language is widely used for virtually any application, discipline, or field of study because of its graphical capabilities as well as GIS capabilities, not to mention the ability to provide extra functionalities through its dedicated packages.  

To help you better understand the concept of R language, listed below are its features and advantages.

  2. Repeatable or reproducible function – by just copying and pasting R code, it allows you to recreate your problem  
  3. Scalable – applicable to small and large systems 
  4. Highly compatible – can be integrated with various database management systems, technologies, and even other programming languages like Python, Java, etc.

Things to Remember When Using R for the First Time 

  • R is case sensitive – make sure words are spelled correctly 
  • R is command-line driven – it won’t run if command prompts are incomplete 
  • Use the # symbol before any text (e.g. #instructions, #notes, #comments) that you want R to ignore 

R has a steep learning curve but with enough self-motivation and lots of practice, you should be good to go after some hands-on training. If you want to learn R from scratch, ClinkIT Solutions PH offers free resources to make you R expert.
