I would like to make a condition considering the dataset below. I believe that the if
condition can be used, if not, it can be another way.
I would like to make a condition as follows:
If my chosen date2
is greater than date1
(date1
will always be just a single date, as you can see in my df datase
t) the calculation will be as follows: date2 - date1 + 1 = X -> this X will be the amount of DR columns that will be deleted from my df dataset
.
I will present the code of my df dataset
and then an example for you to see.
df <- structure(
list(date1 = c("2021-06-28","2021-06-28","2021-06-28","2021-06-28","2021-06-28",
"2021-06-28","2021-06-28","2021-06-28"),
date2 = c("2021-04-02","2021-04-03","2021-04-08","2021-04-09","2021-04-10","2021-07-01","2021-07-02","2021-07-03"),
Week= c("Friday","Saturday","Thursday","Friday","Saturday","Thursday","Friday","Monday"),
DR01_PV = c(4,1,4,3,3,4,3,6), DR02_PV= c(4,2,6,7,3,2,7,4),DR03_PV = c(9,5,4,3,3,2,1,5),
DR04_PV = c(5,4,3,3,6,2,1,9),DR05_PV = c(5,4,5,3,6,2,1,9),
DR06_PV = c(2,4,3,3,5,6,7,8),DR07_PV = c(2,5,4,4,9,4,7,8)),
class = "data.frame", row.names = c(NA, -8L))
df
date1 date2 Week DR01_PV DR02_PV DR03_PV DR04_PV DR05_PV DR06_PV DR07_PV

Example:
If I choose 01/07 (date2
), which is a date greater than date1
(28/06), we have the following:
date2 - date1 + 1 = X
01/07 - 28/06 + 1 = 3 + 1 = 4
This 4 means that the first 4 DR columns will be deleted from my df dataset
, ie DR01_PV, DR02_PV, DR03_PV and DR04_PV. My new dataset (df1
) will then be:
df1
date1 date2 Week DR05_PV DR06_PV DR07_PV
1 2021-06-28 2021-04-02 Friday 5 2 2

8 2021-06-28 2021-07-03 Monday 9 8 8
If I choose 02/07 (date2
), which is a date greater than date1
(28/06), we have the following:
date2 - date1 + 1 = X
02/07 - 28/06 + 1 = 4 + 1 = 5
This 5 means that the first 5 DR columns will be deleted from my df dataset
, ie DR01_PV, DR02_PV, DR03_PV, DR04_PV and DR05_PV. My new dataset (df2
) will then be:
df2

I tried to insert exampl to be more understandable.
Every help is welcome!
Thank you very much!
