How to create a sequence of dates by using starting date in R?

The best way to create a sequence of anything is creating it with the help of seq function and this also applies to sequences of dates. But in case of dates, we need to read the dates in date format so that R can understand the input type and create the appropriate vector. If we do not use the date format for the date value then it won’t make sense to R and it will result in error.

x1<-seq(as.Date("2020-01-01"),by="day",length.out=5)
x1

Output

[1] "2020-01-01" "2020-01-02" "2020-01-03" "2020-01-04" "2020-01-05"
