...for some functions (the main functions). When using R CMD check myPackage, I get a warning message indicating that some of my functions are not documented. How can I get rid of this problem? Of course, I don't want to document every function in the package...

...products, etc...). Therefore, I have to compute these quantities twice which slows down the procedure. How can I get rid of that in a similar way as with 'nlmin' which allows the attribute 'gradient' in the output of the objective function?

Dear all, I very often use the R function "apply", for speedup purposes. I am now also using MATLAB, and would like to use the same kind of function. I have already asked MATLAB people, and the answer is : "vectorize"... but of course, this is not always possible. So, instead of using a FOR loop all the time, I tried using the bsxfun. So you R people, who might also use MATLAB,

...ues from R to C code using the function '.C(...)'. When running my code, I get an error since C does not recognize -Inf and Inf values. Of course, I could use instead a very low (or high) number, but I was wondering whether a more elegant solution exists.

Dear all, I would like to create a math-type label like this one: c(expression(theta[1]), expression(theta[2]), ..., expression(theta[N])) How can I do that in an automatic way (i.e., for any dimension N). I tried with a "for" loop, but also need to used substitute I guess. Any idea? Thanks a lot, David

Dear all, Imagine that you have a small LAN with two computers. I would like to run R on both, and possible to run computations from one computer to the other one. TCP IP protocole would be preferable. Which package would you use for that? I would be very glad if you could also provide me with some lines of code, e.g., create a matrix X in computer 1, transfer its value to the second computer,

Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems
