library(data.table) #version 1.9.4
estim <- data.table(aa=c(1,2,3), vvat1at=c(1,5,16))
checked=TRUE
If had some check and it is TRUE, then in variable estim create new variable a with value 1.
if (checked) estim[, a:=1]
But automatically printed out data.table.
# aa vat1at a
#1: 1 1 1
#2: 2 5 1
#3: 3 16 1
Can some something to do that not printed out this data.table when I not wanted?
