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 [[alternative HTML version deleted]]
