rscript: Execute one or more R expressions.
$ Rscript -e ${expression1} -e ${expression2}
try on your machine
This command is used to execute R (programming language) code from the command line. Here is the breakdown of this command:
Rscript
: This is the command-line executable for running R scripts.-e
: This flag specifies that an expression should be executed.${expression1}
and${expression2}
: These are variables representing R expressions that will be executed.
In other words, when you run this command, Rscript will execute the two provided expressions (${expression1}
and ${expression2}
) sequentially. These expressions can be any valid R code, including calculations, data manipulation, function calls, etc.
For example, if you have the following R expressions:
- Expression 1:
print("Hello, world!")
- Expression 2:
x <- 2 + 3
The command Rscript -e 'print("Hello, world!")' -e 'x <- 2 + 3'
will execute these expressions one after the other. The output will be the printed message "Hello, world!" and the variable x
will be assigned the value 5 in the R environment.
