Dear R-users, I have recently discovered the languageR package and its aovlmer.fnc which offers a very slick way to test fixed effects hypotheses in lmer models using mcmc. However, the R help page for aovlmer.fnc states that...

Hi All, I need to sample a vector ("old"), with replacement, up to the point where my vector of samples ("new") sums to a predefined value ("target"), shortening the last sample if necessary so that the total sum ("newsum") of...

Dear All, I need to produce a multi-panel plot where: 1) groups within panels receive distinct symbols; 2) a linear regression is fit to the entire panel, not the individual groups; 3) a common abline is plotted in each...

Dear R-Helpers, Can anyone please help me to interpret warning messages from zeroinfl (package pscl) while fitting a zero inflated negative binomial model? The console reports convergence and the parameters seam reasonable, but these <<Warning messages: 1: algorithm did...

Great! Thanks to both Paul and Deepayan for these efficient approaches! -Dan Deepayan Sarkar wrote: > On 11/6/06, Paul Murrell <p.murrell at auckland.ac.nz> wrote: >> Hi >> >> >> Deepayan Sarkar wrote: >> > On 11/6/06, Daniel E. Bunker <deb37...

Dear R users, About a year ago Deepayan offered a suggestion to incorporate error bars into a dotplot using the singer data as an example <<http://finzi.psych.upenn.edu/R/Rhelp02a/archive/63875.html>>. When I try to utilize...

# Hi All, # # I need to solve a somewhat complex equation at many parameter values for # a number of different parameters. # A simplified version of the equation is: 0= (d1/(h1^2))-(h2*(d2^2)) # I'd like to solve it...

Dear R Users, I am trying to write a wrapper around summarize and xYplot from Hmisc and am having trouble understanding how to pass arguments from the function I am writing to the nested functions. There must be a way...

Dear Deepayan and Sundar, Thank you so much for your help with this. However, I may have phrased my problem too specifically, assuming that *in general* I could apply your response to all Lattice graphics. What I need is a...

Hi All, I am writing a simulation that examines the effects of species extinctions on ecological communties by sequentially removing individuals of a given species (sometimes using weighted probabilities) and replacing the lost individuals with species identities randomly sampled from...

Dear All, I am hoping to implement a barchart using trellis graphics where all elements have a line width of 2. Using trellis.par.set(), I am able to make most elements lwd=2, but not all. In particular, the...

Duncan, Thanks for your reply. Here is a simplified version. What I really want to be able to do is summarize same data (using 'summarize') and pass those results to 'xYplot' for plotting, all in one wrapper. For this example...
