R within a downloadHandler object, and I'd like to avoid that. Is there any way to output the page as a pdf more easily. More specifically, is there any way to directly reference the output tables and plots i. Edit: Here is some simplified code. Note getDataset is a reactive function that queries a database based on the inputs.
My goal is to simply add an "Export" button that exports the already-generated plots and table. Also as a side note, is there any way I can get a reactive dataset that is shared among all reactive elements? First of all , you should really produce a reproducible example not just a sample of your code. We should copy and paste your code and it will run. Using grid. Then, downloadhandler will do the download.
To not regenerate all the plots each time, I think one solution is to save them in a global variable that you update each time you change the plot. Here reactiveValues come in rescue to store plots and tables ad dynamic variable. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. Again, the UI is straightforward: use either downloadButton id or downloadLink id to give the user something to click to download a file.
The results are shown in Figure 9. You can customise their appearance using the same class and icon arguments as for actionButtons , as described in Section 2. Unlike other outputs, downloadButton is not paired with a render function. Instead, you use downloadHandler , which looks something like this:. The job of this function is to create the name that will be shown to the user in the download dialog box.
The job of this function is to save the file in a place that Shiny knows about, so it can then send it to the user. This is an unusual interface, but it allows Shiny to control where the file should be saved so it can be placed in a secure location while you still control the contents of that file. The following app shows off the basics of data download by allowing you to download any dataset in the datasets package as a tab separated file, Figure 9.
I recommend using. You can avoid this complexity by using tab separated files, which work the same way everywhere. Note the use of validate to only allow the user to download datasets that are data frames.
A better approach would be to pre-filter the list, but this lets you see another application of validate. As well as downloading data, you may want the users of your app to download a report that summarises the result of interactive exploration in the Shiny app.
