Hello, I have a bit of a tricky puzzle with trying to implement a logit model as described in a paper. The particular paper is on horseracing and they explain a model that is a logit trained "per race", yet somehow the coefficients are combined across all the training races to come up with a final set of coefficients. My understanding is that they maximize log likelihood across the

...rix.type = "edgelist") # Plot the network: gplot(dat.edg, displaylabels = TRUE, label.cex = 0.9, arrowhead.cex = 0.9, vertex.col = "red") Is there any way you know of scaleing the size of the nodes in the graph? I was hoping to scale the nodes according to their individual betweeness score. Betweenness can be calculated for each node in the example above, using: betweenness (dat.edg) # Giving the output: [1] 4 0 3 0 0 0 0 0 3 0 Hope you can help ... many thanks, tom Thomas Rawdon, Incursion Investigator (Animals) Investigation and Diagnostic Centre | Investigation R...

Hi all, I've been having some trouble with times in regards to daylight savings in R version 2.8.1.

I'm also finding that if I open a R workspace from version 6.2.2,the datetimes are

Just when I thought I couldn't be wrong, I was wrong. We have woodpeckers that drill into the arial telephone cables, and water seeps through the holes and partially grounds the tip and/or ring wires causing hum. I thought the hum/buz on my lines was a telco problem. The Qwest HQ noise team assures me that my lines are within spec. Sure enough, when I listen on the test set the lines

Im trying to ascertain whether or not the facilities of R are sufficient for solving an optimization problem I've come accross. Because of my limited experience with R, I would greatly appreciate some feedback from more frequent users. The problem can be delineated as such: A utility function, we shall call g is a function of x, n ... g(x,n). g has the properties: n > 0, x lies on the
