Hi folks,
I'm following An Introduction to R
http://cran.r-project.org/doc/manuals/R-intro.html#R-and-statistics
to learn R.
Coming to;
2.2 Vector arithmetic
v <- 2*x + y + 1
Warning message:
In 2 * x + y :
longer object length is not a multiple of shorter object length
What does it mean? How to rectify it? Please help. TIA
What does this return:
c(length(x), length(y)) # ?
