[Yovanov]

Hi!, i don't how to solve this problem:

texto_token = texto %>%

Can you provide a reprex or something so that we can work with some data?

[Yovanov]

No don't know how to use reprex on this web site, but i try to write all the code. I think that this error derives from the package.

library(pdftools)
library(tidyverse)
library(tidytext)

texto = pdf_text("/home/y---p---/Downloads/morel.pdf")

for (i in 1:length(texto)) {
texto[i] = str_replace_all(texto[i],"\n", "")
}

texto_token = texto[1] %>%
unnest_tokens(ngram, txt, token = "ngrams", n = 2)

The book that i analyze is morel.pdf (454.6 KB)

A minimal REPRoducible EXample (reprex) makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
