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)
