Update parameter in the scenario by adding data to it

Update parameter in the scenario by adding data to it

Usage

update_parameter(object, param, data, path = NULL)

Arguments

object

scenario object

param

character, name of the parameter to update

data

data.frame, data to update the parameter with

path

character, path to the parameter on disk, if NULL, the function will try to create the path from the path to parameters in scen@modInp@parameters and the name of the parameter.

Value

the updated scenario object, invisibly.

Examples

# \donttest{
ek   <- topia$modules$electricity$R3
mod  <- newModel("TOPIA", data = ek$repo,
                 calendar = topia$modules$calendars$s4_h24,
                 region = ek$regions,
                 horizon = topia$modules$horizons$base,
                 discount = 0.05)
mod <- setGeoscale(mod, ek$geoscale)
scen <- interpolate_model(mod, name = "EX")
#> Cost declared at a coarse geoscale level:
#>   TBD_COA_WEST_CENTRAL@invcost: CENTRAL, WEST
#>   TBD_GAS_WEST_CENTRAL@invcost: CENTRAL, WEST
#> The cost is charged ONCE at that cell rather than at each child region, and is discounted at the children's rate. That is usually what a national cost datum means -- said here because it is a different number from naming the children individually.

# write one parameter back after editing it outside the model. The data
# must carry exactly the parameter's own columns -- `getData()` adds the
# scenario name and the variant provenance, which are not part of it.
af <- as.data.frame(getData(scen, "pTechAf", merge = TRUE))
af <- af[, c("tech", "region", "year", "timeslice", "type", "value")]
af$value <- af$value * 0.98

scen <- update_parameter(scen, "pTechAf", af)
# }
