Background: I have an R Shiny web app that allows a user to input a file in any arbitrary format (e.g., .csv, .tsv), but after read in the file exists on the R server as an R dataframe. I'd like to make use of google visuals without relying on the R package for google visualization and simply use my own HTML and javascript to interact with google charts.
Question: I'm trying to learn how to convert my R dataframe to a datable table that can subsequently be passed to the google charting functions. Something as in here is R code to create a simple dataframe. > tmp <- data.frame(v1 = rep(1:4), v2 = rnorm(4)) > tmp v1 v2 1 1 -1.9372140 2 2 -1.5234370 3 3 0.2374601 4 4 1.0550744 Now supposing this is sitting on the R server, I *think* it would be represented as a datatable such as: var data = google.visualization.arrayToDataTable([ ['v1', 'v2'], ['1', -1.9372140], ['2', -1.5234370], ['3', 0.2374601], ['4', 1.0550744] ]); If so, I could then use various google charts for visual display of these data. The resources I'm reviewing include this one below, but if anyone has support or worked examples I would be grateful. https://developers.google.com/chart/interactive/docs/queries -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
