I have tried to do some capability studies using SixSigma package with function: ss.study.ca(). However I get an error:
Error: Unknown parameters: binwidth
Even trying the example:
ss.study.ca(ss.data.ca$Volume, rnorm(40, 753, 3),
LSL = 740, USL = 760, T = 750, alpha = 0.05,
f.sub = "Winery Project")
is not working as well and gives the same error
does anyone have the same problem with SixSigma package?
Additionally I have tried to go for qcc package and i found there is a function for process
capability six-pack plots (process.capability.sixpack()). This function is stated in the publication http://www.stat.unipg.it/luca/Rnews_2004-1-pag11-17.pdf but not available at the moment ...
What kind of package would help me to perform the capability studies?
Thanks for any help
