Convert flows units

Usage

convertUnitQ(x, ...)

# S3 method for data.frame
convertUnitQ(x, areas, from, to, ...)

Arguments

x

a data.frame with a first column with the time stamp in POSIXct format and folling columns with flows

...

Arguments passed to the methods

areas

named vector, basin areas in km², names must correspond to station ids in columns names of x

from

flow unit of x, see details

to

flow unit of returned values

Value

data.frame with a first column with the time stamp in POSIXct format and folling columns with converted flows

Details

Available units are:

• "mm" for mm per time step

• "m3" for m3 per time step

• "m3/s" for m3 per second

• "l/s" for liter per second

The time step is determined with the time difference between rows in x.

Examples

data("L0123001", package = "airGR")
dfQmm <- data.frame(DatesR = BasinObs$DatesR, L0123001 = BasinObs$Qmm)
dfQls <- convertUnitQ(dfQmm, c(L0123001 = BasinInfo$BasinArea), from = "mm", to = "l/s")
head(dfQls)
