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/"
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.
