pass commands to R language

[mooseo]

Hi,

I'm writing a control program and would like in pass values from sensors to a routine I have written in the R statistical language, then act on the response. Does anyone have experience exchanging data and commands between Labview and R?

thanks,

Hello moose,

   I haven't used the R statistical language, but I have heard that it has a COM interface. Through COM you can interface it in variety of languages and of course LabVIEW is not an exception.

I got an link for using R COM in .NET, it's not that much efficient but you can get some basic idea about interfacing R COM.

Hello,

I am working on writing a data processing package in LabView.  I would like to import R code into Labview to run principal component analysis.  Does anyone know of a way to do this?

Thanks - Mike

I don't know about importing R code into labview, but I came across a couple of very useful webpages that got me going.

The first explains the nuts and bolts of installing the Rcom packages that you will need to use the vi's available on the second page... there you will find a couple of nice vi's that page it quite possible to pass variables and commands to R and get data back.

It takes some fun with strings to get your results back into numbers, but it saved me a lot of time to be able to use R functionality to perform some specialized calculations.

Hope this helps.

Mike,

I'm also interested in doing this.  Did you manage to make it work?  if so, how?

Thanks,

Jolyon
