R help - Jul 2011 - Writing the output of a regression object to a file

Hi,

I'm using R 2.12.0 on Windows XP.

I've used the e1071 package to tune a Support Vector Regression object
and I've created the SVR object:
> epsilon.svr <- svm(C8R004 ~.,data = rain_flow.train, scale = T, type =
"eps-regression",
+ kernel = "radial", cost = 0.9, epsilon=0.55,tolerance=0.001,
shrinking=T, gamma=0.18,fitted=T)
> esvr.pred <- predict(epsilon.svr,newdata = rain_flow.test)
I would like to export the esvr.pred object to a file so that I can
draw a graph of it against my original data in other software that I'm
using.

I've tried the write.svm command, but that outputs the scaled data
instead of something that I can directly compare to my original data.

Does anyone know of an easy way to get the result such a format?

Alternatively, how can I use the scale values to generate such a format?

Thanks
Hanlie

you cannot do this. You can export **data**, but of course any R
"object" is either a binary or text (via dput) representation of an R
structure, which can only be understood by R, not another software
system.

See ?write, ?write.table, or the R import/export manual for how to
export data (as text) to be imported by other software.


Cheers,
