Fast approximation
fast.approx(time, new.time, equal = FALSE, type = c("nearest", "right", "left"), sorted = FALSE, ...)
Original ordered time points
New time points
If TRUE a list is returned with additional element
Type of matching, nearest index, nearest greater than or equal (right), number of elements smaller than y otherwise the closest value above new.time is returned.
Set to true if new.time is already sorted
Optional additional arguments
# NOT RUN { id <- c(1,1,2,2,7,7,10,10) fast.approx(unique(id),id) t <- 0:6 n <- c(-1,0,0.1,0.9,1,1.1,1.2,6,6.5) fast.approx(t,n,type="left") # }
