Usage

Gemini with AI Studio API

Text

library(gemini.R)

setAPI("your API key") # check https://makersuite.google.com/app/apikey
gemini("Explain about the gemini in astrology in one line")

# text
# "Gemini, the third astrological sign, is associated with
# communication, adaptability, and a thirst for knowledge."

Image

# uses default prompt as "Explain this image"
# uses included image of gemini.R package
gemini_image(image = system.file("docs/reference/figures/image.png", package = "gemini.R"))

# text
# " The image shows a table with a white tablecloth. On the table are two cups of coffee,
# a bowl of blueberries, and five scones. The scones are covered in blueberries and have
# a crumbly texture. There are also some pink flowers on the table. The background is a
# dark blue color. The image is taken from a top-down perspective."

Audio

# use default prompt as "Describe this audio"
# uses included audio of gemini.R package
gemini_audio(audio = system.file("docs/reference/helloworld.mp3", package = "gemini.R"))

# text
# "The audio contains a clear, crisp recording of a person saying \"Hello world\".
# Following the phrase is a distinct, repeated percussive sound, possibly a rhythmic
# tapping or clicking noise. The sound is consistent and mechanical in nature.\n"

Image via Shiny

To use gemini_image function, image file required. and I recommend to use shiny app with fileInput function.

library(shiny)
library(gemini.R)

setAPI("YOUR KEY")
ui <- fluidPage(
  sidebarLayout(
    NULL,
    mainPanel(
      fileInput(
        inputId = "file",
        label = "Choose file to upload",
      ),
      imageOutput(outputId = "image1"),
      textInput(
        inputId = "prompt",
        label = "Prompt",
        placeholder = "Enter Prompts Here"
      ),
      actionButton("goButton", "Ask to gemini"),
      textOutput("text1")
    )
  )
)

server <- function(input, output) {

  observeEvent(input$file, {
    path <- input$file$datapath
    output$image1 <- renderImage({
      list(
        src = path
      )
    }, deleteFile = FALSE)
  })

  observeEvent(input$goButton, {
    output$text1 <- renderText({
      gemini_image(input$prompt, input$file$datapath)
    })
  })
}

shinyApp(ui = ui, server = server)

Gemini with Vertex AI API

Text

tokens <- token.vertex("YOUR_API_KEY.json", model_id = "1.5-flash")
prompt <- "What is sachins Jersy number?"

gemini.vertex(prompt, tokens)

Image

tokens <- token.vertex("YOUR_API_KEY.json", model_id = "1.5-flash")

gemini_image.vertex(image = "YOUR_IMAGE.png", type, tokens)

Audio

tokens <- token.vertex("YOUR_API_KEY.json", model_id = "1.5-flash")

gemini_audio.vertex(audio = "YOUR_AUDIO.mp3", tokens)

• File upload to Google Cloud using API not supported.
• Instead you must use uploaded file. (e.g. Google Cloud Storage)
• Example sound from soundbible

Image generation

gen_image('Draw an image of a cat swimming in the Milky Way')

Rstudio Addins

Function documentation (Roxygen)

You may customize keyboard shortcut for this feature.

Unit testing (testthat)

Terms

Before use the API, I recommend that you to check at least the following.

• Google Cloud Platform Terms of Service
• Gemini API Additional Terms of Service

There may be more terms and conditions that you need to check. Any app which uses the API should be compliant with the Google Terms of Service.
