While R is the undisputed champion in academics and research, SAS is extremely popular in commercial analytics. But R and Python are gaining momentum in the enterprise space and companies are also trying to move towards open-source technologies. SPSS is another popular statistical tool.
It is used most commonly in the social sciences and is considered the easiest to learn among enterprise statistical tools. SPSS is loved by non-statisticians because it is similar to excel so those who are already familiar with it will find SPSS very easy to use.

However, even for trivial work, you will need to perform a sequence of steps and it is better to create an R script. You can now see the R Script Editor where you can type and save R programs that span multiple lines. R holds a reputation for getting things done with very little code. In just three lines of code, your first R program will generate 10, numbers in a random distribution, organize them based on frequency and create a fancy barchart. Look at the right bottom section of RStudio and you will see this beautiful bar graph showing the bell curve of a random normal distribution.
The first line generates a list of random numbers in a normal distribution such that the mean of these numbers is and standard deviation Since it is a normal distribution, you can clearly see the frequencies of the numbers gradually increase as we approach the mean. In just one line, we could have done the same thing in one line while adding labels to the x and y axes with. This is the power of the R programming language. As a tool specifically built for statisticians, it performs all common operations using an expressive syntax that you will learn to love.
While RStudio is an amazing tool to get started learning R, it is only an interface to the R console. It is important to be familiar with running R programs directly through the command prompt or terminal because you might not always have access to a graphical interface if you are running R programs on a server. We can start typing commands directly at the prompt and hit return to execute it. As you can see, each command is executed as soon as you press the return key and if there is any output the mean in the above example , then it is displayed. Alternatively, we can execute R commands stored in an external file using the function source as follows.
Sometimes you may need to run an R program inside a batch or shell script.
There are different ways to achieve that. If you want to turn your R program into an executable, you can specify that you want the file to run using Rscript by adding the following line at the beginning of your R script.
