gganimate | A Grammar of Animated Graphics | Data Visualization library

I am creating an animation with gganimate but I need to show the date on title. My data df (dput() included at the end) is small and the animation works fine when I do not show the title with date but I need to include it. Here is the code I used:

I have a plot with several hundred lines. I would like these lines to appear over time; first slowly, to have the time to explain what's going on to the audience; then faster and faster.

The minimal example below gives an example of how the animation currently looks. What I want is that the first frame has a few seconds, the second is roughly half as long, the third another half of that, etc. Essentially, the duration should get exponentially smaller.

However, I cannot figure out how to change the duration. I thought that the option ease_aes() should do it as it allows functions such as exponential_in. Using this option though seems to change nothing for me.

I also found an SO post that slows one particular frame down, so I thought I should be able to apply this code to my use case. Again though, the transition duration looks identical across frames. (Note that the last example has the issue that the prior line disappears, which is also not want I want; it's just to illustrate though that the durations don't change).

What am I missing?

I'm trying to create an animation where an object is drawn whilst gradually changing its colour. For illustrative purposes assume that the object I want to draw is a circle.

What I have so far

I create a dataset that contains the coordinates of my circle, a time variable and a alpha variable for gradually changing the colour:

I want to make a plot animate. I need that the points appear and disappear, but only make that the movements of points.

I'm currently following this tutorial to learn to create animated plots using the gganimate library.

However I'm already struggling with the first animation. While the animation itself works, its resolution is downscaled as compared to the example on the website. Resizing the 'Viewer' in RStudio does not change the dimensions/resolution. Plotting the image without animation (plot(p)) creates a plot in 'Plots' that has the same dimensions and resolution as the one from the website. Do I need to adjust some settings for the Viewer? I'm working on Windows 10, RStudio Version 1.4.1717, R Version 4.1.1.

The animation from my viewer:

I have been trying to implement ''the Visualisation of the 2014 Ebola outbreak in Sierra Leone'' using ggplot2 and gganimate as described in the Article available at https://aberdeenstudygroup.github.io/studyGroup/lessons/Visualising%20Spatial%20Data/Visualising_Spatial_Data_in_R/ using the shp files available at https://data.humdata.org/dataset/a4816317-a913-4619-b1e9-d89e21c056b4 and the dataset available at https://github.com/AberdeenStudyGroup/SG-T14_ggmap_gganimate/blob/master/SG-T14-data/ebola.csv (just for simplicity to follow).

My challenge is in the second plot (ebola_plot_sub) which is obtained by combining the ebola dataset and the shp information by using the below codes as described in the article. The plot I'm getting has a lot of lines crossing each other different from what is presented in the original writing, (ie. totally distorting country map margins).

(Note: the animation part for the entire dataset is a bit tricky because of the changes in the package but can forget about it for know).

I am trying to make a ggplot with facet_wrap and for some reason some subplots don't display and appear blank some of the time.

I'm using RStudio with the {gganimate} package in a restricted research environment (a Windows 10 VM with several modifications) to create animated graphs in .gif and .mp4 formats - when they are rendered within RStudio they display fine, but if I save the files using anim_save() I can't open the resulting files in either the provided Windows Image Viewer or web browser (or the media player in case of .mp4) - it always says the file is broken or cannot be displayed.

There is a lengthy process involved in exporting these files out of the restricted environment, so I'd like to check if they are actually broken, or just cannot be displayed in this particular OS for whatever reason. Can RStudio open/display .gif files or videos? Note: I know how to display an animation using print()/plot() methods - this is about opening/displaying an external animated file after it's been exported.

Example code to generate animated plot and save as .gif/.mp4 below:

I'm trying to show the growth of COVID cases in New York state

This code gets the plot I want but without the animation or aspect of time.
