Weird Caching Issue
Hey all,
Here''s the issue... I''m not entirely sure it''s even a Cache-related issue,
but here it goes:
I''ve deployed a Rails app onto a subdomain of my clients site... The server
is running Apache2, and I''m proxying through to Lighttpd. The issue I''m
having is that I''m able to add content to the site (data exists in the db),
but

Sum by categorical variable
Dear R-list,
I have two variables (numerical and categorical) and would like to have the
sum (and maybe some other statistics) of the numerical variable by the
categorical one.
Can you help me,
Thank you,

How to make legend with line+ character
Dear all,
I have a multiline plot with each line labeled with a different letter.
But I'm not able to make the legend display the same kind of pattern
'-a-', instead the letter is overwritten by the line. A simpler legend
with only the letter is not very visible and the pt.bg does nothing with
letters. Any idea?
plot(1:10,10:1,lty=1,type='b', lwd=2,pch='a')

optim: abnormal termination in lnsrch (resend)
[sorry, forgot some details...]
I'm using optim(param, fun, method='L-BFGS-B', lower=lo, upper=up) to
minimize a certain function.
Often the minimization ends with the message:
ERROR: ABNORMAL_TERMINATION_IN_LNSRCH
What is optim() trying to say?
What have I to change in my function to make the minimization succeed?
Do you think using BBoptim() instead of optim() changes anything?

Win upgrade pb (virus)
I just upgraded my Win7 32bits installation to 2.14.0 after deinstalling
2.12.x
First thing I moved the win-library from 2.12 to 2.14 and executed a
update.packages(ask='graphics',checkBuilt=TRUE)
(Swiss mirror).
This aborts with the console message:
Error in if (any(diff)) { : missing value where TRUE/FALSE needed
And the antivirus (AVG) pops up complaining that colorspace.dll

density() vs. KernSmooth::bkde
Any advice when to use denstity() and when the KernSmooth package bkde()
to smooth a histogram?
No specific problem to use either one, but I'm curious why there are two
so similar implementations.
Thanks!

Subsample points for mclust
Hi all!
I have an ordered vector of values. The distribution of these values can
be modeled by a sum of Gaussians.
So I'm using the package 'mclust' to get the Gaussians's parameters for
this 1D distribution. It works very well, but, for input sizes above
100.000 values it starts taking really forever. Unfortunately my dataset
has around 4.6M values...
My question: is it

Location of libraries in Windows
I'm preparing to install 2.13, so I need a clarification about package
location on disk.
On window the packages I have installed are under
C:\Users\mvalle\R\win-library\2.12
and the ones that come with R are under "C:\Program Files\R\library"
If I execute update.packages() from the R gui, it fails because it finds
e.g. Matrix as a package that should be updated

Can I disable Cairo?
On Linux 2.13 by default links cairo, so png() uses it for rendering.
One of my users has performance problem, so ask if it possible to
temporary disable cairo during png() rendering so it reverts to grGraphics.
My workaround for now is to configure R without cairo, but this affects
all users that are forced to load and use CairoDevice if they wants
better quality.
I want to avoid this, is it

FYI: matrix surprise
Some time ago someone asked for things that make R difficult to
master. Here I want to record one R behavior that took me off-guard
yesterday. Moral of the story: vectorialize, but don't exaggerate.
Hope it helps

Artifacts in filled.contour+pdf
Dear all,
I'm using R 2.12.0 on Windows 7 (32bits)

Table or file as STDIN to the R Script
Hi all,
I am trying to call the R script/ R Program via my Shell Script. I need to
pass a file to the R script as an argument. When I am trying to do that I am
getting error and only first line of the file is being read. Can you tell me
how should I do that so that it reads the entire file in a R object so that
later I am able to process the matrix operation on that file. It is a tab

strange behaviour of median
During some experimentation in preparing R lessons I encountered this
behaviour which I can not explain fully
mat <- matrix(1:16, 4,4)
df1 <- data.frame(mat)
> mean(df1)
X1 X2 X3 X4
2.5 6.5 10.5 14.5
Expected, documented
> median(df1)
[1] 6.5 10.5
Rather weird, AFAIK there shall not be an issue with data frame at least I
did not find any in help page. I tracked it

levels
Hello,
Thanks to all for the previus answer. I want to be more detailed:
I have a dataset called gm20011231 with 1304 observations (or records).
I want to create a subset with the followin command
j2<-gm20011231[1:10,"V4"]
the levels of "V4" is 1304 and the and the length(j2) is 10.
Do you know how to obtain a j2 with level 10?
Thank you

Compact sums in functions definitions
I'm trying to make more compact the definition
of a function as for example:
f <- function(x) 2/x+3/x
by simply defining the array of coefficients
arr = c(2,3)
and setting:
g <- function(x) sum((arr/x))
Everything seems to work fine because the values returned
by f and g result coincident for different values of their
argument, but when I try to plot the function g using:

levels of an array (strings and numbers)
Reading a csv file (db.csv) as:
yes,full
no,full
no,empty
I can use the command 'levels' to extract
the different values appearing for each
column as follows:
> d<-read.csv("db.csv")
> levels(d[,2])
which returns
> [1] "empty" "full"
while, doing the same with a numerical csv file as:
1,6
0,6
0,7
the same instruction returns an empty
