capturing a figure to PDF or Image
Hello,
I've been using jpeg(), bmp() and pdf() to capture plots.
I've used the parameter "at" in a plot, to define the tickmarks.
It works fine on screen, but when I try to print it to a file, it gives a
warning:
"at" is not a graphical parameter
and prints an empty figure. Can you help?
Thanks,
Eran.

completing missing samples
Hello,
I have a time-series that has some missing samples.
I was thinking on completing them using either zero-order hold or linear
interpolation.
I am looking for an efiicient way (other than a loop...) of identifiying the
missing time slots and filling them.
Can you think of any methods that might help here? (obviously
which(diff(time)>min(diff(time))) will give the locations, but what

R-Studio Question
Hello,
I've switched to R studio from the StatET Eclipse plug-in.
I have a question regarding navigating between plots.
When I use x11() or windows() new devices are created and I know how to
switch back and forth between them.
However, when I plot on the device that stands for R-Studio's built-in plot
browser, is there a way to switch back between plots? Each new "plot"

debugging functions in R
Hi,
I am not sure if this is the right list to ask this question (though I did
not find a more appropriate one).
I've started using R a month ago, and small scripts work fine. However, when
I start writing more complex code, it gets messy.
1. Is there any way to debug "normally", with breakpoints?
2. I am using the Eclipse plugin (StatET), and tried JGR(). Is there an IDE

Namespace in packages
Hello,
I wonder how I might create a package that only reveals some of the function
in the package to the user.
I've tried creating an R package using the following:
f <- function(x,y) x+y
g <- function(x,y) x-y
h <- function(x,y) f(x,y)*g(x,y)
package.skeleton(list=c("f","g","h"), name="mypkg")
and would like only h() to be available when I

Poly-phase Filters in R
Hello List,
I am trying to do the following:
1. Use a BandPassFilter h[n] on a series x[n]
2. Then Decimate the series by a factor D such that y[k]=x[k*D]
The decimation factor is considerable (10,000) so that filtering before the
decimation, using convolve(), seems foolish.
Can you think of an R implementation for a polyphase filter, that uses the
fact that most samples will be thrown away...?

How to navigate (zoom, pan) in a plot/graph
Hello all,
I need to zoom in and out and "travel"(pan) inside a plot, like you can do
on a Matlab plot.
If possible, I would also like the option to use the mouse to set a marker
on the graph and get the (x,y) data for it, again, like in Matlab.
Is this possible in R with the regular packages, or do you maybe know a
different package that will allow this?
Eran.

using a dictionary in R
Hi all,
Is there a way to create a "dictionary" in R, such that it has <key,value>
pairs?
Something to the effect of:
x=dictionary(c("Hi","Why","water") , c(1,5,4))
x["Why"]=5
In truth I'm looking two categorial variables function.
So that if x=dictionary(c("a","b"),c(5,2))
x val 1 a 5 2 b 2
I want to compute

Having a problem with R installation as a shared library
Hello All,
I suspect I am having a problem with my R installation, something that has
to do with "--enable-R-shlib".
Can someone explain if this is something that I can fix using apt-get?
More specifically:
I am having trouble getting installing the RHive package.
I Installed R from scratch, following the instructions in (for example):

Passing a large amount of parameters to a function
Hello,
I have a function with a long list of parameters (of different types,
numeric and string)
myFunc <-function(p1, p2, p3, p4, p5...etc)
{
do.something(p1,p2,....)
}
I want to loop over this to provide a different set of parameters to the
list every time.
for (ii in 1:N)
{
myFunc(p1(ii), p2(ii),....etc)
}
I would like to simplify the notation and use some kind of structure, maybe
