I am in the process of developing interactive reports with Rmd files, which specify a shiny runtime. I have, however, run into the following issue.

When plotlyfying ggplots that have larger height specifications, they start overlaying other aspects of the html output (e.g. in the exaple here its the text). So far my research has yielded that a fixed setting of height == 400px in the poltly container is responsible for this.

---
runtime: shiny
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE, warning = FALSE, message = FALSE)

library(tidyverse)
library(shiny)
library(plotly) 
```

```{r}
fluidRow(
  column(3,
         selectInput("myselectorID",
                     "Select:",
                     selected = "setosa",
                     choices = c("setosa", "versicolor", "virginica")))
)

renderPlotly({
  data <- iris %>% filter(Species == input[["myselectorID"]])
  ggp <- data %>% ggplot(aes(x = Sepal.Length, y = Sepal.Width))  
    geom_point()
  ggplotly(ggp, height = 487)
})
```
START
TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT
TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT 
TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT
TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT

TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT
TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT
TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT TEXT
END

If I supply the following css (e.g. via the yaml header) then the problem is supposedly solved:

.plotly {
  height: 100% !important;
}

I would prefer a solution where I pass the parameter to R functions though. Any ideas? Thank you!

Someone answered this and deleted their answer which was working... Not sure why but here's what they posted for the record since it seemed to do the trick:

                     choices = c("setosa", "versicolor", "virginica")))
)

# create a specific plotly output with the parameter set as desired
plotlyOutput("testplot", height = "100%")

# address the plotly output
output$testplot <- renderPlotly({
  data <- iris %>% filter(Species == input[["myselectorID"]])
  ggp <- data %>% ggplot(aes(x = Sepal.Length, y = Sepal.Width))  
    geom_point()
  ggplotly(ggp, height = 487)

To expand on this solution, you can programmatically insert ggplotly outputs of specified heights like this:

1. set one ore more ids at which to place the plot output with insertUI later:

uiOutput('some_plots')

2. render the output and insert it at the specified output id; specify plot height as an argument to plotlyOutput():

Example (inserting three ggplotly outputs of different heights at id "some_plots"):

plot_heights = c(200, 150, 350)

for(plot_index in 1:3){
  plot_name = paste0('plot_', plot_index)
  my_plot <- qplot(data = iris,
                   x = Sepal.Length, y = Sepal.Width,
                   geom = 'point') %>% ggplotly()

  output[[plot_name]] <- renderPlotly(my_plot) ## add to output list
  
  insertUI(selector = "#some_plots",
           where = "afterEnd",
           ui = plotlyOutput(plot_name,
                             ## specify plot height:
                             height = paste0(plot_heights[plot_index],'px')
                             )
  )
}
