[R] problems with SPC charts in R

[vikrant]

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.
