After extracting texts from pdf files, my variables contain literal \n and \\n. How can I remove them? I have tried form2_df$firm_new <- str_replace_all(form2_df$firm, "\\n", ""). But it did nothing.
Here is my dput output:

I took the liberty to clean more than you asked but I am not sure if it helps or makes it more difficult to understand the text.
