Hello,
Is there an iterative reweighting option in LOESS function from modreg
package to perform robust fitting in the presence of outliers in the data ?
Thanks in advance.

Dear all,
I fit independent GLMs for a 2x2 factorial problem on the data matrix of
size 9500 x 12 (genes x arrays) and get 9500 observed t-values using the
apply() function. Now, I wish to get the permutated p-values. Therefore
I random sample the class labels and perform the glm fitting to get

No so: it's through the family argument to loess: `iterations' sets how
many iterations *when* robust fitting is selected.

The problem in this case is that the RPM file is corrupted. Try

To check if the package has been corrupted type:

Dear all,
I've seen that there are some maps, or at least costlines in R. The oz
package is the map of Autralia and in the fields package there is a US
map and a world map. This world map allows to select smaller sections

You can try RarcInfo, which has it's homepage at

there is a link to free data in the section related resources.

Can we do anything to speed it up?

Thanks for all the helpful decimal point information. I implemented it,
