I'm trying to get a reference to this object in C SWX.RET[1:6,c("SBI,"SPI","SII")] While i am able to access and use a plain SWX.RET object, I'm getting confused on how to create an object with the array subscripts like above. Here is what I tried to do. It doesn't work because "[" is obviously not an operation or function on SWX.RET. So how do I

Hi I think I have asked these questions earlier, but I been able to find answers from the documentation (which I found poorly written in several places). Will someone be kind enough to give me answers and enlighten me? (as in explain with CODE?) I want to embed R in my application and use the fPortfolio package for carrying out risk management computations. Right now I'm reading the Rmetrics

I am porting SWX (swxformat.org) to Ruby. It''s a data exchange format that assembles data structures into native SWF bytecode. Here''s my dilemma: The original SWX implementation (PHP) tests a lot of methods that wouldn''t be included in the public API (if PHP properly supported encapsulation that is).

I am experimenting with Matt McCutchen's excellent continusync script, and I'm having an issue. (My copy of continusync has been modified from the original http://mattmccutchen.net/utils/continusync by adding this @ line 227: <$fromInwt>; as suggested by Matt.) The problem is easily reproduced: # mkdir ~/foo # continusync ~/foo root@remotehost:~/foo & # vi

However, if I embed the R
