Remove error values manually

Description

'remove_manually()' removes unreasonable values manually by indicating specific timestamps.

Usage

remove_manually(vctr_time, vctr_target, vctr_time_err, label_err = -9999)

Arguments

vctr_time	A timestamp vector of class POSIXct or POSIXlt.
vctr_target	A vector of a targeted time series to be checked. The length of the time series must be the same as that of 'vctr_time'.
vctr_time_err	A timestamp vector of class POSIXct or POSIXlt, indicating specific error timings.
label_err	A numeric value representing a missing value in the input vector(s). Default is -9999.

Value

A vector of cleaned time series. The length of the time series is the same as the input time series. The data points at the indicated time points by 'vctr_time_err' are replaced with the error label specified in 'label_err'.

Examples

## Load data
data(dt_noisy)
time <- dt_noisy$time[12097:14400]
target <- dt_noisy$dt[12097:14400]
time_err <- seq(as.POSIXct("2013/06/27 18:00", tz = "Etc/GMT-8"),
                as.POSIXct("2013/06/27 22:30", tz = "Etc/GMT-8"),
                by = "30 min")

## Remove error values
result <-
 remove_manually(vctr_time = time, vctr_target = target,
                 vctr_time_err = time_err)
