Encoding names used by SAS for the character sets are listed in the fourth column. For example, the Arabic locale in the first column has five compatible character sets: WARABIC, ARABIC, MSDOS720, PCOEM864, OPENED-425. If you started programming in SAS, then the conversion will be hard, but those of us who have changed generally have stuck with R. This table shows languages (locales) that support the same set of characters. The amount of code I need for data manipulation in R is a lot less than the code used by my SAS colleagues. (The comment that data manipulation is "hard in R" just indicates lack of experience. I would argue that its main advantage is superior support for "report writing". At least when I used it 15 years ago, it didn't really have an object model. We can rapidly apply modern advancement such as statistical learning and machine learning in R in comparison to SAS. ![]() You can define functions but it's not the way most people interact with SAS and its data SETs, at least at first. There are more lines of code in SAS than R. I'm being a bit vague in that last sentence, because I lack much experience with them. Reference-classed or R5 or proto-classed objects most resemble true object-oriented programming data types. ![]() The original S3 functions which dispatch only on the class of their first arguments are probably still the most commonly used, although the S4-class which may dispatch on multiple argument signatures is widely used in the BioConductor world. R has between three, four, or five major object classes depending on how you think about them and associated function-types. R uses an object's class as the dispatch selection mechanism for "generic" functions, but that's not the same paradigm as full OO-languages.) (The only reason I'm writing this answer is that calling R an object-oriented language will be misleading to people who come to it expecting to be able to send function messages to data-objects in the same manner as they do with Java. Nonetheless, if you are not willing to adapt your programing style to use functions, you will have quite a bit of difficulty in writing efficient R code. SAS is an integrated software suite for advanced analytics, business intelligence, data management, and predictive analytics. It does have some exceptions where things are done via side-effects, so it's not as entirely functional as Haskell. ![]() R is primarily a functional programming language.
