R help - Jun 2012 - remove descriptions from output

Dear R users,

I'd like to remove some descriptions when I use "filter". 
> filter(1:10, rep(1, 3))
Time Series:
Start = 1 
End = 10 
Frequency = 1 
 [1] NA  6  9 12 15 18 21 24 27 NA


That is, I want only this

 [1] NA  6  9 12 15 18 21 24 27 NA

Thank you in advance.

Kathie

Dear Kathie,

Try

 c(filter(1:10, rep(1, 3)))

Hi,

You could also use rollapply () from zoo
library(zoo)
?t2<-as.numeric(rollapply(1:10,3,sum))
[1]? 6? 9 12 15 18 21 24 27
t1<-c(filter(1:10, rep(1, 3)))
t1<-t1[!is.na(t1)]
?identical(t1,t2)
[1] TRUE

A.K.

Use as.vector() on the output of filter.

It is recommended that one should *not* use c() for its
side effects.  Better to use as.vector().
