[Rd] Error message library()
Dear all,
When one tries to load a non-installed package you get the error:
Error in library(xyz) : there is no package called 'xyz'
I noticed on several occasions that this puzzles beginners. Therefore I suggest
to change the error description in:
Error in library(xyz) : there is no package called 'xyz' installed on this
machine. Check the name of the package or use install.packages("xyz") to
install it.
Best regards,
Thierry

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

Couldn't R even directly ask for installing if it exists on CRAN? Like:
Error in library(xyz) : package 'xyz' is not installed on this machine.
Do you want to install it? [Y/n]

Please, no! We don't want to enter the realm of the computer assuming it knows
what you want to do (which is becoming too common nowadays, unfortunately,
making the interaction more and more annoying). For some users this error
simply means that they mistyped the package name, so fetching CRAN repos on
that behalf ranges somewhere between overkill and stupidity. If the user can't
type install.packages() then I am certainly not confident that the user can use
R for any reasonable data analysis.
Cheers,
Simon

If we need to connect to CRAN to do that, I indeed withdraw my suggestion. I had in mind a feature that's present in Bash in some recent Linux distributions: when a program doesn't exist on the system, tell the user in what package it can be found (it also detects typos in program names). > If the user can't type install.packages() then I am certainly not > confident that the user can use R for any reasonable data analysis. There's certainly some truth in your statement. ;-) OTOH it seems package authors have tried raising the barrier to a quite high level, and even when knowing what you do, you can get the package names wrong. Consider for example : Snowball, but snow and snowfall rJava and rJython, but RODBC and RWeka (not to pick on Kurt at all, there are many other examples, but I'm mainly using these - great - packages) Maybe a less controversial improvement would be to ask "Did you mean XXX?" if a package with a very similar name is *installed*. That wouldn't require fetching information from CRAN, and would most of the time be helpful (people install packages they use).

Re: [Rd] Error message library()
Thierry,
I agree with you and think that computers _should_ help users.
When R tells me a package does not exist, it is almost never because I
typed an incorrect package name.
Almost always it is because:
(1) I am using an old script with a new version of R and have not yet
installed a package.
(2) I am running a current script on a different machine that does not have
a package installed.
(3) I am copying some code from the web and have not yet installed a
package.
MiKTeX does a nice job of auto-installing packages in a silent manner.
I've tried to imitate that with the function below. I add this to
.Rprofile. Then use "lib(pkg)" to install and attach packages
automatically. The function is rough and needs improvement, but works
reasonably well.
Kevin
assign("lib",
function(p=NULL, ...){
# Why ... ?
p <- substitute(p)
if(!is.null(p) & !is.character(p))
p <- deparse(substitute(p))
print(p)
ip <- rownames(installed.packages())
# Should be more clever here and only install some of 'p'
if(!(p %in% ip)) install.packages(p)
require(p, ..., character.only=TRUE)
}, env=startup)
