Principal component analysis (PCA) is very useful for doing some basic quality control (e.g. looking for batch effects) and assessment of how the data is distributed (e.g. finding outliers). A straightforward way is to make your own wrapper function for prcomp and ggplot2, another way is to use the one that comes with M3C (https://bioconductor.org/packages/devel/bioc/html/M3C.html) or another package. M3C is a consensus clustering tool that makes some major modifications to the Monti et al. (2003) algorithm so that it behaves better, it also provides functions for data visualisation. Let’s have a go on an example cancer ... Read More

If you spend any time working with maps and spatial data, having a fundamental understanding of coordinate systems and map projections becomes necessary.  It’s the foundation of how spatial data and maps work.  These areas invariably evoke trepidation and some angst, even in the most seasoned map professional.  And rightfully so, it can get complicated quickly. Fortunately, most of those worries can be set aside when creating maps with SAS Visual Analytics, without requiring a degree in Geodesy. Visual Analytics includes several different coordinate system definitions configured out-of-the-box.  Like the Predefined geography types (see ... Read More
