...s amply documented, but I confess that I have a rather difficult time with much of the documentation on writing packages. Apologies for the elementary level of these questions, and thanks in advance for your help! ~Dan Rabosky Dan Rabosky Department of Ecology and Evolutionary Biology 237 Corson Hall Cornell University Ithaca, NY14853-2701 USA 607 254 4262 (office) 607 592 4636 (cell) DLR32 at cornell.edu web: http://www.birds.cornell.edu/evb/Graduates_Dan.htm

...program to execute (typically done by simply entering " \n " after manually entering parameters). -Enter name of output file. -Close program. Any advice will be greatly appreciated!

...potential problem with this approach is that - should an error occur within a private function, it may be very difficult for the user to decipher the nature of the problem.

Hello, i have a little problem with R and i hope you can help me. I want to use splines to estimate a function but i want to force the interpolation to be monotone. Is this possible with R ? Thank you, Rémi. --------------------------------- [[alternative HTML version deleted]]

Dear all, Has anyone worked on coding for calculating Lyapunov Exponent for a time series data? or any package is available for computing Lyapunov? Please advice and many thanks in advance. Catherine X Wang

I am using "maps". I am running the following code to get this list of all the counties: map('county', plot=FALSE)$names In the output, all counties have first the state listed and then, after a comma, the name of the county. However, county # 2395 (State = south dakota) has no county name. Anyone knows what this county is? Thank you! -- Dimitri Liakhovitski

R-users -- I would be interested in tools in R to fit the following gam model: logit(p) = a + f(x1) + f(x2) + f(x1,x2), where f(x1,x2) defines a surface. I have looked into the mgcv library, but it seems only to fit models of the form: logit(p) = a + f(x1) + f(x2) Any ideas? Cheers, Dan =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Dan Powers Associate Professor,

...which I dynamically create variables in lists, without initializing them in some fashion? This approach worked fine until I noticed this issue with variables having similar names.

...can do with matrix objects? Or some other way to avoid the twofold speed hit in moving to 1.9? I've tried using the Rblas.dll for AthlonXP on CRAN, and it doesn't help.

R help list subscribers, I am a new user of R. I am attempting to use R to explore a set of equations specifying the dynamics of a three trophic level food chain. I have put together this code for the function that is to be evaluted by LSODA. My equations Rprime, Cprime, and Pprime are meant to describe the actual equation of the derivative. When I run LSODA, I do not get the output that
