Hi
As I said I have no experience with kernlab but I can read in manual:
"probabilities matrix of class probabilities (one column for each class and one
row for each input)"
from which I understand that pred is matrix, which should have the same number
of rows as df$cons but several columns.
Dear all,
I generated a circular dendrogram with R (see attached). I have a
total of 360 landraces.
What I want to do next is generate a different color for each cluster
and also generate colors to show the country/region.
I don't know if it's also possible to put a code number (associated

Yes, sorry. I attached the file once again.
Well, still getting the same warning.

That said, the gist of the OP's outline is correct, and the main reason to look
elsewhere is to get more thorough advice on what statistical concerns should be
addressed than would be on topic here.

Your attached file is not a .csv file since the field are not separated by
commas (just rename the mydata.csv to mydata.txt).
The command "genod2 <- as.matrix(genod)" created a character matrix from the

becomes NAs wh

Guys,
lattice is a "recommended" package, which means that it is installed by default
with any standard R installation.
Thus, all that is required, as Sarah noted in an earlier reply, is either:
library(lattice)
or
require(lattice)
depending upon preference.

Dear All,
I am trying to build a model by doing recursive elimination of weights one
by one.
This is the example matrix

weights 0.000236 0.004591 0.00017 0.018113 0.000238 0.006537 N/A

This list is (mostly) about R programming. Your query is (mostly) about
statistics. So you should post on a statistics site like
stats.stackexchange.com
not here; I am pretty sure you'll receive lots of answers there.
Cheers,

Hi R-list,
We have constructed a hurdle model some time ago.
Now we were able to gather new data in the same city (38 new sites), and
want to do an external validation to see if the model still performs ok.
All the books and lectures I have read say its the best validation option

Dear Meriam
Your csv file did not come through as attachments are stripped unless of
certain types and you post is very hard to read since you are posting in
HTML. Try renaming the file to .txt and set your mailer to send
plain text then people may be able to help you better.

please post a sample dataset based on
mydata <- rbind[participant1[1:3,], participant2[1:4,], participant3[1:5,])
I think mydata at this point is anonymized enough that you can post
it. Verify with whomever, though.
You might want to change those random U* names of the participants to

Hi,
the maintainer hasn't answered yet. The problem with 'acc' is that yes
the objects are not of the same length but they should be: according
to the manual, ' table(pred, df$cons)' would return a 2x2 matrix of
the results. This is not the case, so there is a problem with the
model -- that is why

xyplot is not a package, it is a function within the lattice package, which
should already be installed.
library(lattice) # load the package from the R library
?xyplot # look at the help for the function
The others are also functions, not packages.

Dear Nick,
The best solution is not to use which() but directy use the logical test.
This will work in case the condition is always FALSE and which() returns a
integer(0). And it is much faster too.
z <- y > 3
y[!z]
library(microbenchmark)
microbenchmark(
y[!y > 3],
y[-which(y > 3)]
)

In the work I'm doing I often have this situation and have to make sure that I
condition on z being non-zero as y is now numeric(0) rather than the set
c(1,2,3). Why does R do this? Wouldn't it be more sensible for R to simply
leave the host set unchange
