Upload an EPUB file in R

Question

I'm trying to read an EPUB file in r. It is placed in the working directory. I wrote this code:

library(epubr)
library(tm)
x <- epub("Perchisuonalacampana.epub") # parse entire e-book

But I obtained the following error:

Error in file.exists(path) : 
 file name conversion problem -- name too long?

(My EPUB file contains a novel.)

EDIT

getwd()
[1] "C:/Users/Standard/Downloads/aaa"
list.files()
[1] "dtm from pdf.R"            "Perchisuonalacampana.epub"

Are you sure that that file comes with the package? This works: `file <- system.file("dracula.epub", package = "epubr")`. — Rui Barradas, Nov 08 '20 at 12:18
Yes, but I have stored a file, Perchisuonalacampana.epub, on my directory. I thought it also worked for different files — Mark, Nov 08 '20 at 13:58
If it's *your* file then it's not a *system* file, meaning, a data file packaged with `epubr`. Try just `epub("path/to/Perchisuonalacampana.epub")`. — Rui Barradas, Nov 08 '20 at 16:38
Thank you, but I obtained: Error in file.exists(path) : file name conversion problem -- name too long? — Mark, Nov 08 '20 at 21:47
Change to the directory where the file is and try just the filename, there will be n need for a full pathname. — Rui Barradas, Nov 08 '20 at 22:32

Can you change the file + folder names to something simple? I wonder if the file name has some weird characters — Alex Joseph, Nov 14 '20 at 20:02
Try change version file https://ebook.online-convert.com/convert-to-epub — Adrian Romero, Nov 17 '20 at 17:24

From these two sources (they are nearly the same):

It seems as though you need to do add the system.file():

library(epubr)
library(tm)

file <- system.file("Perchisuonalacampana.epub", package = "epubr")
x <- epub(file) # parse entire e-book

Not sure if these help any more but here are two more sources for a slightly different approach:
