Re: K-Means Clustering

[Mehmet Hakan Satman]

ok. i will implement the code as you described. 

i think i must download the source from  the adress "git clone git://git.savannah.gnu.org/pspp.git" using git. is this the current up-to-date source?

How can i submit the changes? Before the PSPP, i submit some packages to cran (R project) wia ftp, but this is a complete GNU style.

Thanks.

Hakan.

That's right.  But I would start with something simpler.  Say just
"QUICK CLUSTER x y z".  The syntax parser can be a bit challenging
so keep it simple to start with, and add the options later.

You'll need to write a function of the form:
int cmd_quick_cluster (struct lexer *lexer, struct dataset *ds);
and register it in the file src/language/command.def

I suggest that you look at some of the existing examples to get
an idea of how it works. reliability.c is probably a good example.

   
    also: I have no experience about coding GTK+

The first step will be to get the command written.  You or someone
else can write the GUI for it later.

Good luck.
