Well, that's very general (did you mean recursive functions in R or C or what?). Recursion is not particularly slow in R, and you are limited to a depth of a most a few thousand.

[R] finding method file?
dear R wizards: I am trying to determine how to determine (no further recursion) where a built-in function is defined. In particular, I have decided I am going to add sd() to the existing basic summary function, rather than try to rewrite my own summary() function from scratch. So, I just installed R-2.2.1 (via gentoo; eventually I will figure out how to get atlas/sse/sse2 working on amd64, too! PS: [a] how can I determine whether a running S installation uses sse2, sse, and atlas? [b] does atlas use sse2; [c] are there now modern graphics processor routines that might speed up R, too? ok, all of these are irrelevant sidequestions). then, I did a summary [not informative about which file it is defined in] ok, easy. Just grep. back on the unix line, # grep -r '1st Qu' /usr/lib/R which should look for this fairly unique string. to my surprise, it was only found in R-intro.html. so, how would I go about looking for where R defines functions? or has this becomes so deeply wired into fortran/C in later versions that it can no longer be changed? help/advice as always appreciated. sincerely, /ivo welch __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Re: [R] mutual information for two time series
Have you first done more traditional analyses like normal probability
plots and simple ARIMA models of each series individually? In
particular, have you tried this after transforming your two series to
the mean and difference between the two series? The mean series should
relate to what's happening in both hemispheres, while the difference
should relate more to differences.
Regarding KernSmooth, I didn't see in its documentation any mention
of time series. Virtually all of the traditional distributional
analyses assume independence. Almost no time series are statistically
independent. I'd be particularly skeptical about any suggestions of
non-normality among time series with 128 observations per second.
I've skimmed through your code, but I've never used KernSmooth, so I
can't comment further. If you had included a short, self-contained,
reproducible example, I might have been able to say more.
hope this helps.

Hi I hope this is going to the right place. I am trying to write a program
which uses KernSmooth library to estimate mutual information between two

summing across one row of the matrix to get p(value is in bin x) and summing
across the columns to get p(value is in y), and just taking the value for
the density at x,y to get the joint probability p(x,y), then just applying
formulas for mutual information…. I know it’s kludgy… does anyone have any
idea as to what I’ve done wrong?
The data is EEG sampled at 128hz from the left hemisphere (C3) and right
hemisphere of the brain during neurofeedback sessions and enters via a
bivariate time series to datin, and lmax is the maximum lag to measure the
mutual information at. I hope to use it to set up optimal bivariate

(commandArgs() is not the answer, either.) And I did also not see it under the FAQ in the R programming section...and may I suggest this for the faq? I think the answer to this is platform dependent. In Windows, the answer is: you can't. The command line gets eaten by Rcmd.exe and isn't passed to R. But you can still get it from the system. On XP Pro (maybe other Windows systems too?) place this in a.r out - system(wmic /output:stdout process, intern = TRUE) out - sapply(out, function(x) substr(x, 1, nchar(x)-1)) print(strsplit(grep(rcmd.exe.*batch, tolower(out), value = TRUE), *)[[1]][4]) and then at the command line type: Rcmd BATCH a.r and it will print out a.r __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

[R] (no subject)
Would greatly appreciate some help. During R installation, we are getting the following error message: '-lX11 is not found...' when doing gcc compile. The machine is an Opteron 64. I did some looking around and found similar problems in which the advise was: a. make sure SDK is installed b. another had to modify the variable PKG_CONFIG_PATH Does anyone have some suggestions?

Re: [R] head function
The functions 'page()', 'head()' and 'tail()' let you look at a dataframe or array without actually opening the file. They are equivalent to 'less', 'more' and 'tail' in UNIX.

You get to see the head (or beginning section) of a vector, data frame or whatever, which gives you a bit of an idea what it looks like. It is an idea which comes from the unix operating system commands head and tail which were particularly useful in examining files in the days before gui editors and such fancy new-fangled things.
