Issue with aggregate.ts and/or %\% on Windows
I've stumbled across an issue with aggregate.ts that either is due to a
misuse of %/% or something deeper relating to numerical precision on
Windows. The test code is
x <- rep(6:10, 1:5)
as.vector(aggregate(as.ts(x), FUN = mean, ndeltat = 5))
On Linux and Mac I get the correct answer
> x <- rep(6:10, 1:5)
> as.vector(aggregate(as.ts(x), FUN = mean, ndeltat = 5)

Omitting NAs in aggregate.ts()
I have a time series vector (not necessarily ts class) that has NAs in
it.
How can I omit the NAs when using aggregate.ts() to compute a function
on each window? If there is at least one non-NA value in each window,
I'd like to proceed with evaluating the function; otherwise, I would
like NA returned. I'm not wedded to aggregate.ts and don't need ts
class if there is another fast,

Cross Spectrum : Conversion of 2-D spectrum into a single complex array
Hi, I'm wondering why the spectrum() phase of quadrature
couple isn't purely +/-pi.
But mostly, I'm looking for a recommended way to take a 2-D
spectrum and convert it into a single complex array.
Kindly consider:
# 10 Hz sine wave 10 seconds long sampled at 50 Hz
deltaT = 1/50
t = seq(0, 10, deltaT)
w = 2 * pi * 10
x = ts( sin( w * t ), deltat = deltaT )
y = ts( sin(

match problem by rownames
Hi all,
While dat['a1',] and dat['a10',] produce the same results in the
following example, I'd like dat['a1',] to return NAs.
dat <- data.frame(x1 = paste(letters[1:5],10, sep=''), x2=rnorm(5))
rownames(dat) <- dat$x1
dat['a1',]
dat['a10',]

create a zero matrix & fill
Dear R user,
I have written a function which returns max,min and variation of a power
(see below)
Power is a given matrix(1,n)
I call the function
>Variation<-VAR(p,(n-deltat))
Now the problem is when I want plot(Results[1],Results[2]). Not possible!
I become the following error (in english it means: Error in
as.double.default(x) :Object cannot be transformed in double)

tcltk freezing using MS Windows for R-2.14+
I am the maintainer of a Bioconductor package (affylmGUI) which uses
tcltk. It freezes inconsistently on MS Windows, but not Mac or Unix. see
details below.
After considerable testing I have reduced the problem from a few
thousand lines of code to 30 lines!
If you paste the following lines of code into an R window:

I run R on MS Windows. In R2.9.0dev, I type ?base to get "R help for package

a sentence:

bnlearn and cpquery
Hi all
I have built a Bayesian network using discrete data using the bnlearn
package.
When I try to run the cpquery function on this data it returns NaN for some
some cases.
Running the cpquery in debug mode for such a case (n=10^5, method="lw")
creates the following output:
generated a grand total of 1e+05 samples.

makeCluster Stall on 32-bit Windows

I'm trying the example cl <- makeCluster(2, type = "SOCK") from the makeCluster documentation and the R command prompt never returns. I am using a 32-bit Windows 10 computer. The problem doesn't happen on another 64-bit Windows 10 computer but does happen on another 32-bit Windows 7 computer. Can anyone reproduce it? Are there any other options that can be passed to

R-devel Digest, Vol 100, Issue 28
I get the same style of path as Hadley. This is on Windows 7 Home Premium with SP1.
I start R by clicking on the R-2.31.0 icon.
I'd assumed that it was a change that came with R-2.13.0!
(On 32-bit Windows XP, which I have just checked, I do indeed get the 8.3 paths.)

R CMD SHLIB changes function name when compiling

I'm trying to write a function in C for implementation with .Call. When
