Ooops, I guess this is FAQ 2.22. But what is the preferred idiom for
those of us who want to avoid the print?

Is there any way of tuning off the printing when using the :=
assignment? I have taken to writing code like
library("data.table")
DT <- data.table(idx = 1:10, key = "idx")
for (i in 1) { # Avoid default print
DT[, v := runif(idx)]
}
just to avoid cluttering my screen. I could of course wrap it in
invisible() instead, though I am not sure that makes for much cleaner
code, or use
DT$v <- with(DT, runif(idx))
when adding new columns. But I thought := was clever and used an
overallocation trick, and I of course wanted to benefit from this.
