HYPEtools (version 1.6.4)

MergeObs: Merge two HYPE observation data frames

Description

Function to merge two HYPE observation data frames, with handling of overlapping time periods and time periods gaps as well as merging of common columns.

Usage

MergeObs(x, y)

Value

MergeObs returns a data frame with merged Obs data.

Arguments

x, y

Data frames containing observation timeseries data. Typically imported using ReadObs.

Details

MergeObs handles time steps of different lengths (e.g. daily, hourly), but requires identical time step lengths from both inputs data frames.

In case of common columns (identical date and SUBID combinations in x and y), values from columns in x will take precedence, and values from y will only be added if x values are missing.

Examples

# Import dummy data, add new observations to second Obs table, and merge
te1 <- ReadObs(filename = system.file("demo_model", "Tobs.txt", package = "HYPEtools"))
te2 <- ReadObs(filename = system.file("demo_model", "Tobs.txt", package = "HYPEtools"))
te2$X0000[1:365] <- runif(n = 365, -20, 25)
MergeObs(x = te1, y = te2)
