Compose URLs — compose

Compose URLs to TRS PDFs for JECFA reports. Valid URLs are constructed based on the JECFA data frame information, i.e, they should report "NOT FAS" or "NOT PREPARED" in the Tox_monograph_abbr column and have a valid URL in the Report_sourcelink column.

Usage

compose_urls(jecfa)

Arguments

jecfa: a data frame with the JECFA data

Value

a list with the URLs specification for each JECFA report, i.e., a list with the URL, the filename with the ID and the filename without the ID

Examples

library(jecfa)

# first element will be NULL because report 1 has no PDF, while
# record 2 has a PDF so it will be a list with the URL, the filename
# with the ID and the filename without the ID.
