Dear R users, I'm looking for a test of bimodality in order to make some decisions about how to procede with an analysis algorithm. I have not come across any such tests in my readings and discussions apart from the Rao which appears to be applicable to cyclic data. The data I'm interested in characterizing as uni- or bimodal are frequency x amplitude spectra of consonant speech sounds,

Hi Everyone, Does anyone know how to take the output of a 2D fft() and shift the DC component to the center? Is there a function that does that? if you know, please send me an email. thanks for any help! brad __________________________________________________ . http://im.yahoo.com -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

According to the CRAN contributed packages page, the license for "KernSmooth" is *not* GPL. It is listed as "License: Unlimited distribution (from Dr Wand)." Are there any restrictions on this of any kind? Is there some written license document similar to the GPL license? The reason I'm asking is that the legal beagles in the company I work for are extremely paranoid about

I was using the hist() function to create a frequency table of some network traffic data. The range in values is rather large, from 0 till just under 10e12. Calling hist(x, breaks=c(0,1000,1e6,1e9,1e12),plot=F,freq=T) causes hist() to return : $breaks [1] -1.0000e+05 1.0100e+05 1.1000e+06 1.0001e+09 1.0000e+12 Is this recalculation of the breaks by hist() intended?

When I try to go to http://cran.us.r-project.org I get sent to a location called "domains 4 sale" or something of that ilk, indicating that some "URL scavenger" has flagged it as expired. Has something happened, or is it just wishful thinking on some scavenger's part that the URL is no longer pointing to the US CRAN mirror? Try this link:

Is there any way to control the format of the axis label numbers on a plot? More specifically, I have some plots that get axes with label numbers in exponential format, and I'd like to change that to non-exponential. Thanks!! -- M.

Dear all, I have a lot plot graphs and i would like to save them. One solution is to use the grab function with xv. But it is tedious.... So is there a R function that can save automatically the result of a plot in a gif or ps or bmp file Thanks Olivier -- -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- Olivier MARTIN phone: (33) 04 76 61 53 55 Projet IS2

Hi All, Briefly, I belong to a fisheries research group. At this time I'm working on my PhD and I'm looking for some statistical help. My mathematical and statistical skills are still scarce, I've gathered many different types of data (landings, climate and upwelling indexes, rains, etc) and I wonder about what kind of statistical procedure use with them. I'm a little confused

I'm trying to do a modulus operator in R-1.2.2 on Windows -- specific version: R : Copyright 2001, The R Development Core Team Version 1.2.2 Patched (2001-03-22) Here's what the R language manual says: "R contains a number of operators. They are listed in the table below. [snip] % Modulus, binary" Here's what happens on the R console: > records <- 100000 >

I observed the same behavior as Edward this morning with R-1.2.2 on Red Hat Linux 7.0. There appears to be a problem with the library in netpbm-9.5-5, even after hunting down the missing shhopt.h that pbmplus.h is looking for. I worked around the problem by compiling e1071 without pbm support (moved pbm.c to pbm.c.bak). Matt Matthew R. Nelson, Ph.D. Director, Information Systems Esperion

I have a Red Hat 7.0 system, plus glibc-2.2 and gcc-2.96.69.

Hello, I have a problem. I have to read a HUGE file which has to be line processed, so I would like to use scan like p <- scan(pfile,what=c(0,0,0,"",0,""),nlines=1) but it continues to read the first line, so I have to add a skip and increment the skip after each read. It takes forever to read a test file of 1 Mb, the real one is in 60's Mb Is there a way to read line

I need to completely remove row.names from a dataframe. Are there other ways to remove them (and not anything else) besides: mydataframe<-data.frame(mydataframe, row.names=NULL) I realize that this doesn't really remove the row.names; it merely replaces the current row.names vector with the numbers 1..nrow (in quotes). ===================== Dr. Marc R.

I'm running Windows NT4. Rcmd does not seen to read the command line. Rterm and other things work well. For example "Rcmd check --help" fails with the command interpreter trying to find a program or file called "check."

Hi, I have recently installed R-1.2.2 for windows (16MB RAM, P-166) and I getting the following message after processing my data (6 variables and 1200 observations): >Error: cannot allocate vector of size 4 Kb >In addition: Warning message: >Reached total allocation of 15Mb: see help(memory.size) Then, the program close. With the last version, 1.1.1 (I think) I didn't have this

Greetings, I downloaded R for my mac from software, R binaries, rm123, base and then downloaded "rm123.sit.hqx" Now, when I open R and try to type anything in the blank, I get a message that I need CarbonLib 1.20 or newer to run R. Please tell me what this means and where to go to get it. By the way, when I type anything in and recieve the error message, R will then refuse to close
