Efficient programming is a crucial skill for producing the right outcome, on time. But coding is just one part of a broader skillset necessary for thriving results for projects involving R programming. Until your project is to write down generic R code (i.e. unless you happen to be around the R Core Team), the project will most likely transcend the confines with the R world: it will have to interact with a whole range of other variables.
R language was proven from S language being an execution system with a mix of lexical scoping semantics. R language provides a broad scope visual and analytical techniques like linear and non-linear modeling, classical and analytical assessments, time-series Assessment and class clustering.
