Hi Diego,
It depends on your what your research questions are. You haven't told us :)
For example, if you wanted to know whether (a) the environmental
distance between lakes is correlated with spatial distance and (b) if
the relationship changes over time you might do a series of Mantel
tests. T

use different algorighms, and this allows aov, for example, to handle some

I've been attempting to fit the data below with an inverse gamma

a Chi-Sqr goodness-of-fit roughly 40% better than with a log-normal fit.
For any given pre-specified gene or short list of genes, yes the Cox
model works fine. Two important caveats:
1. Remeber the rule of thumb for a Cox model of 20 events per variable
(not n=20). Many microarray studies will have very marginal sample
size.
2. If you are looking at many genes the

Beyond this, there seems to be an increasing trend towards

You find the prediction error as the var1.var column in your result
object, i.e., y in your script. For plotting:
spplot(y, 2)
or
spplot(y,"var1.var")

I agree with you and I will make this ordination. But I also want to

Dear sir, I am extremely sorry for messing up the logic
asking for help w.r.t. my earlier mails
I have tried to explain below what I am looking for.
I have a database (say, currency_rates) storing datewise
currency exchange rates with some base currency XYZ.
currency_rates <- data

Dear Emma,
there is a 'cbind.na', 'rbind.na' and 'data.frame.na' function in my qpcR
package.
library(qpcR)
matLis <- list(matrix(1:4, 2, 2), matrix(1:6, 3, 2),
matrix(2:1, 1, 2))
do.call(cbind.na, matLis)
They are essentially the generic functions extended with an internal fill.

Hello All;
I am writing an R program in the form of a function to find out the summary
statistics for response variable(s) in a data frame.
I need to accept variable names from the data as arguments and use them
inside the function for various tasks. The dataset name is also one of the
arguments
With the ssl.verifypeer = FALSE argument it works:
x = getBinaryURL(dd, ssl.verifypeer = FALSE)

Thanks for the help guys! For my purpose I think that rharlow2's answer, i.e.
the `rowSums' function is the most appropriate since it also takes care of
the NAs.
Best,
Vassilis

Pearl,
The error suggests that there is something wrong with x2, and that there
is a difference between the row names of the coordinates and the data.
If you call
str(x2)
see if the first element of @coords is different from NULL, as this can
cause some problems when cross-validating. If it i

I will wind this thread up with some happy comments. I have indeed
succeeded in constructing an R program to do the same thing as my
Fortran program for an EM algorithm. I have not done timings yet but it
seems to run acceptably fast for my purposes.
The key code to be replaced was the E and t
