Multiple xyplots
Hi everyone,
I'm hoping you can give me some pointers. I have a requirement to draw
multiple (103) xy line plots onto one output device. Ideally the plots
should be displayed in a hexagonal grid (example at
www.maladmin.com/example.jpg). I can calculate the locations for each
waveform but am wondering how to create multiple plotting areas. I have
come accross references to a package grid (which doesn't seem to be in
my CRAN mirror probability.ca) and lattice but I'm not sure if I'm on
the correct l...

installation problem on Ubuntu
I was able to install the curl library with no problems. However, when I
tried to install ggplot (install.packages("ggplot2")), I got the same
message as earlier, that R can't load internet.so.
Thanks for your help!

OT: Statistics question
I apologise for asking this question here but I am hoping that someone
can either give me direct guidance and/or point me to a better group for
this type of disucssion.
I have what I feel should be a fairly simple problem but which my
limited stats knowledge can't answer. I have two overlapping
distributions (both normal) and I want to answer the question how do I
calculate the cut-off value

matrix indexing
Can someone please give me a pointer here.
I have two matrices
matA
A B C
1 5 2 4
2 2 4 3
3 1 2 4
matB
A B C
1 TRUE FALSE TRUE
2 FALSE TRUE TRUE
3 FALSE FALSE FALSE
how do I extract all the values from matA where the coresponding entry
in matB == TRUE (or FALSE), perferably in vector form.
Many thanks

newbie question
Can someone tell me how I create a vector of numbers where the step
isn't 1?
i.e. x<-(0.0,0.5,1.0,1.5....)

strsplit
I'm stuck on what I feel should be a minor problem.
I have a dataseries obtained from a MS Access database that consists of
a series of numbers seperated by carridge returns (\r)
Currently this data is in R as mode numeric???
I want to separate this into a vector of the componant numbers.
Perhaps a little code will help describe what I've got here!!

understanding DWT
Can someone please help me understand the examples given in the dwt
function of the waveslim library
library(waveslim)
?dwt
I'm having a problem understanding these lines. I assume they are
required because of how the algorythm deals with the signal bounderies.
Am I correct in thinking that for wavelets of scale 1 and 2, the
coefiecints need to be shifted by 2 places, for scale 3 and 4 shift

tree widget question
I'm trying to create an app using TclTk and R
Can someone please explain how I bind a click event to the tree widget
(http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/TreeWidget.html)
Ideally I'd like to bind to particular elements in the tree but tkbind
doesnt seem to work.

Subtracting timeseries objects
Sorry to keep posting but I want to do this right and I'm hoping for
some pointers
I now have two time series objects which I need to subtract.
Unfortunatly the two series dont have the same sample rates.
When I try to subtract them
avgSub<-avg1-avg2
The time series object is clever enough to object.
So I guess I need to write a function for subtraction of the time series
objects which

waveform filtering
I'm not an engineer so I hope I'm using the correct terminology here. I
have a recorded waveform that I want to apply low and high pass filters
too, are tehre already R functions existing to do this or am I going to
have to program my own?
thanks for any pointers

Can someone please show me what I need to get something like this to
work
for(a in c(1:5)){

}
so that i end up with a structure
data$1<-[1,2,3,4,5,6,7,8,9,10]
data$2<-[2,3,4,5,67,8,9,10]
data$3<-[3,4,5,67,8,9,10]

problems with optimize (again)
Can someone please explain what the $minimum result of the optimize
function actually is?
I'm trying to optimize the function:

template<-stretchWaveTime(ts_template,ampFac)
fit<-calcFit(ts_wave1,template)
return(fit)
}
with

find mean of a list of timeseries
Can someone please give me a clue how to 're'write this so I dont need
to use loops.

For each element in vector do...
Dear R useRs,
I have a vector with positive and negative numbers:
A=c(0,1,2,3,0,4,5)
Now if i-th element in vector A is > 0, then i-th element in vector B
is a+1
else i-th element in vector b=a (or 0)
vector A: 0 1 2 3 0 4 5
vector B: 0 2 3 4 0 5 6
What's the right way to do this. I still have some problems with for and
if statements...
Cheers, Andrej

RODBC and Very long field lengths
I'm having a small problem using RODBC. I'm trying to retrieve a string
from a very long memo field (512*20*9=9360 characters = 74880 bytes) in

It appears that RODBC set a maximum buffer size for a single column of
65535 bytes.
