我是 R 新手,我想从 PDF 中提取数据。在某些情况下,我按照教程设置 rJava,然后尝试运行代码:

pacman::p_load(
  rJava,
  tabulizer,
  tidyverse)

Df <- extract_tables(
  file   = "C:/Users/afons/Epidemiology2021/BOLETIM EPIDEMIOLÓGICO COVID_FMV_26Julho-8Agosto2021.pdf", 
  method = "decide", 
  output = "data.frame")

当我这样做时,我收到以下错误:

Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl,  : 
  java.lang.IllegalAccessException: class RJavaTools cannot access a member of class java.util.ArrayList$Itr (in module java.base) with modifiers "public"

这可能是什么原因造成的?这是一个 3 页 PDF,第 2 页上的表格带有标题

请帮忙
