read_freqlist: Read a frequency list from a csv file

In mclm: Mastering Corpus Linguistics Methods

Read a frequency list from a csv file

Description

This function reads an object of the class freqlist from a csv file. The csv file is assumed to contain two columns, the first being the type and the second being the frequency of that type. The file is also assumed to have a header line with the names of both columns.

Usage

read_freqlist(file, sep = "\t", file_encoding = "UTF-8", ...)

Arguments

file	Character vector of length 1. Path to the input file.
sep	Character vector of length 1. Column separator.
file_encoding	File encoding used in the input file.
...	Additional arguments (not implemented).

Details

read_freqlist not only reads the file file, but also checks whether a configuration file exists with a name that is identical to file, except that it has the filename extension ".yaml".

If such a file exists, then that configuration file is taken to 'belong' to file and is also read and the frequency list attributes "tot_n_tokens" and "tot_n_types" are retrieved from it.

If no such configuration file exists, then the values for "tot_n_tokens" and "tot_n_types" are calculated on the basis of the frequencies in the frequency list.

Value

Object of class freqlist.

Examples

toy_corpus <- "Once upon a time there was a tiny toy corpus.
It consisted of three sentences. And it lived happily ever after."
freqs <- freqlist(toy_corpus, as_text = TRUE)

print(freqs, n = 1000)

write_freqlist(freqs, "example_freqlist.csv")
freqs2 <- read_freqlist("example_freqlist.csv")
print(freqs2, n = 1000)
