plotting in R
Hello,
As a result of running linear discriminant analysis, I need to be able to
plot the resulting file. I am not sure what the best way to do this is. So
far I have tried regular plot("insert_file_name_here") command but the error
it gives me is Error in plot.new() : figure margins too large
here is sample LDA code I am working with ....

Changing MaxNWts with the mi() function (error message)
Hello,
I am trying to impute data with the mi() function (mi package) and
keep receiving an error message. When imputing the variable, "sex,"
the mi() function accesses the mi.categorical() function, which then
accesses the nnet() function. I then receive the following error
message (preceded by my code below):
> imputed.england=mi(england.pre.imputed, n.iter=6, add.noise=FALSE)

Differing Variable Length Inconsistencies in Random Effects/Regression Models
Dear All,
I am quite new to R and am having a problem trying to run a linear model
with random effects/ a regression- with particular regard to my variable
lengths being different and the models refusing to compute any further.
The codes I have been using are as follows:
vc<-read.table("P:\\R\\Testvcomp10.txt",header=T)

Changing model parameters in the mi package
I am trying to use the mi package to impute data, but am running into
problems with the functions it calls.
For instance, I am trying to impute a categorical variable called
"min.func." The mi() function calls the mi.categorical() function to
deal with this variable, which in turn calls the nnet.default()
function, and passes it a fixed parameter MaxNWts=1500. However, as

Ayuda con Mice con polyreg
Saludo gente, antes que nada gracias por la ayuda que puedan aportarme, soy
iniciante en R, estoy usando el paquete Mice para realizar imputaciones
múltiples sobre variables en su mayoría categóricas. El problema está que

Adjusting MaxNwts in MICE Package
Hi,
I'm trying to impute a large data set using mice but I keep getting this:
Error in nnet.default(X, Y, w, mask = mask, size = 0, skip = TRUE, softmax =
TRUE, :
too many (2944) weights
nnet.default uses the argument MaxNWts to set a maximum number of weights.
I've tried to change nnet.default to get around this, but mice is somehow
still passing an argument that sets the maximum

difference of the multinomial logistic regression results between multinom() function in R and SPSS
Dear all,
I have found some difference of the results between multinom() function in
R and multinomial logistic regression in SPSS software.
The input data, model and parameters are below:
choles <- c(94, 158, 133, 164, 162, 182, 140, 157, 146, 182);
sbp <- c(105, 121, 128, 149, 132, 103, 97, 128, 114, 129);

Neural Network Question
Hi,
I'm using the R nnet package to train a classifier to recognise items which belong to a particular class and those which don't belong to the class.
I'm supplying nnet with a matrix x containing training examples (in each row) and a matrix y of targets. The training set is made up of 200 positive examples and 1000 negative examples. I want to train the network on the same

problem with nnet
Hello All,
I am working with samr and nnet packages.
I am following the steps given below:
1> I take a input file with signal values for 9506 genes and 36 chips
, belonging to two classes.
2> I perform samr analysis on 80% of chip data from both the
classes.(selected by random sampling)
3> I then use the data of only the significant genes from this samr
analysis to train nnet.

front- end problem while using nnet and tune.nnet
Dear R people,
I am using tune.nnet from e1071 package to tune the parameters for nnet.
I am using the following syntax:
tuneclass <-c(rep(1,46),rep(2,15))
tunennet
<-tune.nnet(x=traindata,y=tuneclass,size=c(50,75,100),decay=c(0,0.005,0.010),MaxNWts
= 20000)
Here traindata is the training data that I want to tune for nnet which
is a matrix with 61 rows(samples) and 200

caret() train based on cross validation - split dataset to keep sites together?
Hello all,
I have searched and have not yet identified a solution so now I am sending
this message. In short, I need to split my data into training, validation,
and testing subsets that keep all observations from the same sites together
? preferably as part of a cross validation procedure. Now for the longer
version. And I must confess that although my R skills are improving, they
are not so

Grid drawing over the filled.contour's legend
Hello,
For a reason I can't seem to figure out (have searched posts on this forum
for "filled.contour grid"), the grid (in the code below) is plotting over
the legend that accompanies the filled.contour. The dataset has 40 columns
and 20 rows. Where have I gone wrong? How can I draw a grid with 40
columns and 20 rows that is constrained to the plotted region and doesn't

Tooltip.js problems
I''m starting to play with the tooltip.js library from
http://tooltip.crtx.org/index.php?page=HomePage. The libarary seems to
work pretty well except that when I use a tooltip on a web page that has a
form and submit buttons, the submit buttons stop functioning and won''t
respond to click events anylonger. So far I''ve only been able to
reproduce this under Safari.

LDAP Authentication fails with ñ character in password.
Hi Guys,
I''ve got a rails application that uses activeldap to authenticate
users. Its been working great for about 6 months now, but a user from
mexico started using it recently, but can''t seem to login. I''ve
narrowed it down to the fact that his password contains a ñ character
in it. This problem is also present in a test user account I''ve setup.

R-2.2.1-INSTALL Issue with TCLTK
Hi
I am not able to have a working tcltk library in R-2.2.1 inspite of
trying different options suggested in the FAQ's. I am using the

with a missing libs folder.
