similar to: outer not applying a constant function

> Or is this a bad idea? I don't like the proposal. I have seen code like the following (in fact, I have written such code, where I had forgotten a function was not vectorized) where the error would have been discovered much later if outer() didn't catch it. > outer(1:3, 11:13, sum) Error in outer(1:3, 11:13, sum) : dims [product 9] do not match the length of object [1]

Hi, I posted this message earlier in "Rmetrics" and I don't know whether I posted in the wrong place, so I'm posting it again in Rhelp. I have a function in x and y and let's call it f(x,y). I need to get the Hessian matrix. i.e I need (d^2f/dx^2), (d^2f/dxdy), (d^2f/dydx), (d^2f/dy^2).I can get these using the D function. now I need to evaluste the hessian matrix for

Hi,  I want to do regression in each group. I made the group the following way. Now I want to run regression in each of the three groups.. Suppose , x<-c(0.5578196,6.5411662,13.2728619,2.0217271,6.7216176,3.37220617,2.5773252,7.2600583,15.3731026,3.4140288,8.1335874,     15..6476637,4.3014084,9.1224379,18.5605355,4.7448394,11.9296663,18.5866354,12.3797674,18.7572812,2.70433816,2.88924220,

I am writing a Gibbs sampler. I think it is outputting some of what I want, in that I am getting vector of several thousand values (but not 10,000) in a txt file at the end. My question is, is the error message (see below) telling me that it can't output 10,000 values (draws) because of a limitation in my memory, file size, shape etc, or that there is an error in the sampler itself? >

Dear R-users, I am trying to create a multipanel scatter plot which displays weighted regression lines for each subgroup. I am having diffuculty figuring out how the Trellis multipanel plotting functions work, in general. Does someone know where there are some beginners examples on how to create and use panel.xxx functions in conjunction with the xyplot functions? Back to the matter at hand

To use the modify the solution from Tony and I so that you can pass the name of the function, rather than the function itself, like this: x <- 7 fx <- function(y) print(x*y) f <- function(fun, x) { fun <- get(fun) environment(fun) <- environment() do.call("fun",list(3)) } f("fx",2) --- Date: Thu, 11 Mar 2004 08:22:45 +0100 From:

I guess you have had different version(s) or setting(s) in the past, and you can probably fix this by setting perms to same as the new folders.

Hi, I am a new user of R 2.8.1. I use Tinn-R for code editing. I use a windows 2003 system with 1 GB RAM. I am interested to generate dashboard and reports based on data from MS Access. These reports need to be posted on a weekly basis to the web. The reporting interface should provide facilities for "what if" scenarios. Is it possible to interface R analysis results to good open

I have two data sets about lots of companies' stock and fiscal data. One is monthly data with about 144,000 lines, and the other is quaterly with about 56,000. Each data set takes different company code. I need to merge these two together. I read both ask cvs. And the other file with corresponding firm code. Now I have three data sets. return$PERMNO, account$GVKEY. id is the data frames

Assuming '8' = mail, i cannot see anything wrong here... Can you turn on 'mail_debug=yes' and attempt folder deletion, and check logs after that?

Hello, I want to call a function "fx" given by name, where some "global" variables (in the environment of fx) are passed to the function. For compatibility reasons I cannot modify the parameter list of fx and I want to avoid setting variables in the global environment (e.g. via <<-) Is there a way, how to do this? Thomas P. The example: fx <- function(y)

Hi everyone! The fptoui/fptosi instructions are currently specified to return a poison value if the rounded-towards-zero floating point number cannot be represented by the target integer type. The motivation for this behavior is that overflowing float to int casts in C are undefined behavior. However, many newer languages prefer to have a float to integer cast that is well-defined for all input
