Call to deprecated `x$ntokens` in `textplot_xray.R`

[aurelberra]

To use an older script I am learning about the 3.0 version of quanteda and its companion packages.

I see that textplot_xray.R raises the following warning:

Use of x$ntokens is discouraged. Use ntokens instead.

Leaving an issue here, although I am sure you will at some point update your code.

We'd need to see your complete code and output to know what is happening here, including your package version numbers. Can you add those please?

[aurelberra]

Of course. I am using the latest versions. Here is a minimal example.

The text is the Iliad, and the keyword is Achilles' name.

library(quanteda, quanteda.textplots)

test <-
  read_lines("data/homer/homer_perseus_lem/iliad_perseus_lem_books.txt")

test <- corpus(test)
test <- tokens(test)

kwic(test, pattern = "ἀχιλλεύς") |>
  textplot_xray()

The environment is the following:

R.version.string

[1] "R version 4.1.1 (2021-08-10)"

RStudio.Version()$version

[1] ‘1.4.1717’

Sys.info()

sysname "Darwin" release "20.6.0" version "Darwin Kernel Version 20.6.0: Mon Aug 30 06:12:21 PDT 2021; root:xnu-7195.141.6~3/RELEASE_X86_64"

pacman::p_loaded() %>%
  sort() %>%
  map(~ paste0(., " v", pacman::p_version(.))) %>%
  str_match_all("quanteda.*") %>%
  unlist()

[1] "quanteda v3.1.0" "quanteda.textplots v0.94"

The output is a normal graph in RStudio's "Plots" pane and this warning in the console:

Warning message: Use of x$ntokens is discouraged. Use ntokens instead.

Can you supply a link to iliad_perseus_lem_books.txt so I can try to reproduce this warning?

[aurelberra]

I could, but I thought an even simpler example would be an easier way for you to test. I have the same warning with the following code:

library(tidyverse)
library(quanteda)
library(quanteda.textplots)

test <- "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Lorem ipsum dolor sit amet, consectetur adipiscing elit."
test <- corpus(test)
test <- tokens(test)

kwic(test, pattern = "ipsum") |>
  textplot_xray()

I get this in the console:

Warning message: Use of x$ntokens is discouraged. Use ntokens instead.

Thanks, got it. I'll track it down and stop the warning shortly.
