Not a SIG-Mac issue.
You seem to missing an operator between 2 and (, and I am guessing you  
meant to type "*" or ":") but it is not clear SINCE YOU HAVE NOT  
DESCRIBED THE PROBLEM WELL. (And you have not posted the exact error  
message either.)

Also check FAQ for description of problems related to the hierarchy of  
arithmetic operators in R (I don't actually remember a FAQ nubmber for  
this one but it is "frequently asked":
 > x <- 1:10
 > 2:length(x) -1
[1] 1 2 3 4 5 6 7 8 9
So have you checked at the ends of your ranges to see if these indices  
are meaningful? What is length(x) and would it be meaningful to  
request x[2-1 -3]? What is x[-2]  (or perhaps x[1-3] ) , after all? Or  
x[length(x)
More likely that the extremes would raise "out of range" problems than  
the "interior" indices.
Better problem description, better punctuation,  and posting to rhelp.

Hi Sandy,

Why don't you usw runmean() of the caTools package??
In the see also section of the help for runmean() there are various other possibilities given.

Good Luck
Gerald

Also rollmean or rollapply in package zoo. Eg:

library(zoo)
rollmean(as.zoo(1:25), 5)

G'day all,

I am having a problem with a function in surveillance package when trying to use one function on my mac (either GUI or commandline). It works fine on FreeBSD, and the contributor uses Linux or windows, so I thought I might ask here first - my apologies in advance. Many of the package functions work absolutely fine on all three.

Using the spatio-temporal cluster detection function stcd, and using the example in the help file, the final command takes about 1 second to return a result on FreeBSD (output of sessionInfo() first):

All the commands run fine, except that the final one does not finish, and after an initial flash of enthusiasm, R ticks along between about 3 and 15% of CPU chewing up as much memory as it can. I have attached a sample at the very bottom of this email, taken before I killed it off.

I realise this could be a package function, but I know almost nothing about what goes on under the R hood, so if this helps to find a problem in the package I am very happy to switch to go back to the package authors with some help.

Thank you for your help,

cheers
