glim and gls
Hello, I would like to know if there is any package that allow us to fit Generalized Linear Models via Maximum Likelihood and Linear Models using Generalized Least Squarse in R as the functions glim and gls, respectively, from S-Plus. Also, anybody know if there is any package that fit Log-Linear Models using Generalized Least Squares? Any help will be very useful. Thanks, -- Frederico

Generalized Estimating Functions
Hi, I'm trying to fit a marginal model via GEE but I'm getting strange results and few problems. If I set the working correlation as exchangeable I'm getting the same fitting when I set as independent. Comparing to SAS results it shouldn't happen. If I try to use another working correlation (like AR-M or stat_M_dep), R just exits without giving any error message. Another doubt

How does nlm work?
Dear R users, I have looked in the reference Schnabel, R. B., Koontz, J. E. and Weiss, B. E. (1985) A modular system of algorithms for unconstrained minimization. _ACM Trans. Math. Software_, *11*, 419-440. cited in the nlm help. This article says that the algorithm permits the use of step selection (line search, dogleg and optimal step), analytic or finite diference gradient

evaluate a string
Hello together i want to execute different commands that are saved in strings (eg: "d <- 4+7" and some more complicated things). How can i execute/evaluate them. I know i could save them to a temp-file a read this with source. But is there a way without a file in the middle? I know also the 'assign' command but I think it would only the simply cases. thanks and gruess joerg

cluster of points

For example aggregate all the points that stand within a distance of 40 from each other. I've tried using "nncluster" from the package nnclust, but the results are not correct, for some

List and Column Names in a Function?
In this simple function, how can I pass strings for index and column names to the function? I've posted this type of question before and received no response. Maybe this example will be easier to understand and troubleshoot. ds <- function(myds, vec) {myds[[vec]]*2} ds1 <- c(X=list(1:10), Y=list(11:20)) ds(get("ds1"),get("Y")) khobson at odot.org Kenneth Ray
