6. Browser based Ruby REPL for interactive computing. @srijan #SrijanWW
7. Runs in your browser Input cell – accepts Ruby code Output cell – can render HTML/CSS/JS @srijan #SrijanWW
8. @srijan #SrijanWW
9. nmatrix @srijan #SrijanWW
10. n­dimensional array object. Interface Ruby with high speed C libraries. @srijan #SrijanWW
11. require 'nmatrix' n = NMatrix.new( [2,2], [1,2,3,4], dtype: :float32, stype: :dense ) n[0,1] # => 2.0 @srijan #SrijanWW
12. Data Types :int8 :float32 :int16 :float64 :int32 :complex64 :int64 :complex128 @srijan #SrijanWW
13. Storage types Dense Dense matrix. List Sparse matrix type storing data as a linked list. Yale Sparse type storing data in the 'New Yale' format. @srijan #SrijanWW
14. NMatrix C API @srijan #SrijanWW
15. nmatrix nmatrix­ atlas nmatrix­ lapacke nmatrix­ fftw gsl @srijan #SrijanWW
16. nmatrix is coming to jruby! @srijan #SrijanWW
17. nyaplot @srijan #SrijanWW
18. interactive plotting tool for Rubyists. @srijan #SrijanWW
19. interactive HTML and JavaScript plots that can be displayed in your browser. @srijan #SrijanWW
20. @srijan #SrijanWW
21. Mapnya Nyaplot3D Bionya Map visualizations with inbuilt country charts. Three Dimensional interactive plots. Biology plots for visualizing relationships of genes. @srijan #SrijanWW
22. gnuplotrb @srijan #SrijanWW
23. Ruby wrapper over GNU Plot. Convieniently exposes all GNU Plot functions through Ruby. @srijan #SrijanWW
24. require 'gnuplotrb' plot = GnuplotRB::Plot.new( [ [1,2.5,1.5,4], with: 'linespoints' ] ) @srijan #SrijanWW
25. @srijan #SrijanWW
26. require 'gnuplotrb' plot = GnuplotRB::Plot.new( [ [1,2.5,1.5,4], with: 'linespoints' ], [ [2,3,4.3,3], with: 'lines' ] ) @srijan #SrijanWW
27. @srijan #SrijanWW
28. statsample @srijan #SrijanWW
29. @srijan #SrijanWW library for statistical analysis and modelling.
30. @srijan #SrijanWW Extensions for Generalized Linear Models and TimeSeries apart from statistical tests and models.
31. daru (Data Analysis in RUby) @srijan #SrijanWW
32. daru == (Hindi) ददार @srijan #SrijanWW
33. library for analysis, cleaning, manipulation and visualization of data. @srijan #SrijanWW
34. Read/write many data sources Ephemeral statistics functions Works well with 'wild' data Data indexing @srijan #SrijanWW
35. Acts as glue between other SciRuby libraries. @srijan #SrijanWW
36. Daru::Vector Heterogenous Array that can be indexed on any Ruby object. Name Label(0) Label(1) Label(2) ... Label(n-1) @srijan #SrijanWW
37. Daru::DataFrame 2D spreadsheet like data structure indexed by rows or columns. Col0 Label(0) Label(1) Label(2) ... Label(n-1) Col1 Col2 Col(n-1) .... @srijan #SrijanWW
