Re: [JPP-Devel] Methods to calculate Frequency in OJ?

2018-05-21 Thread Stefan Steiniger 

Hi Peppe,

not that I know of... I was thinking there could be something related to 
colors theming - but I don't think so with respect to the type you want 
i even doubt that jmath has. I used only "counts" (like for histograms); 
which is a bit different - or? But you could also check if Sextante has 
something?


For OJ source code you could just run a text search using "frequency"

cheers,

Stefan

Hi Peppe,

I think that OpenJUMP plugins including statistical functions make use 
of jmatharray-20070905. It does not include so many functions, but it 
is very lightweight.

Maybe Stefan knows a bit more about it.

Maybe there are some other places where statistical functions have 
been coded. Do cou need it for feature attribute analysis or for image 
analysis ?

Hi all,
do we have calsses/methods in OJ core to calculate frequencies 
(absolute, relative and cumulative) of an array of numbers? I can 
implement these methods but I would prefer to use something already 
in the OJ source.

thanks
Peppe
