Was there anything to indicate that this was a problem in R (and not emacs
nor Windows, especially a Windows driver)?
Those of us who never experience it will not be familiar with `BSOD': it
is I presume the blue screen shown by a fatal error in Windows internals.
I think I have seen just once un
It's certainly a difficult problem to isolate - as you say it may well
be connected to some other combination of application / drivers. I shall
investigate emacs help as a next step.

Dear Feng and everybody
I still have my list of "how to" things for R and sometimes I even try
to add more. Here's the address

I can't tell if you want to have several plots on the same page, in
which case you should use this item:

Hi,
I try to make a dataframe in a loop function, but I dont have succeed.
The function is something like this:
for(i in c(10,12)) {
expr
for(j in c(1:2) {
total <- c(1,2,3,4,5,6,7)
nspf <- length(levels(as.factor(total)))
fin <- data.frame(L=i,N=nspf)
I want to forecast a time series Y using a model that includes previous
values of Y and an exogenous time series X using a transfer function.
The standard procedure as described in Box and Jenkins and numerous
other references is to first fit an ARIMA model to X. Use the ARIMA
model to computer
I think I've figured out the use of "filter" in the ts package, at least
for a simple AR model. I simulated a simple AR time series, modeled it
using "arima", and then used "filter" to compute the 1-step ahead
forecasts:
> y.arma <- arima.sim(list(ar=0.8),n=200)
> y.arma.arima <- arima(y.arma,

I wanted a data frame component to be named "next", for example:
> m <- data.frame (matrix (0, nrow=2, ncol=2))

prev next

200
But "next" being reserved prevents $ indexing without quotes:

I was reading postings to the pgsql-general discussion list for
PostgreSQL and found this interesting reference to PL/R.
The latest postgresql packages for Debian GNU/Linux (unstable) have
PL/R built in to the PostgreSQL server.

Sorry, I should have mentioned that.

There's no bold face in plain text. I assume it's the line inside the loop
that's giving you trouble.
Two approaches:
1. for(i in 1:4) assign(paste("simu", i, sep=""), read.table(...))
2. simu <- vector(4, mode="list")
for(i in 1:4) simu[[i]] <- read.table(...)

Hi,
I think that there is something that I am misunderstanding in creating tables
using dates that are of class POSIXct. Consider:
> x <- data.frame(date = as.POSIXct(strptime(c(rep("2002-10-17", 4), rep("1999-12-08",

Hi,
For computing correlation among variables in a matrix, I use cor( ), but
for computing the p-values I'm using cor.test in the following way:
cor.p <- function(X)
{
res <- matrix(0, ncol(X), ncol(X))
for (i in 1:ncol(X))
for (j in 1:ncol(X)) res[i, j]<- cor.test(X[, i], X[, j])$p.value

If vec is your vector of logical values then
match(TRUE, vec)
should work. It will return NA if there are no TRUE values.

It might not be the most elegant, but it works:

And if there is no 'T', it returns 'NA'

which.max() will coerce the logical to numeric and give the location of
the first max, which is the first TRUE.

Perhaps unrelated but for what it may be worth.
Like many, I fiddle while thinking. Part of my fiddling has been to rapidly
resize the R consule window back and forth by dragging with the mouse on the
bottom right hand corner. I resize the window by a small amount rapidly and
continually . After
I am trying to optimize some code to take advantage of R loop-avoiding
capabilities when working on vectors/arrays that contain time intervals.
The calculation involves adding (for each time interval) the time portion

Can anybody give me a hint why as.POSIXlt doesn't recognize the same
timezones that zdump knows about (Linux Suse 8.1 and Suse 7.3)? Is there
a workaround?
