help in SVM
HI, GUYS,
I used the following codes to run SVM and get prediction on new data set hh.
dim(all_h)
[1] 2034 24
dim(hh) # it contains all the variables besides the variables in all_h
data set.
[1] 640 415
require(e1071)
svm.tune<-tune(svm, as.factor(out) ~ ., data=all_h,
ranges=list(gamma=2^(-5:5), cost=2^(-5:5)))# find the best parameters.
bestg<-svm.tune$best.parameters[[1]]

iteration history
Dear R Users
I would like to use optim function to optimize a function. I read help but I
couldn't find what I need: is it possible to get information after each
iteration, for example as there is in MATLAB:
Gradient's
Iteration Func-count f(x) Step-size infinity-norm

nested if/else very slow, more efficient ways?
Hello,
in the data.frame "resultsfuzzy" I would like to replace the
characters in the second column ("5a", "5b", ... "5e") with numbers
from 1 to 5. The data.frame has 39150 entries. I seems to work on
samples that are << nrow(resultsfuzzy) but it takes suspicously long.
Do you have any suggestions how to make the character replacing more

rxfax problem
Hello,
I tryed out spandsp with libtiff-3.5.7 and with Asterisk from CVS.
I tryed to receive a fax on a CAPI channel. Finally I got a file with
8 byte length (/tmp/testfax.tif).
How can I do next?
Thanks in advance,
Thomas
ps: what are hardware requirements for sending/receiving faxes?
