Hi All,
i am very new to R and need guidance.
Need help in doing process capability Analysis for my data set (6 months of
data) given in below format:
Date | Opportunities | Defectives | DefectivesInPercent
I searched and found that pcr() from QualityTools package can be used for
this purpose. The USL is 2% defectives.
MyData = read.csv(file.choose()) #select CSV file that has data in above
mentioned format.
x <- MyData$DefectivesInPercent
pcr(x, distribution = "negative-binomial", usl=0.02)
I get error message as:
Error in pcr(x, distribution = "negative-binomial", usl = 0.02) :
y distribution could not be found!
Please advise, how to proceed?
Regards,
Prasad DN
