studentized maximum distribution, and the studentized maximum modulus
distribution? Thanks for any help. Kostas

Dear R-users,
I want to fit a linear model with Y as response variable and X a categorical
variable (with 4 categories), with the aim of comparing the basal category of X
(category=1) with category 4. Unfortunately, there is another categorical
variable with 2 categories which interact with x an
Hi,
I am trying to use an R function over a column of data I have in my
excel spreadsheet. I do the following:-
1) assign an object (calling it xaxis) to the data by typing in
=Rput("xaxis",a1:a10), where my data is shown in cells
a1:a10
Now I wish to arrive at the mean of these

Paul,
if you have large graphs the igraph package might help,
it works very well with large sparse graphs. To convert an adjacency
matrix (A) to an igraph graph object (g) you can simply use
library(igraph)
g <- graph.adjacency(A)
and then you can generate layouts with layout.fruchterman.reingol

Hi R users,
I am using xlsReadWrite to read a particular excel file. In one of the
columns I have dates ( say col=5). Now date column is read by default as
numeric. So I used dateTimeAs= "isodatetime". This enables reading in
the date format. However in the earlier column (say col=1) I have dat

This is just
write.graph(g, format="dot", file="output.dot")
in igraph.

Hello Friedrich,
thanks for your help and it is really not important that the solution
is elegant. Important is only that there is a solution.
But I still have some problems with this topic.
#I tried as you suggested to order the vectors separately. My first
problem is that my data is a data
thank you Greg,
this is just what I needed.

Hi,
I have a simulation with negative examples, and with R I can do quite
easily a histogram and a density estimate. I have one positive example
and I want some statistical significance value to see to what extent the
positive example is part of the negative population. Does anyone have an

Sorry, but I can't help you with your problem isntalling ggplot2. I'm a
WinXP user and have no experience with R on Linux. Maybe Hadley Wickam
could help you out on this one.

I think that your approach is reasonable, except that you should use the same
smoothing parameters throughout. i.e the reduced models should use the same
smoothing parameters as the full model. Otherwise you get in trouble if x1
and x2 are correlated, since the smoothing parameters will then ten
