R+Shiny: read file and use its content

Asked 2022-Mar-10 at 14:31

Please find below an example of a script I found online (probably from Rstudio) to create a simple app to read a variety of flat files and output a table. I added a bit which creates the file "test_input_file.csv" which the app can read.

I am lost with a very simple task: after reading the csv file, I have a tibble and I render it as a table. How do I access this tibble directly to do something else with it? E.g. plot it with plotly, take some statistics etc...? Many thanks

This code loads the file straight into the output table and doesn't really store the raw table anywhere. This snippet of code is actually loading the file:

You shouldn't assign the output of tab_model() to a variable - that prevents it from writing the HTML file. If you just run tab_model() without assigning it to test you'll be fine.

The following works for me:

cannot remove grey background from PNG produced via ggsave()

Asked 2021-Nov-18 at 23:10

I've been trying to save a flextable as a ggplot, then write it to a PNG for gridding. I've gotten what I need, except that the background of the resulting PNG is grey, like this:

Whereas the plot view of the ggplot looks like I want it to (but low res):

The issue is that when you plot an empty plot, the default panel background is light gray. That's what you're seeing, so you need to set the panel background to blank (or transparent), then it should work. Here's an example with a simple rectGrob from grid to give you the idea:

gt summary rows - position label in existing column

Asked 2021-Oct-29 at 17:05

I have created a gt table and I want to have a row at the bottom of the table with the sum of all the columns. I want to position this so that the row label "total" sits within an existing column (the column catchment in my example) rather than out to the side. How do I do this?

...

ANSWER

Answered 2021-Oct-29 at 17:05

Option 1: Move your "Catchment"/Lake_labels column into `gt(rowname_col = "Lake_labels"), this moves them into the "stub" and aligns with the summary calculations.

Option 2: Pre-calculate the summary rows ahead of time. This means you can treat the summary row as another other cell value.

R + shiny + plotly: ggplotly moves the legend to the right

Asked 2021-Sep-23 at 20:19

Please have a look at the reprex at the end of the post. Essentially, I create a very simple ggplot2 visualization inside shiny. When I call ggplotly on it in order to get a plotly interactive visualization, the plot legend which was at the top of the plot, gets shifted to the right. Any idea about how to fix that?

Many thanks!

We can add some plotly grammar to fix it.

R + Shiny + conditionalPanel: combining condition on UI and server side

Asked 2021-Sep-22 at 10:05

I am struggling to get this done: I want to display a button in the sidebar of a shiny application (called "download aggregated data") if and only if two conditions are met, namely

(1) I select the "yes" value from the menu under "Show extra button" and

(2) The data selected and shown in the table has at least 20 rows.

Condition (2) is the consequence of selecting "large_chunk" in the "select data chunk" menu, but I want the condition to be based on the output and not on the input. In the real-life app which I am developing I will not know beforehand how many data rows I will select with my filters.

Right now only condition (1) is implemented.

I found something useful here about conditionalPanel and a condition on the server side

Shiny - conditionalPanel - set condition as output from server

but I did not get very far. Any help is appreciated!
