Hello,
how can one merge
And what happened when you typed:
?merge
two data frames when in the second data frame one column defines the
start values
and another defines the end value of the to be merged range.
data.frame.1
time ...
13
24
35
46
55
...
data.frame.2
start end
24 37 ?h? ?
...
should result in this
13 NA
24 ?h?
35 ?h?
46 NA
55
?
And _why_ would that be?
thanks,
René
