Question
I'm trying to extract data from a pdf document that contains tables with checkboxes (see my reproducible example below).
The extract_tables() function works well and manages to identify the tables in the pdf document, but I only get NA for all the checkboxes.
Is there any way of identifying which boxes are checked?
Many thanks for your help ! 🙏
Reproducible example
Here's my pdf
test.pdf
And my code :
library(tabulapdf)
fichier <- "test.pdf"
tableaux <- extract_tables(fichier, output = "tibble")
bases_de_conjoncture <- tableaux[[1]]
sources <- tableaux[[2]]What I get :
# A tibble: 33 × 3
`CERISE (Espace de Production des données)` ...2 ...3
