I’ve been wondering if this year’s useR conference foreshadowed some gigantic groundbreaking change in the world of R. The previous useR conference was a sort of catalyst for dplyr package and operator %>%. The profession (especially from California)…
deepsense.io and Hortonworks, a leader in the Enterprise Hadoop Solutions Industry, agreed on establishing a technology partnership and plan to expand it this year.
Recently I tested a quite nice package for R: wikipediatrend (available on CRAN). With just a few lines of code, it can easily download and visualize daily wikipedia page views statistics. Great package, so we are going to take a closer look. I’ve just finished Season…
Archivist is an R package for object management (storing, sharing, searching). I am going to present it on useR conference next week (hope I can meet some of you in Aalborg). Below you will find two coolest (imho) features implemented in the version 1.5 of archivist.

deepsense.io has just revealed who will support it within the Scientific Advisory Board. The think tank is created of people related to data analysis, working on various scientific and commercial projects all over the world. Among the members there are names with particularly huge academic output, like Jan Madey and Krzysztof Diks, as well as their students, finalists of informatics olympiads.
deepsense.io is a startup supported by CodiLime, a growing Polish software company. The main project being developed by the best programmers Poland has to offer is DS Studio, an innovative platform for complex Big Data analysis using machine learning solutions. This is precisely what will be presented at two large IT conferences taking place in June in California: Hadoop Summit and Spark Summit.
I’m forming a group of students and grads interested in data analysis: The MI^2 (square) Group. The name comes from the fact that we have students from MIM University of Warsaw and MINI Warsaw Technical University. We are playing with different projects and ideas…
I’ve recently worked on an interesting problem. There are two types of mice. We select three animals of each type. We want to examine an effect of given treatment on nerve cells, more specific: on their dendritic spines (small protrusions located at neurons). From…
