Hi Jeff,
As I'm sure you realize, that only tells you whether a date is within
the range that you have specified. Do you only want to find dates
within a certain range:
new_date<-as.Date("2020-01-10")
new_date < min(d) | new_date > max(d)
or maybe whether the text string specifying the date is
Looks reasonable and efficient. There is a seq.Date function that would be
implicitly selected by the S3 class dispatch rules

I have a 20 year data set and I am looking for a way to find missing dates.
I wrote this and its works, but am wounding if there is a better way?
d <- c('2020-01-01', '2020-01-02', '2020-01-04', '2020-01-05')
d <- as.Date(d)
date_range <- seq(min(d), max(d), by = 1)
date_range[!date
