Re: [Pharo-users] GTSpotter fuzzy search

Hi, Would you like to try to propose a implementation for this? This would fit as a subclass of GTFilter?

Re: [Pharo-users] [Pharo-dev] Call about Numerical Methods in Pharo :)

Hi Alex, This binding allows to execute (almost) any function provided by R via Native Calls. You can find some documentation here: http://smalltalkhub.com/#!/~VincentBlondeau/RProjectConnector I just released a new stable version, you should be able to load it from the catalog (Pharo40 only). However, you must install R and copy the libraries in the VM folder (see doc). And it is working only with pre-spur images (the migration to FFI has to be done). Try to run the tests (in RConnector package). Iff they are green, you succeeded to configure the binding. And you can plot the famous Iris Data: iris := 'eval' asREval: { RObject findVar: 'iris' }. 'plot' asREval: {(iris at: 'Petal.Length'). (iris at: 'Petal.Width'). (#pch -> 21). (#xlab -> 'length'). (#ylab -> 'Width'). (#bg ->((iris at: 'Species') collect: [ :value | {'red'. 'green3'. 'blue'} at: value ])). (#main -> 'Edgar Anderson''s Iris Data')}. plot(iris$Petal.Length, iris$Petal.Width, pch=21, bg=c("red","green3","blue")[unclass(iris$Species)], main="Edgar Anderson's Iris Data") is the genuine R function. And inspect them: iris inspect You can use any collection of pharo and put it as argument, it should do the boxing automatically. Warning: while testing new functions, donât forget to save because evaluation of a non-existing R function throws a error that is not caught and makes Pharo crashing.

We would like to do several things: - Work on "Hows to" The numerical methods in Pharo is good but the gap between us and the math is too large :) so the idea is to have a series of "how to ..." - histomgram (simple, based on distribution) - Improve the SciPharo/NumPha (previously SciSmalltalk) library This morning we started to implement a ComponentPrincipalDecomposition by combining two of the objects available in SciPharo.

Re: [Pharo-users] Voyage, Magritte descriptions, and nil exceptions

by Norbert Hartl

Sabine, maybe my description wasn't clear enough. If you start to use voyage like that you have the constraint that all objects returned from the collection need to be the same or a subclass of the one you are using to search. Meaning If you query One selectAll then all of the objects in the Numbers collection need to be the same class or a subclass of One. So this use case is at first only feasible if you want to find all instances of Numbers. Your basic query needs to be Numbers selectAll If you then want to deal only with instances of One you would need to add this to the query Numbers selectMany: { '#instanceOf' -> #One } asDictionary This is not a nice approach but for this use case it should give you the desire result.
