why does [A-Z] include 'T' in an Estonian locale?
Inspired by this old Stack Overflow question
https://stackoverflow.com/questions/19765610/when-does-locale-affect-rs-regular-expressions
I was wondering why this is TRUE:
Sys.setlocale("LC_ALL", "et_EE")

TRE's documentation at

alpha-numeric order bug (PR#3996)
I am running R version 1.7.1 on 3 different operating systems:
Linux RedHat, Linux Slackware, and Windows 2000.
R is ordering alpha-numeric character strings in different ways, dependent
on the operating system. R orders strings exactly the same on Slackware and
Windows,
and this ordering corresponds to SPlus. It's the RedHat that is creating the
problem.
On Slackware, Windows, and SPlus:

format numbers into percentages
Hi,
I am currently using the following to formate numbers into percentages:
x=0.00112
paste(round(x*100,2),"%",sep="")
I am wondering if there is a built in R function that does the same. Does
anyone know?
Thanks,

Dear List
I have run into some problems with boot.ci from package boot. When I
try to obtain a confidence interval of type bca, boot.ci() returns the
following error when the data set i large:
Error in bca.ci(boot.out, conf, index[1L], L = L, t = t.o, t0 =
t0.o, :

danish characters - installing R - linux redhat 8.0
I'm using R on a linux redhat 8.0 installation.
The special danish characters (ÅØÆæøå) are showed wrong on the screen.
Example:

),c("Stemmer")))

Any hints?

Is there something wrong with R version 3.0.2 (2013-09-25) -- "Frisbee Sailing"?
Hi,
pnorm(-1.53,0,1) under version 3.0.2 gives 0.05155075. I am pretty sure it
should be 0.063. Is there something wrong with this version of R?

Which gls models to use?
Hi,
I need to correct for ar(1) behavior of my residuals of my model. I noticed
that there are multiple gls models in R. I am wondering if anyone
has experience in choosing between gls models. For example, how
should one decide whether to use lm.gls in MASS, or gls in nlme for
correcting ar(1)? Does anyone have a preference? Any advice is appreciated!
Thanks,

function to generate weights for lm?
Hi,
I would like to use a weighted lm model to reduce heteroscendasticity. I am
wondering if the only way to generate the weights in R is through the
laborious process of trial and error by hand. Does anyone know if R has a
function that would automatically generate the weights need for lm?

stack charts right on top of each other
Hi,
I tried to stack two charts on top of each other using the following
R functions:
par(mfrow=c(2,1))
plot(rnorm(1:3),xaxt="n",xlab="")
plot(rnorm(1:3))
This created two charts, one on top of the other, but there is too much
space between them. Does anyone know how to elimiate the space in between
the charts?
Thanks,

How to reformat data from database into data.frame?
I'm trying to find a clever way to re-map data from a database
query into a data.frame.
Querying a database often returns a table (data.frame) like this:
GeneID MethodID Value
6 1 123
6 2 456
6 3 987
7 1 234
7 3 432
8 2 190
8 3 34
8 1 864
Note that GeneID=7 doesn't have a value for MethodID=2.
Note that GeneID=8 doesn't have the

how do I find the row index number, or row name, of a given value in a vector?
Hi,
I noticed that max(x) returns the maximum value of a vector, but the
function doesn't give the user the option of retrieving the row index number
instead. If I used max(x) to find the maximum value of vector x, then is
there a function I can use to find the index number, or row name, of the
maximum value?
Thanks,

R function for percentrank
Hi,
Does anyone know if R has a built-in function that is equvalent to Excel's
percentrank, i.e., returns the rank of a value in a data set as a percentage
of the data set?

question about scale() function
Hi,
The documentation for scale() states:"If center is TRUE then centering is
done by subtracting the column means (omitting NAs) of x from their
corresponding columns". But it seems that R is subtracting something else
instead of the column mean:
> x=c(2,4,3,4,5)
> mean(x)
[1] 3.6
> x-mean(x)
[1] -1.6 0.4 -0.6 0.4 1.4
> scale(x)

Problem with data type recognition and conversion
Hi,
I have a CSV file with two columns; the first column is date, second column
is numbers. I used read.csv() to load the file into the variable temp.
Somehow, R could not recognize my numbers as double. Instead, it thinks
these numbers are integer even though they all have decimal points (isn't
that strange?). The problem I ran into is that if I tried to convert the
numbers to double using

How to add background color of a 2D chart by quadrant
Hi,
I have a 2D chart that is divided into four quadrants, I, II, III, IV:
plot(1:10,ylim=c(0,10),xlim=c(0,10),type="n")
abline(v=5,h=5)
text(x=c(7.5,7.5,2.5,2.5),y=c(2.5,7.5,7.5,2.5),labels=c("I","II","III","IV"))
I would like to fill each quadrant with a background color unique to the
quadrant. Does anyone know how to do this in R?
Thanks,
