[R] Choosing specific Date Range from non-sequential Date: Problem Fixed

[Ogbos Okike]

Dear Bert and Jeff,
The result is an output of another code and it will be too long or
unnecessary to show all I'm I did to arrive at the given data frame.

Since my single line code works for Jeff, I had to take a second look
and try to get it working for me. I then read the data frame using
d<-read.table("MOSC",colClasses=c("Date","numeric"))  and tried:
Year <- subset(d1, d1[[1]] > "1998-01-01" & d1[[1]] < "2006-01-01")
and arrived at my goal.

Thank you for the hint.
Best regards
Ogbos

As Bert recommended, you need to use the dput function rather than dumping numbers into the email if we are to know how your data are stored in memory which will affect what results you get. I highly recommend using the reprex package to verify that your example is reproducible.
