R and package masking - a real life example

Posted by on Apr 15, 2015 in R blog | 1 comment

From original post @http://analyticsblog.mecglobal.it/en/analytics-tools/masked-r-packages/ Very often, in our coding life, we forget one very simple yet important point to take care to: the importance of conflicts between packages. When you load a library in best case the command line is executed with no problem. However, the console is sometimes stuffed with red messages that we often ignore, moreover when the function we need reach the desired goal. Sooner or later during your R-user life you could stack in an error, and you could get...

R Machine Learning Essentials

Posted by on Feb 18, 2015 in R blog | 0 comments

This week, the post is an interview with Michele Usuelli. Michele is the author of the book "R Machine Learning Essentials". Hi, Michele. Welcome back to MilanoR. You're the second author of this blog, after Max Marchi, who wrote a book about R. How has this idea started? Everything started when Pack Publishing contacted me on LinkedIn out of the blue. First, they proposed me to write a book about a well-know R tool to build charts: the ggplot2 package. Since I was more interested in writing about Machine Learning techniques rather than an R...

Bash+R: howto pass parameters from bash script to R

Posted by on Feb 11, 2015 in R blog | 2 comments

From original post @ http://analyticsblog.mecglobal.it/analytics-tools/bashr/ In the world of data analysis, the term automation runs hand in hand with the term “scripting”. There’s not the best programming language, only the most suitable to perform the required function. In our case, many data aggregation procedures are run from unix/linux servers, collecting API data in real time, so it becomes essential to make sure that data is formatted and correctly stored for the analysis/visualization needs. In our case some automatic procedures run...

Building a choropleth map of Italy using mapIT

Posted by on Jan 20, 2015 in R blog | 5 comments

In the R environment, different packages to draw maps are available. I lost the count by now; surely, sp and ggmap deserve consideration. Despite the great availability of R functions dedicated to this topic, in the past, when I needed to draw a very basic map of Italy with regions marked with different colours (namely a choropleth map), I had a bit of difficulties. My expectation was that building a choropleth map of Italy using R was a extremely trivial procedure, but my experience was different. In fact, if the aim is to represent a map of...

The R user point-of-view about "Statistics Without the Agonizing Pain"

Posted by on Jan 13, 2015 in R blog | 0 comments

Contrary to general expectations, or at least to my expectations, the logical and analytical concepts behind statistics are rather difficult to understand by engineers. In general, despite their heavy background in maths and their above average fluency with computer programming, there seems to be a broken bridge with the statistical world and often they prefer to stay in the safe "math bank" of the river, despite the road to statistical fluency is shorter than they think. For example, I noticed the aforementioned issue as I heard engineers...
