You can use the **as.Date()** function to convert a datetime to a date in R.

This function uses the following basic syntax:

df$date <- as.Date(df$datetime)

The following example shows how to use this syntax in practice.

**Example: Convert Datetime to Date in R**

Suppose we have the following data frame in R that contains information about sales made at some store:

#create data frame df <- data.frame(dt=as.POSIXct(c('2023-01-01 10:14:00 AM', '2023-01-12 5:58 PM', '2023-02-23 4:13:22 AM', '2023-02-25 10:19:03 PM')), sales = c(12, 15, 24, 31)) #view data frame df dt sales 1 2023-01-01 10:14:00 12 2 2023-01-12 05:58:00 15 3 2023-02-23 04:13:00 24 4 2023-02-25 10:19:00 31

The **dt** column contains the date and time of the sale.

We can use the **class()** function to view the class of this column:

#view class of dt column class(df$dt) [1] "POSIXct" "POSIXt"

We can see that the **dt** column currently has a class of POSIXct, which is a datetime class.

To convert this column to a date, we can use the **as.Date()** function:

#convert dt column to date df$dt <- as.Date(df$dt) #view updated data frame df dt sales 1 2023-01-01 12 2 2023-01-12 15 3 2023-02-23 24 4 2023-02-25 31

Notice that the time has been dropped from each datetime value in the **dt** column.

We can verify that the **dt** column now has a date class by using the **class()** function:

#view class of dt column class(df$dt) [1] "Date"

We can see that the **dt** column is indeed a date now.
