Dear All
I'm logging the stdout and stderr of an R program into two separate

I would like to append extra information such as "date", "memory
usage" etc to every line of output that goes to stdout or stderr.

Hi,

Anyway, first of all, your x should not contain 0, so make it, let say,
(1:10)/10.
Secondly, f should not be the density, but -log(density), so in your case it
should be
f <-function(theta) -sum(log(theta) + (theta-1)*log(x))
and finally you must specify a
Hi Daren.
you could try something like:
strings[setdiff(1:length(strings), grep("ba", strings))]
?grep as well as ?regexpr will help as well!

Hello everyone,
I am wanting to replace an element in a matrix with NA. I have used the
following code
dat<-read.table(file="C:\\Documents and Settings\\txt",header=T,row.names=1)
file.show(file="C:\\Documents and Settings\\txt")

Y<-dat[,46:63]

For example,
strings <- c("", "","ccba").
How to get "", "" that do not contain "ba" ?

That's normally how its done so you might want to reconsider whether
you really want only the line segment; however, if you insist see ?segments
plot(y ~ x)
y.lm <- lm(y ~ x)
n <- length(x)
# x assumed to be in ascending or descending order
segments(x[1], fitted(y.lm)[1], x[n], fitted(y.lm)[n])
If this were my problem, I think I'd express it as a Kalman filter
and use the 'dlm' package. Fortunately, the package contains a vignette.
Hope this helps.

cbind the columns, what is the "R-approach" of generating a matrix of 8 columns
that are the averages and standard deviations ? The average and standard
deviation columns should be side by side i.e. A.mean A.sd B.me
Hello Dexter,
I have interest in this topic!
In my search in web, I find things about the MethComp package!
In this package, there is a Deming function ... for Deming regression!

Hi all.
Dear all,
I am looking for a method to draw multiple rectangles in different
colors plus arrows between them (given a data matrix with the relevant
coordinate and size information).
After looking around mainly on:
http://cran.r-project.org/web/views/Graphics.html
and the Rseek page
the Grid p

Hi there,
Simplifying your example a bit, we have:
> a=data.frame(r=c(0,0,1,1),g=c(0,1,0,1))
> transform(a,R=(r>0 && g>0))
r g R
1 0 0 FALSE
2 0 1 FALSE
3 1 0 FALSE
4 1 1 FALSE

r g R
1 0 0 FALSE
2 0 1 FALSE

4 1 1 TRUE

Hi,
I have a table where column 1 has ID numbers and column two has data, and I have
a vector containing a subset of those ID numbers. How can I create a new table
with only the rows from the old table that match the IDs in the vector, like
below:
Original Table:
ID Value

Monna,
The way i do it is to re-create the biplot for the PCA . I am attaching my
code (i am sure this can be done even easier . but this works as well)
where i am using pca() function from labdsv and my data is called veg1.
library (labdsv)
pca.1<-pca(veg1,cor=TRUE)
# The scores are
I just got 37 hits from RSiteSearch('differential equation',
'fun') including odesolv{fda}, rk4{deSolve}, rk4{odesolve}, in addition
to lsoda{odesolve} and the Rsundials package.
hope this helps.

Hi!
I have a bunch of (mainly class) R scripts that I would
like to convert into html pages (although if someone
thinks that what I want to do is easier with latex or pdf,
please tell me).
Considering the format of my files, htmlize() seems the best
option. The only problem is that I would need

Hi List,
Has anyone used R for scoring leads. What has been your experience. I know
the GLM function, but any other functions would help . Also I have tried the
R GUI's rattle and R Cmdr ( a bit pressed for time and regression statistics
).
What would be the best way to go about building this mod
Hi,
I got some problem running the example of arfimaOxFit.
The first three line of the examples I run are:
library(Rmetrics)
x = armaSim(model = list(ar = c(0.5, - 0.5), d = 0.3, ma = 0.1), n =
500)
fit = arfimaOxFit(formula = x ~ arfima(2,1))
The error msg is:
Error in eval(expr, envir, enclos) :
get() is your friend.
Try:
for (x in 1:length(plot))
{
thisdf <- paste("auto.", plot[x], sep="")
plot(thisdf[, 1], thisdf[, 2], col=...)
}
HTH,

Hi,
I noticed whether some one could explain why "&" and "&&" behave differently in
data frame transformations.
Consider the following :
a<-data.frame(r=c(0,0,2,3),g=c(0,2,0,2.1))
Then:
> transform(a,R=ifelse(r>0 && g> 0,log(r/g),NA))
r g R
1 0 0.0 NA
2 0 2.0 NA
3 2 0.0 NA
4 3 2.1 NA
I believe that Deming regression also goes by the name of orthogonal
regression, which can be performed in R using pca methods. If you do a
search of the list for "orthogonal regression" you can see the previous
discussions of this topic.
