ggforce | Accelerating ggplot2 | Data Visualization library

I study extinctions of species (=y) across decades of the 19th century (=x). I am plotting a smoothed spline, which shows a cumulative value of extinct species, across a set of several bars which show the absolute value per decade. Now, the smoothed spline ends at the center of the last bar as the value occurs at the center of the X-postion. As this is visually unpleasant, I would like to extend the spline so that it continues to border of the plot.

I tried the position argument but dodge does not help. The geom_bspline function does not seem to offer a solution either (e.g. type="open" does not help).

So I am looking for a solution that allows to extend the geom_bspline from the ggforce package (or a similar solution).

Below I added the plot and the code example for the plot.

I have several data frames that I want to plot on the same graph. However, I would like to circle or enclose points (something similar to ggforce::geom_mark_ellipse() but any solution will do) that have the same row index. For example, if I have some data and make a plot like below:

I am looking at biological data of guinea pig with 2 treatment groups (hifat or no hifat diet) and when I facet_wrap the boxplots and add the stat_compare_means (t.test) function, the p-value is cut off. When I remove the scales="free", it still cuts off the p-value. I used the function to move the wording but since all graphs have different scales a fixed value for instance at y=1 would force all the axes to be the same. Would love any guidance.

For the follow data df and plot, I hope to smooth the line, especially for the sharp corners parts marked by the blue rectangles in the figure below:

I have the following example:

Problem:

I have a large amount of data I am trying visualize for my users. This may be several hundred plots. In the app currently I am making ggplot2 small multiples using facet_wrap and that's working pretty well up to around 100 plots. However, I want the user to be able to export all of the plots as a record of what they have done and also to be able to visualize all of the plots, not just the first 100. I'm not too worried how it's formatted (ie as a ggforce::facet_wrap_paginate() or as completely separate plots as below).

I have tried several approaches I found on stack-overflow but nothing seems to be working

The following code works if I try and export the plots in R but I can't get the download in shiny to work.

I want to create a hexagon that surrounds the plot created from the following code:

How can I modify the multiplot function to fit graphs that use coord_fixed() without white space between columns in Shiny plotOutput?

This is a small reproducible shiny app with the problem:

I'm trying to format my datatable output. I want to make some changes to the table format (e.g, hide the row names) and hide columns (e.g., hide gears and carb, which I use to filter the datatable). I've read through this response before, but can't seem to get it to work. Does anyone have any suggestions for me?

I've prepared reproducible code below. In a nutshell, I'm using the mtcars dataset (my actual dataset is longer). Users can set filters, and the table output will update accordingly. It's this part of the code (under server) that isn't working:
