Good morning, I have some problem adding ablines in Rstudio. The lines drew by the software doesen?t match with the added values, what can I do? pfaOK<-qcc(D[!trial], sizes=size[!trial], type="p", nsigmas=2, data.name="Polli positivi al Campylobacter") pfaOK1<-qcc(D[!trial], sizes=size[!trial], type="p", data.name="Polli positivi al Campylobacter") abline(h=pfaOK$limits[1], lty=1, col="red") abline(h=pfaOK$limits[2], lty=1, col="red") abline(h=0...

...I use the same command to plot the R chart and S chart jus by replacing the type="Xbar" by type="R" and Type="R" ,I am getting folloiwing error Error in limits.R(center = NA_real_, std.dev = NA_real_, sizes = c(1000L, : group size must be less than 51 when giving nsigmas In addition: Warning message: In sum(sizes * statistics) : Integer overflow - use sum(as.numeric(.)) obj<-qcc(D[trial],sizes=size[trial],type="p") Similarly I am able to plot P chart for defective dataset successfully using following command y<-read.table("Defect_data_2008.cs...

Hi Gents, I need to get the control limits from qcc function. As follows: qcc(MDI, type = "xbar.one") Call: qcc(data = MDI, type = "xbar.one") xbar.one chart for MDI Summary of group statistics: Min. 1st Qu. Median Mean 3rd Qu. Max. 0.3266 0.4249 0.4371 0.4333 0.4451 0.4858 Group sample size: 1 Number of groups: 383 Center

You shouldn't use R charts for monitoring dispersion using sample sizes larger than 20, and for sample sizes greater than 25 you get an error. From theory, R chart used the distribution of relative range for estimating sigma, which is tabulated up to a sa...
