R - range() Function

The R range() function returns a vector containing the minimum and maximum of all the given arguments. The syntax for using this function is given below:

Syntax

range(..., na.rm = FALSE, finite = FALSE)

Parameters

`...`	`Required.` Specify any numeric or character objects.
`na.rm`	`Optional.` Specify TRUE to remove NA or NaN values before the computation. Default is FALSE.
`finite`	`Optional.` Specify TRUE to remove Inf, -Inf, NA or NaN values before the computation. Default is FALSE.

Return Value

Returns a vector containing the minimum and maximum of all the given arguments.

Example:

The example below shows the usage of range() function.

v <- c(10, 15, 20, 25, 30, 35, NA, NaN, Inf, -Inf)
cat("The vector contains:\n")
cat(v, "\n\n");

cat("range(v): ", range(v), "\n")
cat("range(v, na.rm=TRUE): ", range(v, na.rm=TRUE), "\n")
cat("range(v, finite=TRUE): ", range(v, finite=TRUE), "\n")

The output of the above code will be:

The vector contains:
10 15 20 25 30 35 NA NaN Inf -Inf 

range(v):  NA NA 
range(v, na.rm=TRUE):  -Inf Inf 
range(v, finite=TRUE):  10 35

Example:

Consider one more example where the range() function is used with matrix.

m <- matrix(c(10, 50, -10, 100, NA, NaN, Inf, -Inf), nrow=2)
cat("The matrix contains:\n")
print(m);

cat("\n");
cat("range(m): ", range(m), "\n")
cat("range(m, na.rm=TRUE): ", range(m, na.rm=TRUE), "\n")
cat("range(m, finite=TRUE): ", range(m, finite=TRUE), "\n")

The output of the above code will be:

The matrix contains:
     [,1] [,2] [,3] [,4]
[1,]   10  -10   NA  Inf
[2,]   50  100  NaN -Inf

range(m):  NA NA 
range(m, na.rm=TRUE):  -Inf Inf 
range(m, finite=TRUE):  -10 100
