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 opera...

...o here is a list of my doubts: 1) I am very confused on how the lang 1 2 3 4 ... set of functions work. I haven't found any relevant documentation explaining it clearly. I have a vague idea but still I cannot understand how I would evaluate an R expression like Covariance <- round(cov(100 * SWX.RET), digits = 4) using lang, install and R_tryEval. 2) What exactly does install do? 3) I wrote the following code: #include <Rinternals.h> #include <Rembedded.h> int main (int argc, char** argv) { SEXP e,val; int errorOccurred; Rf_initEmbeddedR(argc, argv); // l...

Hi, I am working on R 2.15.2 on Win. 7. I am trying to run some simple commends. >class(SWX.RET) # SWX.RET is a data file that has been loaded. But, I cannot see the expected output. I have deselected "buffered output". Still it does not work. Any help will be appreciated. Thanks [[alternative HTML version deleted]]

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 encapsulat...

The problem is easily reproduced: # mkdir ~/foo # continusync ~/foo root@remotehost:~/foo & # vi ~/foo/bar.txt This generates an immediate exit from continusync with the following 3 messages: "rsync: link_stat "/root/foo/.bar.txt.swx" failed: No such file or directory (2) rsync error: some files could not be transferred (code 23) at main.c(977) [sender=2.6.9] [1]+ Broken pipe continusync ~/foo root@remotehost:~/foo" This is using slackware 11, on which vi is a link to vim version 7.0.

Hi I am unable to try out examples from the Rmetrics Ebook from the R command prompt. Below is an example of what happens: > Covariance<-cov(SWX.RET) Error in cov.timeSeries(SWX.RET) : no slot of name "Data" for this object of class "timeSeries" I have loaded Rmetrics and fPortfolio using the library function but still I get these errors. However, if I embed the R code into a C program like below it works. Why is th...

Grasping a full understanding of setting default Users, Groups and Masks has alluded me over the years, but now I find myself in a situation where manually "setting" the file/directory attributes is becoming a pain. I understand the fundamentals of the file attributes, though from time to time I have to review the "sticky bit"; what I do not understand is where/how the
