I got a table on SQL Server, which has columns EquationId (int) and Formula (varch(900)). I need to select Formula with certain EquationId, for example, Select Formula from OGA_DEV.dbo.Equation where EquationId = 3 I tried to work within RGui using RODBC: > library(RODBC) > conn = odbcConnect("SQL Server") > odbcQuery(conn, "Select Formula from OGA_DEV.dbo.Equation where

I would like to call functions/objects of R from C#.NET environment. I was wondering whether or not it is possible. If yes, could you please give me some suggestions on how to approach it (any examples/documentation on this)? Thanks! -James

Hi SAITAMA Taro, I have been using speex-1.2beta1 dll in our voice application written with C#. In order to use Speex correctly firstly I advice to you examination speexenc and speexdec projects. I have used unsafe code and fixed statements in C#. I have added following method to library and I used that instead of speex_encoder_init simply. void *speex_encoder_init_new(int modeID) { const

Hi, I have read the message below, http://lists.xiph.org/pipermail/speex-dev/2006-October/004924.html and try to use P/Invoke to use speex in C#. This is a part of my code.

Hi. I'd like to build installer for integrate my GUI program for R, R for win and RDCOM. Can the distribution like this be got permission?

Dear All, I am using excel.link package to open and modify Excel files. When I manually open Excel, all my add-ins are loaded without a problem. But when I open Excel using excel.link package, like: xls<-xl.get.excel() xl.workbook.open("MyFile.xlsx") some Excel add-ins are (installed but) not loaded. Since the problem is related to local add-ins at my side, I cannot reproduce the

Hello I am using Duncan Lang's RDCOM Client package (available on omegahat.org) under R 1.7.0 and Windows XP Pro. Is this the right forum for questions about this package? In case it is, here is my question: Instances of COM objects do not seem to terminate as expected, but leave residual processes running. For example, if I try the simple example: E <-

This is a great example how you cannot figure it out after spending two hours troubleshooting, but a few minutes after you post to R-devel, it's just jumps to you (is there a word for this other than "impatient"?); Let me answer my own question. The discrepancy between my sum2() code and the internal code for base::sum() is that the latter uses LDOUBLE = long double (on some system

I need to write a C# program to create and display Cusum chart from any of the packages, spc, qcc or strucchange. Issues: 1-The data resides in a MS SQL Database. The C# program will handle obtaining the data for the requisite types of samples. Assistance needed on: 1-How can I call the cusum capabilities of any of the above packages and pass the data to the cusum function and plot? 2-How

is wrapping c++ any easier? because there is libFLAC++ otherwise, if you only need a certain subset of what FLAC does it might be easier to write a smaller C interface + wrapper implementation, then import that in c#.

This wrapper, I know how to make it in c# (Rewriting stdin and stdout is not possible because I?m discovering one sid after having examined another one) What I?m missing is the api calls (in order) that I need to do to create this connection. Many exports that rpcclient is using are not included in libsmbdlient. I can find the final rpc function, but not the functions to establish the right

Background: I'm working on a web conferencing application hosted in Silverlight, and we desperately need an echo canceller. A while back, someone made a Java port of Speex (JSpeex), which was later ported to C# (CSpeex). However, those are based on an older version of the Speex code, and while they seem to interoperate just fine with the latest official release, they don't have certain

Hola a todos. Se me está plantendo la posibilidad de empezar a aprender C# para hacer algunos programillas (nada grande). El tema es que el otro día en un mail de esta misma lista alguien (lo siento, no recuerdo quien) puso un link a un post en el que se hablaba de la integración entre R y C#. Por supuesto para llegar a poder hacer esto primero tengo que entender las bases de .NET y C#, pero me

This is more of a C# question, but it has to do with the conversion of a data frame using R.NET into an appropriate format to display on a C# DataGridView. My code is as follows (focusing on the button_Click) /private void button_displayDF_Click(object sender, EventArgs e) { REngine engine = REngine.GetInstanceFromID("RDotNet"); DataTable table = new

I'm observing that base::sum(x, na.rm=FALSE) for typeof(x) == "double" is much more time consuming when there are missing values versus when there are not. I'm observing this on both Window and Linux, but it's quite surprising to me. Currently, my main suspect is settings in on how R was built. The second suspect is my brain. I hope that someone can clarify the below
