add withdrawl argument to nhanesSearchTableNames

[Ifitrains]

nhanesA::nhanesSearchTableNames("PAHS", details = TRUE) returns,

      Years                                                  Data.File.Name   Doc.File

3 PAHS_I Data [XPT - 310.7 KB]      July 2020

Withdrawn datasets are not really useful and cannot be downloaded from the nhanes() function, so it would be very nice to have an option to automatically remove withdrawn datasets from the search.

Thanks for submitting this. I'll take a look but may not get to it until after Thanksgiving.

Just pushed a fix to git.
nhanesSearchTableNames now has option includewithdrawn.

Please install the update using: install_github("cjendres1/nhanes")
It will install as nhanesA 0.7.2

By default, includewithdrawn=FALSE. Thus Withdrawn tables should not show up when you run your previous command.
nhanesSearchTableNames("PAHS", details = TRUE)

Please test the function with these commands:

nhanesSearchTableNames("PAHS",  includewithdrawn = TRUE, details = TRUE) 
nhanesSearchTableNames("PAHS",  includewithdrawn = FALSE, details = TRUE)

Fix included in nhanesA 0.7.2
