ok. I will give the example for which i m getting this error. The data for plotting R chart and S chart is very huge. SO i will take example for plotting C chart. Data is a follows :- sample D size trial 1 11 1000 TRUE 2 11 1000 TRUE 3 13 1000 TRUE 4 11 1000 TRUE 5 14 1000 TRUE 6 12 1000 TRUE 7 17 1000 TRUE 8 7 1000 TRUE 9 7 1000 TRUE 10 6 1000 TRUE 11 9 1000 TRUE 12 3 1000 TRUE 13 2 1000 TRUE 14 4 1000 TRUE 15 13 1000 TRUE 16 11 1000 TRUE 17 7 1000 TRUE 18 11 1000 TRUE 19 8 1000 TRUE 20 5 1000 TRUE 21 37 1000 TRUE 22 11 1000 TRUE 23 9 1000 TRUE 24 4 1000 TRUE 25 7 1000 TRUE 26 4 1000 TRUE 27 17 1000 TRUE 28 11 1000 TRUE 29 18 1000 TRUE 30 21 1000 TRUE 31 18 1000 TRUE 32 19 1000 TRUE 33 12 1000 TRUE 34 11 1000 TRUE 35 13 1000 TRUE
Here my sample size is 1000 for each sample no. 1st column corresponds to sample no. 2nd column corresponds to no. of defects 3rd column corresponds to sample size 4th column , I have kept asTRUE because I want to consider whole data for calculating the control limits. The code which i use is as follows :- library(qcc) y<-read.table("Defect_data_2008.csv",sep=",",header=TRUE) attach(y) obj<-qcc(D[trial],sizes=size[trial],type="c") But while plotting C chart I am getitng following error Error in plot.new() : figure margins too large For plotting the pchart if I just change the type="p" then it is plotting correctly without error. -- View this message in context: http://n4.nabble.com/problems-with-SPC-charts-in-R-tp1467901p1468451.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
