1d:T762,# ctbi.timeseries Calculate the sequence of bin sides that encompasses the original time series based on a bin period and a bin side (or a bin center). The sequence of bin centers is calculated as well. ```r ctbi.timeseries(x.t, bin.period, bin.side, bin.center = NULL) ``` ## Arguments - `x.t`: original time series (date, POSIXct or numeric) - `bin.period`: time interval between two sides of a bin. If x.t is numeric, bin.period is numeric. If x.t is POSIXct or Date, bin.period = 'k units', with k an integer and units = (seconds, minutes, hours, days, weeks, half-months, months, years, decades, centuries, millenaries) - `bin.side`: one side of a bin (same class as x.t) - `bin.center`: if bin.side is not specified, one center of a bin (same class as x.t) ## Returns A list that contains: seq.bin.side, the sequence of bin sides (same class as bin.side) seq.bin.center, the sequence of bin centers (same class as bin.side) time.step.median, the median time step (numeric) ## Examples ```r x.t <- seq(from=as.Date('2001-01-01'),to=as.Date('2010-12-01'),by='1 month') bin.side <- as.Date('2003-10-01') bin.period <- '4 months' list.ts <- ctbi.timeseries(x.t,bin.period,bin.side) seq.bin.side.Date <- list.ts$seq.bin.side seq.bin.center.Date <- list.ts$seq.bin.center x.t <- seq(from=as.POSIXct('2001-01-01 12:45:23'),to=as.POSIXct('2001-01-01 13:34:21'),by='18 s') bin.side <- as.POSIXct('2001-01-01 13:00:00') bin.period <- '1 minute' # '60 s', '60 sec', '60 seconds', '1 min' are also possible list.ts <- ctbi.timeseries(x.t,bin.period,bin.side) seq.bin.side.POSIXct <- list.ts$seq.bin.side seq.bin.center.POSIXct <- list.ts$seq.bin.center x.t <- seq(from= - 50000,to= 2000 ,by=1000) bin.side <- 0 bin.period <- 10000 list.ts <- ctbi.timeseries(x.t,bin.period,bin.side) seq.bin.side.numeric <- list.ts$seq.bin.side seq.bin.center.numeric <- list.ts$seq.bin.center ```
