Hi Livia, >From your description, it sounds like the "time" variable is actually a vector of date strings like "30/04/2015". These will usually be input as "factors" in R, meaning that you probably had a very large number of categorical values instead of numeric. To find out, do this:
is.factor(time_variable) where "time_variable" is something like mydata$Time. If the answer is TRUE, convert that variable to a vector of dates with as.Date and try your analysis again.
