Hi,
I'm currently facing the problem that I need to write a function where I get a
dataframe back which contains the time (in hours) outside the limits of a
temperature sensor, each month, and for how long exactly.
I wrote a for loop which check:- if a datapoint is outside the limit- if the
previous datapoint is outside the limt, then count + 1- if the next datapoint
isn't outside: write in dataframe.
I guess this could be with some vectorisation function, I tried with seq_along,
and match, but couldn't figure it out.
Here some sample data:
y <- c(rnorm(10,25), rnorm(10,32),rnorm(10,25), rnorm(10,20), rnorm(10,25))x <-
seq(c(ISOdate(2000,3,20)), by = "hour", length.out = length(y))
limits of y: c(22,27)
Thanks
Bart
