Type cast to date in R – Text to Date in R , Factor to date in R

In Order to type cast to date in R we will be using as.Date() function. Let’s see how to type cast a text to date in R or factor to date in R with an example using as.date function.

Let’s first create the dataframe.

### Create Data Frame

df1 = data.frame (
  Name =c('Annie','Catherine','Teresa','Peterson','Richard','Joe'),
  Date_of_birth =c('1995-06-16','1991-04-19','1993-07-22','1990-03-26','1991-05-12','1992-09-13'))

df1

So the resultant dataframe will be

Type cast to date in R – Text to Date 1

Let’s check the current data type of date_of_birth column.

# Get data type of column

sapply(df1,class)

So the data types will be

Type cast to date in R – Text to Date 2

 

Type cast to date in R:

Date_of_birth column is type casted using as.Date function as shown below

# Type cast the column to date

df1$Date_of_birth <- as.Date(df1$Date_of_birth)
sapply(df1,class)

As the result the Date_of_birth column is type casted to date .

Result:

Type cast to date in R – Text to Date 3
