R help - Feb 2011 - preventing repeat in "paste"

Hello!

s<-"start"; e<-"end"
middle<-as.character(c(1,2,3))

I would like to get the following result:
"start 123 end" or "start 1 2 3 end" or "start 1,2,3
end"

How can I avoide this (undesired) result:
paste(s,middle,e,sep=" ")


Thank you!

The easiest thing to do is add a second paste
statement:
> paste(s, paste(middle, collapse=" "), e, sep=" ")
[1] "start 1 2 3 end"
> paste(s, paste(middle, collapse=","), e, sep=" ")
[1] "start 1,2,3 end"
> paste(s, paste(middle, collapse=", "), e, sep=" ")
[1] "start 1, 2, 3 end"

Hi Dimitri,
You can do it like this:

paste(s,paste(middle, collapse=""),e,sep=" ")

Best,
Ista

Sometimes you just have to do something more than once:
paste(s, paste(middle, collapse=','), e, sep=" ")

Try this:
> paste(s, toString(middle), e)
[1] "start 1, 2, 3 end"
