Has anyone had problems with Rapache that don't show up on command line
execution of R? I just ran into this loading rgdal in Rapache page and having

Hi,
How can I discern which elements in x (see below) are in 'order', but more
specifically.. only the 1st 'ordered run'?
I would like for it to return elements 1:8... there may be ordered values
after 1:8, but those are not of interest.
x - c(1, 2, 3, 4, 5, 6, 7, 8, 20, 21, 22, 45)
Thanks
Hi,
If an ordered run means the difference is between the ith and ith +
1 position is 1, then:
out - rle(diff(x))
?diff gives you the differences (i + 1) - (i), and then run length
encoding encodes how long a run of the same number is. In this case,
there first run is length 7.
rle() outputs
well.. the following works, but if you have another idea I am still
interested.
1:(which(diff(x)!=1)[1])

Yeah. Right. A chi-squared test. That certainly narrows it down ...
