I Want ggplot2/lattice and d3 (gridSVG–The Glue)

I really like interactive graphics, especially when they come straight from R.  I posted a lot about rCharts, but it is not the only way.  In my mind there are three types of glue to link R to SVG/HTML/Javascript: Let R do the data and then send the data to Javascript to create the SVG graphics....

Introduction I couple of weeks ago I had an idea for a website where people can collaborate to create the first real Audio Atlas, using the power of the Google Maps API. The problem was that I do some programming in R but I did know very few things about HTML and javascript. However, I knew that having...

Visualizing Book Sentiments

Sentiment analysis of social media content has become pretty popular of late, and a few days ago, as I lay in bed, I wondered if we could do the same thing to books - and see how sentiments vary through the story.The answer, of course, was that yes, we could. And if you’d rather just...

Orthogonal Partial Least Squares (OPLS) in R

I often need to analyze and model very wide data (variables >>>samples), and because of this I gravitate to robust yet relatively simple methods. In my opinion partial least squares (PLS) is a particular useful algorithm. Simply put, PLS is an extension of principal components analysis (PCA), a non-supervised  method to maximizing  variance explained in X,

Classification of the Hyper-Spectral and LiDAR Imagery using R (mostly). Part 1: Result Evaluation

Introduction There was the EEEI Data Fusion Contest this spring. This year they wanted people to elaborate about hyper-spectral (142-bands imagery) and LiDAR data. The resolution of the data-set was about 5 m.  There were 2 nominations: best classification and  the best scientific paper.  I work with high-resolution imagery quite often, but classification is a very rear task for me...
