diff days R lubridate

First, we need to load the "lubridate" package in R by using the "library" function. This package provides a set of tools to work with dates and times in R.

Next, we need to create a vector of dates using the "seq" function. In this case, we want to generate a sequence of dates starting from "2019-01-01" to "2019-12-31" with a frequency of 1 day. We assign this sequence to the variable "date_seq".

To extract the day of the week from each date in our sequence, we use the "wday" function from the "lubridate" package. This function returns an integer representing the day of the week, where 1 is Sunday and 7 is Saturday. We pass the "date_seq" vector as an argument to the "wday" function and assign the result to the variable "day_of_week".

Lastly, we can print the "date_seq" vector and the "day_of_week" vector to see the dates and their corresponding day of the week.

Here is the code:

# Load the "lubridate" package
library(lubridate)

# Create a vector of dates
date_seq <- seq(as.Date("2019-01-01"), as.Date("2019-12-31"), by = "day")

# Extract the day of the week
day_of_week <- wday(date_seq)

# Print the dates and their day of the week
print(date_seq)
print(day_of_week)

I hope this explanation helps! Let me know if you have any further questions.
