  verbose = getOption("ligerVerbose", TRUE),
  ...
)

importBMMC(
  dir = getwd(),
  overwrite = FALSE,
  method = "libcurl",
  verbose = getOption("ligerVerbose", TRUE),
  ...
)

importCGE(
  dir = getwd(),
  overwrite = FALSE,
  method = "libcurl",
  verbose = getOption("ligerVerbose", TRUE),
  ...
)

Arguments
