Project Ajna


Dear readers,

The first version of the project Ajna was released ! ! ! !

Ajna is a web tool based on R Shiny and Bootstrap, intended to help in the process of Exploratory Data Analysis.

So far there is no target audience (business users, data analysts, etc.). It was created in the spare time during the last 2 days to explore R Shiny with Bootstrap. I think I will define the target on-the-fly. I just wanted to take it from the idea stage, implement and share as a skeleton, so people can build upon.

To access the web tool, use the following link:

To test the tool, I suggest to download and use this file: wine.csv

I am still working on the functionalities, but I hope soon release the newest version and also publish the code in my GitHub account.

Version 1 – Functionalities:

1 – Load data and order data by column

2 – Univariate analysis (descriptive statistics and histogram)

3 – Bivariate analysis (Scatter Plot, Basic Time Series Plot with Loess Smooth, Line Interpolation Options Plot and Pair Correlation Plot)

4 – Multivariate analysis (Correlation Plot)

Any feedback is very important. If you used the tool and want to suggest a functionality, please, leave a message in the contact form.


Learning, Unlearning and Relearning

Some years ago I stumbled in a little sentence that I can say “it really changed the way I live and see things”.

The sentence was:

The illiterate of the 21st century,” Alvin Toffler famously said, “will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.

My thought is that you don’t need to learn the whole world in a day, month or year.

You just need to learn one thing per day and it will force you to learn new things, and amazingly unlearn and relearn what you already know, but by a new perspective.

Sounds curious? If so, just try it right now!

If you understand by heart what it means, please share your thoughts in the comments.

Since then I have been paying more attention to learning habits and today I just stumbled in a really good list of “Interesting Articles Study Skills and Habits”.

It would be a pleasure to share with you …  so let’s go! ->
