how does one apply Western Electric / AT&T rules to R plots?
I have searched for info on how to apply the Western Electric rules for
process control, to data and plots I have in R, but I have not been able
to learn how.
Any help would be greatly appreciated.
Thank you,

Time series merge?
I have two time series
a <- ts(1:10, start=c(1,6), end=c(2,5), frequency=10)
b <- ts(1:5, start=c(2,1), end=c(2,5), frequency=10)
Obviously 'b' is a subset of 'a'. I want a single index value indicating
where that start of 'b' lines up with the start of 'a'. So in this simple
example I would expect an index of 5. I was playing with 'merge'.

RowSums Question
I have a question on RowSums.
Lets say i have a timeSeries table
A B C
1/1/90 NA 1 1
1/2/90 NA 1 1
1/3/90 NA 1 1
1/4/90 NA 1 1
1/5/90 1 1 1
1/6/90 1 1 1
if i use RowSums, i will get
1/5/90 3
1/6/90 3
but i want
1/1/90 2
1/2/90 2
1/3/90 2
1/4/90 2
1/5/90 3
1/6/90 3

It certainly is encouraging to know that others also have been confused by
aspects of
