Avoiding a Loop?
Dear R-Helpers,
I have a matrix where the first column is known. The second column is
the result of multiplying this first column with a constant "const". The
third column is the result of multiplying the second column with
"const".....
So far, I did it like this (as a simplified example):
nr.of.columns <- 4
myconstant <- 27.5
mymatrix <- matrix(numeric(0), nrow=5,

How to include files in .R?
Hi,
may be its a very simple question, but i did not find any documentation
about a 'include' command or something like this.
I have to set many constants in my R-files and want to move all these to
one file, so that i can reuse it in all other R-files.
Something like
include("~/R/myconstants.R")
kind regards,

Define package-wide character constants
...a single point of change for that.
I've read documentation on environments, "<<-" and the "assign"
function, BUT am still not sure how to approach my problem BEST.
"assign" could most probably do the job, but do I use/create a certain
environment (like "myConstants")? Or should I just use my package's
environment?
Thanks for any experiences, (alternative) ideas, or pointers at
existing discussions!

Accessing Constants Declared in Helper Modules
Hello all,
I''m having great trouble accessing a constant declared in a helper for
one of my view templates. I am trying to create a grouped selection list
based on a predefined set of values. Rather than declare this set of
values in the view, I wanted to put it in the helper that automatically
gets included for the view. Unfortunately, it doesn''t seem to work.
