Many public, private, and international organizations use R to conduct analysis, thus experience with R is a great skill to add to one's credentials. For example. the National Board of Medical Examiners determines the point–biserial correlation between whether examinees get an item correct (a binary variable) and the examinee's score on the entire exam (a numerical variable). it is the same as for the correlation. Topics covered in the course include sequence alignment, gene finding and annotation, microarray analysis, gene regulatory network, RNA/protein structure prediction, proteomics and pharmacogenetics.
