Call R program from C++ code
Hi All:
I'm developing an application program using C++. From my C++
code, I would call some R program I have written. I' wondering if R provide
some compiler that can compile R program into executable program. I searched
R-help, there are a lot of posts talking about writing C++ code in R
program, but few about calling R from C++.
I might be wrong that R

Fractional brownian motion
Dear All;
I have used fbmSim to simulate a fbm sequence, however, when I tried to
estimate the Hurst effect, none of the nine procedures gave me an answer
close enough to the real value, which is 0.5 (n=1000). So, would you please
advice,
1. which is the best method to estimate the H among the 9 mehods, R/S,
higuchi or Whittle?
2. how to choose the levels (default=50), minnpts, cutoff values or

is that possible to graph 4 dimention plot
Suppose there are 4 variables
d is a function of a , b and c
I want to know how a, b and c change will make d change
It will be straightforward to see it if we can graph the d surface
if d is only a function of a and b, I can use 'persp' to see the surface of
d. I can easily see at what values of a and b, d will get the maxium or
minium or multiple modes, etc
But for 4 dimention graph,

anyone konw Polyclass package in R?
Hi everyone:
Polyclass is a polytomous logistic regression model using
linear splines and their tensor products. It provides estimates for
conditional class probabilities which can then be used to predict class
labels. I know there is Polyclass package in S-plus. So I'm wondering if
there is a corresponding package in R? I have been searching for it for
quite a while, but still

Just to throw it out there, there's also XCP-NG which is a rebranded (w/o

how to preserve trained model in LDA?
Hi all:
I'm developing an application in which I use standard data to
train the model in LDA and use the trained model to predict on test data. I
can't train the model every time when I do prediction. So I need to save the
trained model onto disk after the first training. Does anybody have idea
about this? You help is highly appreciated.

System Requirements for Samba?
Hi Rob,
I'm not sure you will get much pleasure out of VirtualBox on that
hardware. It sits completely on top of the OS and it will grab most of
the resources, even hogging from the OS. And it will run very hot. The
Xen hypervisor (incl. XenServer, XCP-NG) is very resource efficient and
with Linux guests (PV or PVHVM), it will run very smoothly. The same
applies to KVM. My FX-6300 box

Max calls & IAX2 trunking
Is it possible to increment a call group (Max_Calls) from one server to
the next server?
I'm trying to set a maximum call limit between two facilities (2
Asterisk servers) using Set Group. I want the limit to be set at 4.
The problem with the code that I have in place, is it allows for 4 on
each server, hence the possibility of maxium of 8 concurrent calls.

if ... problem with compound instructions
I am having problems with the 'if' syntax.
I have an n x 4 matrix, X say. The first two columns hold x, y values and
I am attempting to fill the second two columns with the quadrant in which
the datapoint (x, y) is and with the heading angle.
So I have two problems
1) how to do this elegantly (at which I've failed as I can't seem to
vectorize the problem) and

ifelse on data frames
[Using R 2.2.0 on Windows XP; OK, OK, I will update soon!]
I have noticed some undesirable behaviour when applying
ifelse to a data frame. Here is my code:

A <- matrix(A,nrow=2,ncol=5,byrow=T)
A == 0
ifelse(A==0,0,-A*log(A))
A <- as.data.frame(A)
