Well, it can be done without a temporary variable, but I'm not sure you
would want to.
Anyway...
## simplified example

> eval(substitute(attr(x,"b") <- "hi", list( x = as.name(vname
> a
[1] 1
attr(,"b")
[1] "hi"

Hello everybody,
Has someone the solution to set attribute when variable is known by name ?
Thanks a lot

Let see this exemple:
# The variable name is stored as characters.
varname <- "myvarname"
assign(x = varname, data.frame(A=1:5, B=2:6))
attributes(myvarname)

Hey Matthew,
In addition to what's been mentioned, you may want to look at the
'caret' package, as it provides a nice system for whatever flavor of
cross-validation you're after *and* has a built-in method for `kknn`:

You can paste the directory names, dir.names(files), back on, with
file.path(), after you do the sorting. A better idiom is to use order()
instead of sort() and usng order's output to subscript file.names. E.g.,
the following sorts by year and month number.

Hi Leslie,
Keeping track of any sort of text (or music or pictures) can be
challenging when the number of files becomes large. One way to
organize a large collection is to categorize it in some way that makes
sense to you. Say you create a directory structure:
R_code___
"tags" are a way to label things digitally so that they are easier to find
later - Twitter uses these, as one example.
I found a nice solution: GitHubGist with an interface via Lepton, if anyone
else would like to avoid rummaging through old code to find something (a
function, an example, whatever
Actually there is a difference between:
1. Directly executing the file by the user by double clicking on the
"physical" file (you can only do that from the directory where the file is
located), without going through any terminal, and
2. Executing this file "remotely" by calling it through

I haven't followed this discussion closely, so this may be offbase, but in

I'm trying to get organized about my R programming and I'm looking for a

What's wrong with what you did?

You probably do need to read more about self-organizing maps, since

If you are always running your main script as 'Rscript myscript.R'
then your file argument will appear as '--file=myscript.R' in
commandArgs(). So you can use something like
scriptFile <- function()
{
pat <- "^--file="
args <- commandArgs()
file <- args[grepl(pat, args, args)]
I am curious about why it is desirable for a script to know where in the
file system it is. Is it because you have a set of scripts invoking each
other? If so, the best route it to convert the scripts into functions and
put them into a package. Functions do know which package they live in and
