Get or Set the Type of an Object in R Programming - mode() Function

Last Updated : 19 Jun, 2020

mode() function in R Language is used to get or set the type or storage mode of an object.

Syntax: mode(x) mode(x) <- value Here "value" is the desired mode or ‘storage mode’ (type) of the object Parameters: x: R object

Example 1:

Python3

# R program to illustrate
# mode function

# Initializing some values
x <- 3
y <- "a"

# Calling the mode() function 
mode(x)
mode(y)

Output:

[1] "numeric"
[1] "character"

Example 2:

Python3

# R program to illustrate
# mode function

# Initializing some values
x <- 3
y <- "a"

# Calling mode() function to
# set the storage mode of the object
mode(x) <- "character"
mode(y) <- "numeric"

# Getting the assigned storage mode
mode(x)
mode(y)

Output:

[1] "character"
[1] "numeric"
