subset dataset based on date comparison R

Question

I have a dataset as shown below

    Col1      Col2       Col3        CutoffDate
    12001     Yes        2008-08-15  2008-08-10
    12001     Yes        2008-08-         


        

Answer 1

And if you are using dplyr:

library(dplyr)
df <- data.frame(Col1 = c(12001, 12001, 12001, 12001),
                 Col2 = c("Yes", "Yes", "Yes", "Yes"),
                 Col3 = as.Date(c("2008-08-15", "2008-08-22", "2008-08-10", "2008-08-04")),
                 CutoffDate = as.Date(c("2008-08-10", "2008-08-10", "2008-08-10", "2008-08-10")))

df %>% filter(Col3 <= CutoffDate)
