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,

total rails nuby here. I have a table "thumbnails", hence the model Thumbnail. I''m extending the Thumbnail class with a few constants needed for thumbnail cropping: class Thumbnail < ActiveRecord::Base SOURCE_FILE_PATH = "path/to/source" TARGET_FILE_PATH = "path/to/target" TARGET_WIDTH = 100 TARGET_HEIGHT = 100 end Now, in my controller

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, -- Jonas Stein <news at jonasstein.de>

Thanks for any experiences, (alternative) ideas, or pointers at existing discussions! Regards, Daniel
