I can create a new Control/Shewhart Charts with many of the packages. Due to work constraints, I am not allowed to add additional packages on my own to play with; I can submit a request for later inclusion if there is a package which meets my requirements. The packages I have been using have varying functionality (for example, qcc allows me to create a chart with control limits defined by one portion of a data frame and applied to the remainder of the data frame).
However, I need to be able to create a Control/Shewhart Chart with stages in R. I am familiar with this process in Minitab
, and I have constructed similar chart in excel, but the packages I am currently using—to my knowledge—do not support this.
How could I support this functionality in R?
