# Searchable Codebooks

    library(rfars)
    library(dplyr)
    library(stringr)

`rfars` comes pre-loaded with searchable codebooks, compiled from SAS format files and the User Manuals (see: FARS Analytical User’s Manual and CRSS Analytical User’s Manual). Access the codebooks in RStudio with:

    View(rfars::fars_codebook)
    View(rfars::gescrss_codebook)

It can be helpful to search the codebooks for certain concepts. For example, below we print out all entries related to speed. This helps find relevant crashes for analysis and shows how variables change over time.

    rfars::fars_codebook %>%
      filter(if_any(everything(), ~ str_detect(as.character(.), "speed"))) %>%
      DT::datatable(caption = "Codebook records pertaining to speed")
