Hi Henrik, 2016-03-08 16:57 GMT-03:00 Henrik Nergaard <henrik.nergaard(a)uia.no>: > #withAllSubclasses > > TextMorphForFieldView withAllSuperclasses reversed collect: [ :cls | cls -> {cls instVarNames . cls methods }]. I was doing something similar like: MyClass withAllSuperclasses reversed flatCollect: [ :cls | cls instVarNames ]. But I was asking if there was a tool that already provides that. Thank you!

AsciiDoc is an exporter like Pillar, you can export you asciidoc file to pdf or something else. For the moment, this format allows generate files in format that Pillar can't know. I hope I answer your question

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

by Werner Kassens

Hi Vincent, it would perhaps be helpful if you could specify your proposal "Standard statistical tests: normality, variance, mean, distribution" a bit, because eventually some of these are already implemented and would just need a wrapper to be easily usable. perhaps it would be enough if one would know which R-functions you use or so, and what kind of return you'd expect. werner On 03/03/2016 10:43 AM, Blondeau Vincent wrote: > Hi, > > That's a very good idea. > For now, I use a Pharo-R binding to make the statistics, but it is better if it is directly in the image. > > For my part, it should be nice to have: > - Principal Component Analysis > - Time series > - Correlation with several variables (Correlation matrix) + significance tests (pearson, spearman...) > - Standard statistical tests: normality, variance, mean, distribution > - And the more important is to have nice tools to visualize the data (Box plot, histogram, scatterplots, PCA ones) with a simple API for standard things but that we can customize.
