daru project

[Deepak Koli]

Hi,

I'm interested in the "Improving the capabilities of daru" project. Can someone please help me in getting started with the project.

Thanks

See the daru repo at www.github.com/v0dro/daru. Check the issue trackers and README to get started.

For improving the capabilities of daru it is recommended that you are familiar with data analysis suites like pandas in Python or data.frame in R. The project mainly involves making daru as useful as pandas or data.frame for data analysists and regular Rubyists.

You can suggest your own ideas for improvements in daru, wherever you deem necessary.

Hi,

I've set up the development environment for daru gem. I'm currently going through the code of daru and familiarising myself with pandas. Should i look into how to extract data from various internet sources into a DataFrame like pandas does?

Hey Sameer, 

Can you take a look at this basic prototype for stock data reader from yahoo finance

Thanks

[Sameer Deshmukh]

Looks good!

You should support precision upto minutes in case of stock data.

[Deepak Koli]

Can you give me an ideas as to what all features should be supported under time series sampling?

[Sameer Deshmukh]

You can start by porting pandas functions to daru.

[Deepak Koli]

We can create a method whose parameters will be: a series, number of samples, method of sampling (like sum or mean), an optional fill method. 

Choice of fill methods can include: forward fill, backward fill, interpolation.

[Deepak Koli]

Can i start porting after submitting the proposal?

Or do i need to do it before to have shot at getting selected? :P

[Sameer Deshmukh]

You need to figure out the most important methods and give us reasons as to why they should be ported to daru in your proposal. Also include the implementation details and code samples wherever necessary.

Coding happens later.

Saurabh Shah is also working on this idea. You might want to co-ordinate with him.
