Qanalyst

An R package for building and visualizing quality control charts. Depends also on a package not on CRAN at the moment but available on my Github: chartconstants.

Please note that the package is currently under development so it probably is buggy and the documentation is still in progress.

Requires:

• dplyr (>= 0.3.0.2)
• lazyeval
• ggplot2

So far the implemented functions include:

• Functions for generating control charts (SE and NSE version).
• Functions for setting user defined parameters on a chart.
• Function for simple static plotting.

Future features to be implemented:

• Integration with Shiny
• Interactive plotting (possibly with ggvis)

Implemented charts

Currently the following charts are available:

• Charts for variables: xbar-s, xbar-r, s, r.
• Charts for attributes: c, p, np, I, mr, u.

Examples

Each function is documented with an example, check each function documentation. I’m going to write a tutorial on the package when it is finished.
