Hi,
The conditions are not very clear. Based on the rows you wanted to pick, may
be this helps,
#It is better to dput() the example.
dat <- structure(list(Date = structure(c(14610, 14611, 14612, 14613,
14614, 14615, 14616, 14617, 14618, 14619, 14620, 14621, 14622,
14623, 14624, 14625, 14
Hi Christoph,
I'm not sure I understand your conditions. It is an "AND" or an "OR",
i.e. must both conditions be met to subset or any one of them?
From your explanation, I would think you really mean AND, but then I

Hello,
I want to subset a data.frame containing the variables "Date" in (%Y %m %d
) and "N".
I want to print "Date" and "N" if N is less than or equal to 0.3 and if
"N" is also less than or equal to 0.3 on the day before the day where "N"
is less than or equal to 0.3.
This would be the case in
6 matches
