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
