Introduction

This vignette demonstrates the usage of the download_filtered_tableau_image function in the R package. We’ll use the Super Sample Superstore example in Tableau to showcase how to download filtered images by filtering on various combinations of region and category.

library(vvtableau)

# Authenticate on the Tableau Server.
tableau <- authenticate_server(
  server = "https://tableau.server.com",
  username = "your_username",
  password = "your_password"
)

# Set the view ID for the Super Sample Superstore example view
view_id <- "super-sample-superstore-view-id"

# Set the path to save the downloaded images
path_to_save <- "path/to/save/images/"

Download Filtered Images

Let’s download images for different combinations of region and category filters.

# Create a dataframe with the filter values for each combination
filter_df <- data.frame(
  region = c("West", "East", "Central"),
  category = c("Furniture", "Technology", "Office Supplies")
)

download_filtered_tableau_image(tableau, filter_df, view_id, path_to_save)

For this example, the function will iterate over each row of the dataframe and download the filtered images for each combination of region and category. In this case, it will download images for the following combinations:

• “West” region, “Furniture” category

• “East” region, “Technology” category

• “Central” region, “Office Supplies” category

You can customize the filter_df dataframe to include more combinations of region and category filters as needed.
