Volcano plot

[rfarouni]

The Volcano plot takes a very long time to render

I don't know how I would fix it? It takes no time in the R-package in my experience? This is R-shiny specific?

I am not sure. I keep getting this progress bar. Do you know what function prints it? |=========================== | 25% ~7 s remaining

After dozens of experiments and modifications, I am still not unable to get it to display. Whatever the problem is, it is most probably not connected to

• other elements in the display
• the grid form of the output
• highcharts

I have a lurking suspicion that it is caused by shinyFiles and this warning in particular Found more than one class "connection" in cache; using the first, from namespace 'BiocGenerics' One thing we can do is plot some fake data in the volcano plot and see what happens Another thing we can do is disable shinyFiles.

I have added a temporary scatter plot function that is similar to the volcano plot but uses a small dataset that is read inside the function from a character object. The plots renders without a problem in the Shiny app. We need to try to read the entire data with the peaks inside the function to rule out data size or format.

This works on my mac, is it still a problem in linux?

Data trimming seems to work for now
