How to set the number of digits to be printed for summary command without using options(digits) in R?
To set the nuber of digits to be printed for summary command without using options(digits), we can use digits argument while printing the summary. −
Example 1
Using mtcars data and finding the summary statistics with number of digits set to 2 −
summary(mtcars,digits=2)
On executing, the above script generates the below output(this output will vary on your system due to randomization) −
