Hi I implemented the age-structure model in Gove et al (2002) in R, which is a nonlinear statistical model. However running the model in R was very slow. So Dave Fournier suggested to use the AD Model Builder Software package and helped me implement the model there. ADMB was incredibly fast in running the model: While running the model in R took 5-10 minutes, depending on the

I am not new to R, but I am new to .grib files. I am downloading some climate data and I would like to analyze it in R. R has a nice netcdf package, but I don?t see any package available to deal specifically with grib files. I see a few posts from other people using grib files in R. However, I was unclear if they used grib files in a different software program and then imported the data

hi I've used R for many years on windows machines, but have now acquired an Asus eee 1000 linux machine. In order to get the best out of the machine, I used the 'pimpmyeee.sh' script, to get the full KDE desktop. The version of Linux is Xandros, which I believe is a close relative of Debian, but sadly I have only a nodding acquaintance with Linux at present. Naturally I want to

Hello all, I am using R to perform certain calculations on huge amounts of data. In short I need a function that does the mode function, ie returns the most common element. I looked at the mode function in R but it seems to return the type of the data element you give it. Does such a method exist? I have tried googling this to no avail as all the results lead me back to the mode function I do

What is the recommended way of requiring a certain version when loading a package (or, indeed, from R itself)? Perl has the require module version use module version require version use version constructs which is kind of what I am looking for (especially 'use' which is evaluated at compile time), but R seems to have lost the version= argument to require(). The best I have been able

Hello Everyone,   My company purchased S-Plus before it was bought out by Tibco. My understanding is that we own version 7.0 outright.   So far, I've been learning in R but thought I might also try working in S-Plus. My understanding is that S-Plus has some useful extra features. Another potential benefit would be the ability to purchase technical support, which I thought might help me to

Hey, I have a data frame x which consists of say 10 vectors. I essentially want to find out the best fit exponential smoothing for each of the vectors.

I used function points (latitude, longitudes) to transfer them to a per-prepared map. 1- I wonder how I might be able to automatically add codes (1-28) to the map too? 2-Moreover, mostly there are a few codes from the identical coordinates.
