I'd like to compare two models which were fitted using gls, however I'm
having trouble interpreting the results of gls. If any of you could offer
me some advice, I'd greatly appreciate it.
Short explanation of models: These two models have the same fixed-effects

Hello,
I am fairly new to R programming and am stuck with the following problem.
I am trying to read in multiple files (see attached file or at end of
email), the files all have the same general header information and
different precipitation (avgppt) and area (areasqmi) values. Some times
dear R experts: I am trying to plot an empirical likelihood function in 3d.
The values are not over a regular grid---I just searched the likelihood
function to find the optimal value, and then computed a few values around
it. (each point in the likelihood function takes a very long time to
Hi,
If any body can help me regarding a basic problem using R?

I would put the data into a 'long' instead of 'wide' format since you
say you have files of different lengths. I took you data and
replicated it 3 time and changed the file name for the duration:
fileNames - Sys.glob('/da_zone*') # files to process
result - lapply(fileNames, function(.file){

Hi All,
I would like to run a linear model where the response is the duration of
relief in days and the regressor is the drug dosage in mg. Then I would like
compute the predicted values of the duration of relief from the model and
merge it into the original data. I am not sure how the merge
Dear fellow R-users,
Say we have a matrix x, defined as follows
set.seed(50)
x - matrix(rbinom(100*5,1, p=0.75),nrow=100, ncol=5)
Now the interpretation of x is that each for of x is actually a sequence of
length 5, and i would like to transform x in such a way that I can describe the
