A vector is a one-dimensional data structure used to store data of the same type in R. Numeric vectors are commonly used to store a sequence of numbers. In this tutorial, we will look at how to get the minimum value in an R vector with the help of some examples.
How to get the min value in a vector in R?

You can use the R min()
function to get the minimum value in a vector. Pass the vector as an argument to the function. The following is the syntax –
# get the max value in a vector max(x, na.rm=FALSE)
The following are the arguments that you can give to the min()
function in R.
- x – The vector for which you want to compute the min value.
- na.rm – (Optional argument) Indicates whether to remove missing values before computing the minimum. It is
FALSE
by default.
The function returns the min value in the passed vector.
Examples
Let’s look at some examples of using the above method to get the min value in a vector.
Minimum value in a numeric vector
Let’s create a vector of numbers (and without any NA
values) and apply the min()
function.
# create a vector of numbers vec <- c(3, 2, 5, 4) # min value in vector min(vec)
Output:
2
We get 2 as the max value in the above vector, which is the correct answer.
What would happen if there are some NA
present values in the vector?
Let’s find out.
First, we will create a vector with some NA
values and then apply the min()
function without any additional arguments.
# create a vector with NA values vec <- c(3, 2, NA, 5, NA, 4, NA) # min value in the vector min(vec)
Output:
<NA>
You can see that we get NA
as the output. This is because comparing a value with NA results in an NA
in R.
Minimum in a vector with NA
values
You can pass TRUE
to the na.rm
parameter of the max()
function to exclude missing values when computing the minimum value in a vector.
# create a vector with NA values vec <- c(3, 2, NA, 5, NA, 4, NA) # min value in the vector min(vec, na.rm=TRUE)
Output:
2
Now we get the minimum value in the above vector as 2.
Minimum value in a character vector
The min()
function also works similarly on a vector of characters. For example, let’s see what we get on applying the min()
function on a vector of characters.
# create a vector of chracters vec <- c("a", "b", "c", "d") # min value in the vector min(vec)
Output:
'a'
Here, we get ‘a’ as the minimum value in the above vector which contains the values ‘a’, ‘b’, ‘c’, and ‘d’.
