Other arguments to be passed.

Value

an IFC_data object with regions added.

Examples

# NOT RUN {
if(requireNamespace("IFCdata", quietly = TRUE)) {
  ## use a daf file
  file_daf <- system.file("extdata", "example.daf", package = "IFCdata")
  daf <- ExtractFromDAF(fileName = file_daf)
  ## copy 1st region found in daf
  reg <- daf$regions[[1]]
  if(length(reg) != 0) {
    reg_copy <- reg
    ## modify region label and x boundaries
    reg_copy$label <- paste0(reg_copy$label,"_copy")
    reg_copy$x <- reg_copy$x*0.9
    ## create new object with this new region
    dafnew <- data_add_regions(obj = daf, regions = list(reg_copy))
  }
} else {
  message(sprintf('Please run `install.packages("IFCdata", repos = "%s", type = "source")` %s',
                  'https://gitdemont.github.io/IFCdata/',
                  'to install extra files required to run this example.'))
