Greetings! I am analysing my data and checking for gaps over 1 hour and come across the problem that R tells me that there are many 2 hour gaps. When I go into details, I don't see any of these lapses. Is it something with the diff() function?
You can see what I am saying, below: M<-matrix(c(1999,10,31,1, 1999,10,31,2, 1999,10,31,3, 1999,10,31,4),4,4,byrow=T) colnames(M)<-c("YY","MM","DD","HH") time<-ISOdatetime(M[,"YY"],M[,"MM"],M[,"DD"],M[,"HH"],0,0) print(diff(time)) >Time differences in hours [1] 1 2 1 Has anyone ever seen something like this? I mean, diff() is one of the basic functions of R, so it is probable that many people has seen something similar, before. However, somehow, I can't find an answer string on stackexchange or analogous pages.
