Addon agency issue running with 5day weights about summarizenhts

[AnthonyFucci]

Thanks for reporting this! prepare_add_on_files() is kind of risky in that it's used very infrequently and does not have a warning to let the user know if specified directory has already been prepared as either 5 day or 7 day. It also needs to be called whenever the data is read in so that summarizeNHTS knows which weight type to use.

Try this method to see if it resolves the numbers. Update program first

devtools::install_github('Westat-Transportation/summarizeNHTS')

1. Create a 5 day directory and a 7 day directory. Copy the entire INCOG dataset into each so that you have two folders with the original dataset (e.g. "C:/NHTS/INCOG/5day/csv/2017" and "C:/NHTS/INCOG/7day/csv/2017")
2. Run prepare_add_on_files() twice, once for each directory.

prepare_add_on_files(
  directory = "C:/NHTS/INCOG/5day/csv/2017",
  weight_type = "5day"
)
prepare_add_on_files(
  directory = "C:/NHTS/INCOG/7day/csv/2017",
  weight_type = "7day"
)

3. Whenever you read in an add on dataset, run prepare_add_on_files() with only the weight_type parameter specified so that summarizeNHTS knows which to use

nhts_data <- read_data(
  dataset = "2017",
  csv_path = "C:/NHTS/INCOG/5day"
)
prepare_add_on_files(weight_type = "5day")

4. Now numbers should match other tools

summarize_data(
  data = nhts_data,
  agg = "trip_count",
  by = "WHYTRP1S"
)

Closing due to lack of activity.
