Package tabloToR

A package that can interpret GEMPACK-style TABLO models in R and solve them

To install, you can try the following:

install.packages('devtools')
devtools::install_git('https://github.com/mivanic/tabloToR.git')

To perform a simulation, you can try the following:

model = tabloToR::GEModel$new()

# You need to have the model, such as gtap.tab 
model$loadTablo('gtap.tab')

# You need to get the data files .har
data = list(
  # The file with GTAP sets may alternatively be called sets.har by some data aggregation programs
  gtapsets = HARr::read_har('gsdgset.har'),
  # The file with GTAP parameters may alternatively be called default.prm by some data aggregation programs
  gtapparm = HARr::read_har('gsdgpar.har'),
  # The file with GTAPdata may alternatively be called basedata.har by some data aggregation programs
  gtapdata = HARr::read_har('gsdgdat.har')
)

# Initialize the model object

model$loadData(data)

# Set up the closure
