Installation

To install the package:

```{r}

The easiest way is to get polyglotr from CRAN

install.packages("polyglotr")

Alternatively, install the development version from GitHub

install.packages("remotes")

remotes::install_github("Tomeriko96/polyglotr") ```

Quick Start

Here's a minimal example to get you started:

``` library(polyglotr)

Translate a simple phrase using Google Translate

text <- "Hello, world!" translation <- googletranslate(text, targetlanguage = "fr") print(translation)

Translate using Apertium (no API key required)

translationapertium <- apertiumtranslate(text, targetlanguage = "es", sourcelanguage = "en") print(translation_apertium)

```

Shiny Web App

polyglotr includes a web application for translation services, accessible to users without R programming knowledge.

Launching the App

```r library(polyglotr) launchpolyglotrapp()

Or with custom settings

launchpolyglotrapp(port = 3838, launch.browser = TRUE) ```

App Features

• Multiple translation services: Google Translate, MyMemory, PONS, Linguee, QCRI, Apertium, Wikimedia Cloud
• Language detection
• Dynamic language selection based on service
• User-friendly dashboard interface
• No coding required

Installation Requirements

To use the Shiny app, install these additional packages:

r install.packages(c("shiny", "shinydashboard", "DT"))

Usage

To demonstrate the usage of the polyglotr package, let's consider an example where we translate a list of texts into multiple languages using the create_translation_table function.

```{r} texts <- c("Hello, how are you?", "I love programming!", "This is a test.")

languages <- c("es", "fr", "de")

createtranslationtable(texts, languages)

> Original_word es

> 1 Hello, how are you? ¿Hola, cómo estás?

> 2 I love programming! ¡Me encanta programar!

> 3 This is a test. Esto es una prueba.

> fr de

> 1 Bonjour comment allez-vous? Hallo, wie geht's dir?

> 2 J'adore programmer ! Ich liebe Programmieren!

> 3 C'est un test. Das ist ein Test.
