Get the Minimum and Maximum element of a Vector - range() Function in R

The range() function in R provides a way to simultaneously get the minimum and maximum values from a numeric object, primarily from vectors. It's a convenient function when you want a quick look at the spread or range of your data.

In this tutorial, we'll delve into the usage of the range() function with vectors in R.

1. Basic Usage with Vectors

The range() function will return a vector with two elements: the minimum and the maximum.

vec <- c(5, 3, 9, 2, 7)

# Get the range
vec_range <- range(vec)
print(vec_range)  # Outputs: 2 9

2. Using `range()` with Missing Values (NA)

By default, if your vector contains missing values (NA), the range() function will return NA. To omit the missing values and get the range of the available numbers, use the na.rm argument.

vec_with_na <- c(5, 3, NA, 9, 2, 7)

# Get the range ignoring NA
vec_range <- range(vec_with_na, na.rm = TRUE)
print(vec_range)  # Outputs: 2 9

3. Using `range()` with Matrices

When applied to matrices, the range() function will consider all the elements and return the minimum and maximum values.

mat <- matrix(c(1, 2, 3, 4, 5, 6), ncol = 2)

# Get the range
mat_range <- range(mat)
print(mat_range)  # Outputs: 1 6

4. Using `range()` with Data Frames

With data frames, range() will consider all columns and give the overall minimum and maximum values. If you're interested in the range of a specific column, you can reference it.

df <- data.frame(A = c(1, 3, 5), B = c(4, 2, 6))

# Get the range across the entire data frame
df_range_all <- range(df, na.rm = TRUE)
print(df_range_all)  # Outputs: 1 6

# Get the range for column A
df_range_A <- range(df$A, na.rm = TRUE)
print(df_range_A)  # Outputs: 1 5

5. Using `range()` with Character Vectors

While its primary use is with numeric data, you can also use range() with character vectors, in which case it returns the minimum and maximum values lexicographically.

chars <- c("apple", "banana", "cherry")

# Get the lexicographical range
char_range <- range(chars)
print(char_range)  # Outputs: "apple" "cherry"

Conclusion

The range() function in R offers a straightforward way to identify both the smallest and largest values in your data set simultaneously. Its ability to handle different data structures and account for missing values makes it a handy tool in your R data analysis toolkit.
