saving a regression model to a file
Hello all,
First off, I am using R version 2.13.0 in Ubuntu.
I have read previous posts in the R mailing list on saving models for
later use, and the responses indicate using the R save() function to
save a model and then using load() to load it is one way to go.
However, when I use the save() function to save a model to a file, and
then try to load it using load(), the loaded "model"

Activation Functions in Package Neural
Hi,
I am trying to build a VERY basic neural network as a practice before
hopefully increasing my scope. To do so, I have been using package "neural"
and the MLP related functions (mlp and mlptrain) within that package.
So far, I have created a basic network, but I have been unable to change the
default activation function. If someone has a suggestion, please advise.

Getting the C-index for a dataset that was not used to generate the logistic model
Does anyone know how to get the C-index from a logistic model - not using
the dataset that was used to train the model, but instead using a fresh
dataset on the same model?
I have a dataset of 400 points that I've split into two halves, one for
training the logistic model, and the other for evaluating it. The structure
is as follows:
column headers are "got a loan" (dichotomous),

Help in using PCR
Hi,
Currently I have a dataset of 2400*408. And I would like to apply PCR method
to study the any correlation between the tests.
My current data is in data.frame and I have formed horizontal(1-407) to be
the exact data, and (408) to be my results data(Yes and No)
I have also binarized these Yes and No to 1 and -1s.
However, when I refer to PCR manual on R, the example of yarn.pcr <-

logistic regression
Hi everyone,
I'm sorry if this turns out to be more a statistical question than one
specifically about R - but would greatly appreciate your advice anyway.
I've been using a logistic regression model to look at the relationship
between a binary outcome (say, the odds of picking n white balls from a bag
containing m balls in total) and a variety of other binary parameters:

problems with extractPrediction in package caret
Hi list,
I´m working on a predictive modeling task using the caret package.
I found the best model parameters using the train() and trainControl() command. Now I want to evaluate my model and make predictions on a test dataset. I tried to follow the instructions in the manual and the vignettes but unfortunately I´m getting an error message I can`t figure out.

Stacked bar plot of frequency vs time
Hi All,
New to R, but committed. I looked in a number of places but can't figure out
my current problem. I have date of the type:
Time Type1 Type2 Type3
1 .50 .25 .25
4 .55 .25 .20
5 .65 .20 .15
etc
which describe the frequency of types 1, 2 and 3 (adding up to 100%) over
time. I would like to create a stacked bar chart showing these

[LLVMdev] bitconvert for multi-typed RegisterClasses

I'm working on a back end for an architecture that makes use of multi-
typed register classes.

When running some preliminary tests I found that the instruction
selector refused to select certain ops (specifically stores) for some
instructions when the operand type wasn't the first type for the

eliminating constant variables
Hi all,
I have a large data set and want to immediately build a 'blind' model
without first examining the data. Now it appears in the data there are a lot
of fields that are constant or all missing values - which prevents the model
from being built.
Can someone point me the right direction as to how I can automatically purge
my data file of these useless fields.
Thanks in advance,

Ggplot: free x-scales in a facet-grid
Hello,
I have a ggplot that has the looks of the plot that I want, but it doesn't
have the right layout.
The data is an ordered melted dataframe:
- ID
- type (to use for a faced grid)
- time - type
- time - value (POSIXct)
- pos (to use for a faced grid, this is an index to split the plot)
The goal of the plot is to create a time line for each ID (different points
of time). The ID's

about data export
Hello all,
This is Meghana.
Well, I have some analysis output in 3 dimensional array form.
for example:
, , type1
A B C D
1 2 3 4
1 2 3 4
, , type2
etc.
This array is very big. and I want to export this to either text form or
excel(csv is preffered) so that different parts of aaray should be easily
extractable from that excel/text sheet.
How can I go about it?
Thank

different data series on one graph
Hello,
I'm looking for a way to plot different data series on one graph.
I have a series of hourly rainfall and quarterly flow
measurements (i.e. 4 times an hour) of a catchment. The rainfall
should be plotted in bars, the flow as a line. Both on the same X
axe (time) but with different Y axes.
The problem is the plot() function does not support add=TRUE...
Furthermore I'm not sure
