Hi, Sorry that I have many questions today. I am using svm function on about 180,000 points of training set. It takes very long time to run. However, I would like it to spit out something to make sure that the run is not dead in between. Would you please suggest anyway to do so? And is there anyway to speed up the performance of this svm function? Thank you. - adschai
adschai : this isn't particularly helpful but when I am using a function from a package called xxx that I have little knowledge about, I take the source as is and create my own function out of It called my.xxx and then put print statements Inside it to see what's going on. This is probably an extremely kludgy way of dealing with that problem But it is a way. I'm not R expert enough to know any other way but I would Be interested if you get a better private reply. -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of adschai at optonline.net Sent: Thursday, July 05, 2007 12:36 AM To: r-help at stat.math.ethz.ch Subject: [R] Question for svm function in e1071 Hi, Sorry that I have many questions today.

Adschai: The function is written in C++, so debugging the source code of the R svm() function will not really help. What you can do to make the C-code more verbose is the following: - get the sources of e1071 - in the src/ directory, look up the svm.cpp file - In line 37, there is: #if 0 void info(char *fmt,...) [...] replace the first line by: #if 1 - build and install the package again. Best David ---------------------------- Sorry that I have many questions today.
