R-users,
I have two vectors (of timestamps)
d1 <- as.POSIXct(strptime("2.2.2002 07:00", format="%d.%m.%Y %H:%M"))
d2 <- as.POSIXct(strptime("4.2.2002 07:00", format="%d.%m.%Y %H:%M"))
seq1 <- seq(d1, d2, "hours")
seq1
d3 <- as.POSIXct(strptime("2.2.2002 15:22", format="%d.%m.%Y %H:%M"))
d4 <- as.POSIXct(strptime("3.2.2002 18:12", format="%d.%m.%Y %H:%M"))
seq2 <- seq(d3, d4, "hours")
seq2
How to select timestamps from seq1 which are just before and after of
particular timestamp in seq2?
The resulting vector should look like this in this example:
"2002-02-02 15:00:00 Normaaliaika"
"2002-02-02 16:00:00 Normaaliaika"
"2002-02-02 16:00:00 Normaaliaika"
"2002-02-02 17:00:00 Normaaliaika"
"2002-02-02 17:00:00 Normaaliaika"
"2002-02-02 18:00:00 Normaaliaika"
"2002-02-02 18:00:00 Normaaliaika"
etc.
Thank you,
Lauri
