googleVis | Interface between R and the Google Chart Tools | Data Visualization library

I am working on a Shiny app that includes an interactive Sankey diagram. My quandary is this: I prefer the aesthetics of the plots generated with the ggalluvial package (especially the ability to easily color links by some factor), but it does not natively support tooltips where the user can see details about the link or node when they click or hover on it (as in networkd3 or googleVis Sankey diagrams). Plotly does not support geom_alluvium and geom_stratum, so ggplotly() does not appear to be an option in this case.

I have essentially no JavaScript experience, so I apologize if this question is too vague and open-ended. I would like to know what is necessary to enable tooltips on ggalluvial plots in Shiny.

To be more specific, here is some example code for a shiny app with a basic Sankey diagram in it. My desired behavior would be to enable a tooltip to appear when the user hovers (or alternatively clicks) on a link between two nodes that gives some information about the IDs of the flows. For example in the screenshot below, I would like a box with 1,3 in it to appear when the user hovers over the area in upper left indicated with the arrow, and 7,9 when they hover over the arrow in lower left. Those are the values in the ID column that correspond to the flows they are hovering over.

Any guidance on how to do this?

Arrows indicate examples of where tooltips should appear.

I am trying to create an interactive shiny app that shows the user a Plotly map and allows the user to select different counties in the U.S. Then it can use the info on the selected counties to generate a GoogleVis motion chart. I have successfully constructed the program locally, and here is the ui and server function:

I am trying to create an interactive shiny app that shows the user a Plotly map and allows the user to select different counties in the U.S. Then it can use the info on the selected counties to generate graphs and plots. However, it seems that the choropleth map only returns the curveNumber, pointNumber, and z value upon selection. How can I identify the selected county from this info? Or how can I make it gives the county names upon selection? Here is my ui and server function:

I am trying to create an interactive map using Plotly in the Shiny app that allows the user to select the region by box select and lasso select on the map, then it can return a GoogleVis motion chart showing the statistics on the region selected within the Shiny app. However when it comes to the output function of GoogleVis:

I have build a shiny application which works completely fine when I am running it through RStudio. But when I am trying to publish my R application through Shiny it is getting as error. This is the message below:

R Gurus,

I need your help to determine multiple overlapping timelines in R using tidyverse/dplyr.

Here is the dataset:

I am trying to build interactive multi-level sankey diagram using R. I can't find the solution how to assign the levels to nodes. For example, a1 node should be on the second level in chart but not in the fifth. It seems that the package assigns to the last node in the chain the rightmost position, which is not preferable in my case.

I tried different packages like echarts4r, networkD3, ggvis but it seems that these packages doesn't provide the functionality to manage levels in graph.

If you know how to solve this issue, please, share.
