Example of RunModel_Lag to improve

While LengthHydro is supposed to be in m (see help of CreateInputsModel), the example of Runmodel_Lag gives a value of 150 km.

In addition, I don't see any difference in the result when I multiply the Lag parameter by 1000. Is that normal?

added DOC label

The difference is subtle because Qupstream is constant the most of the time so shifting it not resulting in big in changes in downstream flow.

Look at the signal of Qupstream:

library(airGR)
example("RunModel_Lag")
plot(OutputsModel$DatesR, Qupstream[RunOptions$IndPeriod_Run], type = "l")

And look at the difference between output of normal Lag and Lag * 1000:

QsimLag <- OutputsModel$Qsim
OutputsModel <- RunModel_Lag(InputsModel = InputsModel,
                             RunOptions = RunOptions, Param = Lag * 1000)
plot(OutputsModel$DatesR, QsimLag - OutputsModel$Qsim, type = "l")

Difference only occur when Qupstream changes (around twice a year).

Normally, the tests in https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/blob/dev/tests/testthat/test-RunModel_Lag.R ensure that the lag calculation is correct. You can check the tests or propose new tests if you have a doubt.

Sorry, my mistake! I knew I had to be wrong but I didn't know why... :/

(My comment about the unit of LengthHydro is still valid! )

I corrected miscellaneous mistakes in the RunModel_Lag.Rd file.
