is a package for statistical process control and control charts built based on the qcc
package, with new functions allowing the use of beta control charts.

As the package uses the qcc
package as the basis for building the graphics, all qcc
functions and utilities also work on bcc
. For more informations please consider visiting https://luca-scr.github.io/qcc/.
You can use bcc
in two basic ways:
discrete data representing the sample size using type = 1
;
continuous data without sample size with values in the range between [0.1] using type = 2
; you can make a ratio between the data to be analyzed for example.
data("Montgomery2005") bcc(data=Montgomery2005$Defective, sizes = Montgomery2005$Sample, type=1)
data("Drapper1998data") bcc(data = Drapper1998data, type = "2")
