Hi Tom,
Try this:
> G <- "Number: %s"
> sprintf(G, toString(A))
[1] "Number: 3, 4, 5"

Subject: [R] vector sprintf argument
Hello all:
If I have a vector and a format, I want to do this:
> A <- c(3,4,5)
> F <- "Number: %d, %d, %d"
> sprintf(F,A)
This doesn't work because A isn't three arguments, it's just one.
Is
there a way to peel the vector members out of A so that sprintf can get
at them?
I would like to do this because I have a large set of variable-length
data that I'd like to print out in fancy formatted form. The vectors
range in length from 2 to 7. Each row is different, so I had been
hoping to do this with an array of formats, too.
I feel like I'm either overlooking something obvious, or have determined
to do this in an un-R fashion. Any advice is welcome. (On this topic,
that is.)
Many thanks,
-tom
