C# DLL Library
Good afternoon everybody,
I am sorry, this question might look trivial to some of you, but I read
quite a lot of stuff about package creation and I would like a bit of you
advices.
I would like to develop a core library which I will be using both from R and
from C#.
I read that it was possible to import DLL to R.
The thing is, I am not sure that the DLL created with C# will be compatible.

How is the relation between Frequency and Counts in hist/density defined?
Hi all,
I'm looking to add a "density" smoother on top of a hist when Freq=T.
In order to do this I can use the relation between count and density, but I
would like to know if there is a way for me to predict it upfront.
Here is an example:
set.seed(242)
z = rnorm(30)
hist_z <- hist(z)
hist_z$counts / hist_z$density # the relation is 15
# why is this 15 ??
# So I can now do:

String search: Return "closest" match
Hi,
I have to match names where names can be recorded with errors or additions.
Now I am searching for a string search function which returns always the "closest" match. E.g. searching for "Washington" it should return only Washington but not Washington, D.C. But it also could be that the list contains only "Hamburg" but the record I am searching for is

excluding on element from a list
Dear List,
I am making a list of all the files in a folder and I want to exclude
one file called "proj.current". This is the 31st file in a folder.
Currently I use the command:
tdirs <- list.files(pattern="proj.")[-31]
However I would like to exclude it based on its name and not the position.
Any advice would be useful.
Thanks,
Daisy

warning with hist
Hello everybody,
I don't understand the warning I get when executing the following code:
x <- rnorm(100)
h <- hist(x, plot= FALSE, freq = FALSE)
If I don't use the plot-argument, I don't get a warning...
Any explanations for me?

I have a request...
Can I call R functions/routines from C# or C++? If so, how do I do this? Do I need to have some knowledge on DLL to do this?

Powell's unconstrained derivative-free nonlinear least squares routine, VA05AD
I have used Mike Powell's optimization routine (VA05AD) from the Harwell Subroutine Library (HSL) for more than 20 years. It is no exaggeration to say that it has helped make my career (thanks Mike). I recently learned that I am not alone in this respect - apparently it still has a loyal following in all sorts of fields!
It is an exceedingly fine piece of software - fast, reliable and easy to

Combine Values into a Vector or List
Hi all,
I have the following
x1<-paste("A", 1:6, sep = "")
x2<- round(rgamma(6,2,1))
x3<-paste("B", 1:6, sep = "")
x4<- round(rgamma(6,2,1))
data1 <- data.frame(x1,x2,x3,x4)
I would like to get
data2 <- c(A1=4, A2=1, A3=0,...)
Is there any standard for such a case?
Thank you very much in advance,

using speex in C#
You could compile Speex as a DLL (see libspeex_dynamic.dsp) and use PInvoke.
http://en.wikipedia.org/wiki/PInvoke
Note that Speex will still be executing as unmanaged code and your program
will have the added dependency of the native Speex DLL.
It appears that someone created a "Speex.NET" based on JSpeex, but I
didn't find any useful info on it. You may want to search for this
