Why I got warning from the following code?
> assign("x", c(10, 5, 4, 2, 2))
> y <- c(x, 0, x)
> y
[1] 10 5 4 2 2 0 10 5 4 2 2
> v <- 2*x + y + 1
Warning message:
longer object length
is not a multiple of shorter object length in: 2 * x + y
> v
[1] 31 16 13 7 7 21 21 14 9 7 23______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
