...and continually either crashes, behaves very erratically (nodes disappearing when I modify edges), nor is it clear from the UI how one outputs a new graph, nor how one even accesses many graph attributes. This may be my own ignorance on the latter. Do you have any suggestions?

...w to alter a global variable from within a function. For example m<-3 a<-function(x) m<-4 a(3) m shows that m is still 3 at the end of it all. With the code above, how could I modify the function a to actually set m to whatever value I wanted globally?

Given that this is true either for lm, glm, or lmer objects, I'm guessing there's a more general issue here that I'm missing. Any pointers?

...t; not found I'm uncertain as to what this means, as Slip most certainly is there (yes, I checked) - any pointers, or pointers about syntax for this as a general topic. And while I'm on it, is there a way to fit models with random effects using least squares instead of REML? Thanks! -Jarrett

...nlist(simulate(model.1)) sim.model.2<-update(model.2, sim.data~.) Error in x[[3]] : object is not subsettable Now, the following sim.model.1<-update(model.1, sim.data~.) appears to work just fine. Does anyone know why update won't work, and is there something I can do about this? -Jarrett

...post-hoc (as recommended by Day and Quinn, 1989, Ecological Monographs). I can't seem to find any methods in the base stats package that implement this post-hoc. Is there a good package of post-hoc methods out there, or has someone written a method for Ryan's Q previously? Thanks! -Jarrett

...from R are much cleaner, and more easily integrated into my analyses. Is there any good way to diagram a hierarchical network in R, either with the sna library or otherwise? It strikes me that at least the Netindices package can calculate trophic levels.

...be due to the unbalanced nature of the dataset (some studies having T1 and T2, some having multiple measures of T1 and T2).

I had a question about scan in R. For better code readability, I would like to have lines in the block of data to be scanned that are commented - not just lines that have a comment at the end. For example #age, weight, height 33,128,65 34,56,155 instead of having to do something like 33,128,65 #age, weight, height 34,56,155 Is this at all possible?

...of the line, and the slope and intercept of the second half of the regression is not 0. Is there either a package that exists that will allow me to estimate such a model, or a function that I can use for optim or nlm (I admit, I am a rank novice at coding such functions). Thanks so much! -Jarrett

Does anybody have any tuning tips for a samba 3.0.23 server that is acting as a PDC with ldap backend and file server.

Does R somehow allow harmonious help functionality in such cases (by, for example, maintaining separate copies of packages.html for different users)? Suggestions? Thanks.
