Improve Texts via Round-Trip Translation with the DeepL API Free

pimp2 translates a text into a helper language and then back to the original language using the DeepL API Free. This method can be used to refine or rephrase text automatically.

pimp2(text, source_lang, help_lang, auth_key)

Arguments

text

A character vector containing the texts to be improved. Only UTF-8 encoded plain text is supported. Each element may contain multiple sentences but should not exceed 30 kB.

source_lang

A string specifying the source language of the input text. If of length 1, the same language is applied to all elements.

help_lang

A string specifying the helper language used for the intermediate translation.

auth_key

A string representing the authentication key for the DeepL API Free. If not provided, the function will attempt to retrieve the key from the environment variable DEEPL_API_KEY. You can set this variable using Sys.setenv(DEEPL_API_KEY = "your_key") or define it in your .Renviron file for persistent use.

Details

To use this function, you must obtain an authentication key by registering for a DeepL API Free account at DeepL API Free. With the Free API, you can translate up to 500,000 characters per month at no cost. To view all supported languages, use available_languages2.
