[R] Prompt comes too late

2007-07-30 Thread Ralf Finne
Hi R fans

I am trying to make a program to ask the user to choose data file:

print(Choose data file please !)

matr=read.table(file.choose(),dec=.,header=TRUE)

The problem is that the prompt 
Choose data file please !   
comes after I have chosen the file.

What  am doing wrong?

Thanks in advance
Ralf Finne

[R] Integrating R-programs into larger systems

2007-04-27 Thread Ralf Finne
Hi experts!

Have anybody experience in including an R-program 
as part of a larger system?  In Matlab there is a toolbox
that converts a m-script into C-code. 
One application in mind is that I do the model building in R,
for estimating the risk for cancer based on clinical measurements.

When the model is ready, a small R-program can simulate
the model to estimate the risk for a new patient. The idea is
that a doctor gets the measurements for the patient sitting in his
office.  Then he goes to Internet and types in the test measuremnets
and gets the estimated risk.
Look at www.finne.info for an early version to get the idea.
There I developed the model in Matlab and converted it to Excel.
Don't use the results!  Much better are available in R!
There are many more applications that need a higher degree
of integration.

Than you in advance.

[R] Neural Network with Multiple Outputs

2006-12-19 Thread Ralf Finne
Hi! I want to use an artificial neural network of
type MLP (Multi Level Perception) as a kind of
generalized regression.  In this case there are several
binary outputs.  I have been using Matlab with
good results.  But has anybody found a good
package in R.
