[R] Files and classes in a package?

While installing my small package, I met a tricky problem. For clarity, let me explain it with the following simplified example. In ~/pkg/R/aclass.R, setClass(“aclass”, contains=”bclass”, representation(i=”numeric”)) In ~/pkg/R/bclass.R, setClass(“bclass”, representation(j=”numeric”)) Af

RE: [R] where does R search when source()?

I agree that this is a good use for a script, but I don't think it's what Daehyok was talking about. He wants a library of frequently used scripts to be available in multiple projects. In R, the best way to do that isn't to use scripts at all, it's to put the code in functions. What I asked is t

Considering replies to my question, typical practices of R users seem: 1. Creating a special function to source frequently used scripts. 2. Creating a personal package containing frequently used scripts. Both of them needs additional steps to edit the function or to create/install the package when

The reason I asked is to separate script files from data files. Usually, I am working in the directory containing data files, but some script files are in other shared directories. In the case, is there any way to access the script files conveniently without specifying its absolute path? In other w

Exactly where does R search for foo.R if I type source(“foo.R”)? Only from current working directory (same as getwd()), from all directories specified by e.g. $PATH? Thanks. Daehyok Shin __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/m

The interface for dates in R is a little confusing to me. I want to create a vector of Date objects from vectors of years, months, and days. One solution I found is: years <- c(1991, 1992) months <- c(1, 10) days <- c(1, 2) dates <- as.Date(ISOdate(years, months, days)) But, in this solution the
