One step way to create data frame with variable "variable names"?
Suppose
plotx <- "someName"
modx <- "otherName"
plotxRange <- c(10,20)
modxVals <- c(1,2,3)
It often happens I want to create a dataframe or object with plotx or
modx as the variable names. But can't understand syntax to do that.
I can get this done in 2 steps, creating the data frame and then
assigning names, as in
newdf <- data.frame( c(1, 2, 3, 4),

How to save a model in DB and retrieve It
I'm wondering how to save an object (models like lm, loess, etc) in a DB to retrieve and use it afterwards, an example:
wind_ms <- abs(rnorm(24*30)*4+8)
air_kgm3 <- rnorm(24*30, 0.1)*0.1 + 1.1
wind_dg <- rnorm(24*30) * 360/7
ms <- c(0:25)
kw_mm92 <- c(0,0,0,20,94,205,391,645,979,1375,1795,2000,2040)
kw_mm92 <- c(kw_mm92, rep(2050, length(ms)-length(kw_mm92)))

International characters
I am new to Ruby on Rails. I have read a lot, and bought several books,
and now I have started to implement a modified "shopping cart",
following the AWDWR-book, with modifications to suit our application
(subscriptions and memberships).
Having done up to chapter 7 I have had no real problems, except one:
Since our customers are Swedish I need the screen names, texts etc to be

CMS centos3
Anyone using or recomend a content management system that will install
without out a lot of mucky muck on a Centos3 system? I looked at Zope
but it needs a newer Python, Midgaard looks likes it's geared towards
RHEL4. OpenCMS looks like it runs on java so that might work. I have
yet to look at Rubyrails and Django.

Legacy database Oracle
I am new to RoR, but totally sold to the concepts, so I have decided to
use RoR to develop a web client to our Oracle-based software that our
customers today use with a Windows client. At first we will develope
simple things like registering to receive email newsletters, and
registering/updating your name, address and telephone etc. Eventually we
hope to do a more full-bodied web-side client.

frailty
Hi R-users
I spend a lot of time searching on the web but I didn?t found a clear
answer.
I have some doubts with 'frailty' function of 'survival' package.

IronRuby's Marshal.dump doesn't work with CLR types, or ruby types backed by a CLR type
Backstory: I''m trying to use DRb for some in-house utility code. DRb
itself seems to work fine, but I found that when I misspelled a method
name, instead of reporting back a NoMethodError, the IronRuby process
crashed immediately to the console.
This is using a relatively recent build of IronRuby from Github
Steps to repro:

no one cares about i18n (was [OT]: Asking questions on this list)
Do most others in the community agree with this statement? It seems to me
that i18n is:
1. Actually important to many people
2. Not really the difficult to implement in concept
3. Something that people like to point out about Rails to say it''s not
ready foir "Enterprise"
It seems to be that a big part of Rails is encouraging people to do things

function in R that's equivalent to SQL's "IN"
Hi all,
I'm trying to find
something like the "==" operator that will work on vectors or something
equivalent to SQL's "IN" function. For e.g., if I have:
x <- c(1,2,3,4,5)
y <- c("apples", "oranges", "grapes", "bananas", "pears")
z <- data.frame (x,y)
w <- c(2,4,5)
I want R to return the values

LiteSpeed
Yo Zed,
Just curious -- what do you think of the LiteSpeed
server? Is it better than Lighty? Does it (gasp!) also
serve Rails apps like Mongrel? I think I read that
LiteSpeed doesn''t have proxying support.
Thanks,
Joe

The size of static libraries is relevant because it places an upper
bound on the size of the executable. Otherwise we can only speak
