I wish to perform moving tiles bootstrap resampling on some gridded data meteorological data. I've many years experience with S-Plus, but it has no way to perform a moving-tiles bootstrap. Within R I've learned how to use quadratresample() with the spatstats package and would be happy to simply use empirical percentiles if generating the replicates were fast, but it isn't. So,

Hi. I am running R 1.2.1 on an i686 (dell laptop). I can do simple things like defining vectors, plot, etc... however when I use the function smooth.spline() or demo(lm.glm), I get the following error and it kicks me out of R: /usr/lib/R/bin/R.bin: error while loading shared libraries: /usr/lib/R/bin/R.bin: symbol __sysconf, version GLIBC_2.2 not defined in file libc.so.6 with link time

Hello, I think I found a bug in rsync. I checked the TODO and the issues, but I didn't find any reference to it. It seems, that rsync goofes up, if you rename a directory and then create a symlink with the old name to the new location. Below is a simple example how to do it. ------------------------------------------------------------------------------ [ptriller] elmore:~/test > ls

I was wondering if someone could help me with an autocomplete problem. I have the autocomplete div receiving a <UL> that looks like: <ul> <li>Name<br>Email</li> </ul> When the user hits enter and the value is filled into the text field it''s putting both the name and email in the field. I just want the name. Funny this works in Firefox but not IE. I

I would like to plot multiple random walks onto the same graph.

When using the autocompleter and scrolling through options, if you press the up arrow key the input field cursor moves backward. Some of my users have reported that they find this very distracting. Does anyone know why this happens, or where in the code I could fix it? Steps to recreate: 1. Go to http://demo.script.aculo.us/ajax/autocompleter 2. Type in a letter (or two or three) 3. Arrow down

Hi, I have been using maxLik to do some MLE of Geometric Brownian Motion Process and everything has been going fine, but know I have tried to do it with jumps. I have create a vector of jumps and then added this into my log-likelihood equation, know I am getting a message: NA in the initial gradient My codes is hear # n<-length(combinedlr) j<-c(1,2,3,4,5,6,7,8,9,10)

Hello all, could anyone explain the exact meaning of parameter nproc? Why different values of nproc give so different critical values, i.e. meanL2BB$computeCritval(0.05,nproc=3) [1] 0.9984853 meanL2BB$computeCritval(0.05,nproc=1) [1] 0.4594827 The strucchange-package description gives "integer specifying for which number of processes Brownian motions should be simulated" - do I need

Is there a package that will allow me to fit Brownian motion and Ornstein?Uhlenbeck models of evolution for discrete traits? I know that geiger and ouch have commands for fitting these models for continuous traits, but these aren't suitable for discrete trait evolution, correct? -- View this message in context:

How can I slow/speed up the combo effects? Thanks

Hi all, Firstly is there a way to search the archives? Second I was wondering if there is a way to implement a scrollbar on the list that occurs when you use autocomplete. I have some lists that are very long so I would like to shorten them but still have all the options.

Has anyone been able to make scrollable results for an autocompleter? Thanks!

Dear R Helpers, I have searched for any R package or code for simulating multivariate fractional Brownian motion (mFBM) or multivariate fractional Gaussian noise (mFGN) when a covariance matrix are given. Unfortunately, I could not find such a package or code. Can you suggest any solution for multivariate FBM and FGN simulation? Thank you for your help. Best Regards, Ryan ----- Wonsang You

Any ideas how I can submit say, a person ID instead of the person''s name on an autocompleter input field? Surely this is a common need. Thanks! Daniel

Hi: I was wondering whether I can find some help for computer simulation of stochastic processes (e.g. Brownian motion), for pedagogicl/instructional purposes. Any help would be appreciated. thanks, Ravi.

Hi, I'm writing a short course tutorial to Browninan Motion/ Langevin Equation. At the end of the theory section I wanted to add a short GNU R example, so the students can play a little around. I already looked in the MASS book (by Venables and Ripley) but I couldn't find any Brownian Motion/ Langevin Equation package. Are there any good packages or tutorials available which cover R and

Hi all, I am not sure if this feature exists in the R-console command line prompt: In Matlab, if I want to enter a command which is similar to what I have entered before, I can enter a few prefix, then press "->", the previous command that matches with this prefix will then appear on this command line, and it saves a lot of our time. For example: > abline(lm(new~old)) >

Hi list, I'm trying to generate fractional brownian surfaces in R. [A detailed description with respect to various techniques to generating these neutral landscapes has been described by Timothy Keitt (spectral representation of neutral landscapes, Landscape Ecology, 2000) and probably various other authours.] Are there any packages that deal with this or related items?
