The main idea of this post is to answer what high dimensional data is, its main challenges at the moment to create a visualization and offer examples about the adequate plots for this kind of data. If you master this area and you want to explore some papers, you can check some of them in…
Big data is evolving incredibly fast during the last years, and most of the companies are trying to implement data science projects with different complexity and variable results. . In this post I would like to explore some papers and articles about what companies want from data science projects, what are the main benefits from…
Managing the organization of a data project means evaluate what are the objetives of your organization system, how do you want to structure your data, the way that you want to have a backup system and a version control and finally how to document all your processes.
“To achieve great things, you need a plan and not quite enough time”.

Steps on a data cleansing for real-world datasets. The foundational base before to start with the process of exploratory analysis is obtain a tidy dataset, full of reliable data.
Heatmaps visualise data through variations in colouring. There are different functions to create a heatmap, one of them is using the heatmap function, but it is also possible to create a heatmap using geom_tile from ggplot2. The election for one of these function relies on the dataset. Below there is an example developed step by…
A heatmap is basically a table that has colors in place of numbers. Colors correspond to the level of the measurement. Each column can be a different metric like above. It’s useful for finding highs and lows and sometimes, patterns. From Nathan Yau | Visualize This One of the problems when we have a…
One of the most important things about graphs is the election of the colors. Color could change the mood of the image, or impact the story, also guide the viewer thought the elements into the visualization. The election of colors is notably important. The physics, technology, and neuroscience behind the interpretation of colors is surprisingly…
In this article, I explore what the User Conference is, the cities where the conferences took place during the last years, and also I explore the next town where the user conference 2019 will happen: Toulouse. All the maps for each of these places are created using the ggmap package and the raster package A…
