iri | IOTA Reference Implementation | Blockchain library

I need create an empty loop that runs for a given time, for example 2 hours. The loop just runs for nothing, no matter what it does, it is important that it loads R executions for exactly 2 hours.

for example, let's have some kind of script

Is there a way to add an icon to column headers by renaming it . I tried with below

Consider this famous table (already exists in R)

This is a bit harder to explain than my last question because the problem is not exactly reproducible.

I am producing legends for a couple of maps and am drawing a box around both legends since one has only 1 item (a line feature) and the others are discrete fills (a polygon feature). Using geom_sf to plot both.

I end up with a weird artefact that looks like part of the lines are drawn twice with just a slightly shifted position.

I managed to produce a similar error with the iris dataset where legend.box.background is only partially drawn.

In a R Notebook there is a function that makes many plots and print summary statistics in the console. I would like to get the plot and the console output (i.e. summary statistics) side by side on the HTML output.

Here is a very simple example:

I am trying to run RSK blockchain node RSKj on a Windows machine. When I run this line in a terminal:

I am making an app which can generate plots from input and it has no problem showing it on the UI but when I try to zip it by putting them into a temporary directory using ggsave() and use zip(), it doesn't work.

The example I have here generated the plot file in the temporary directory, but no zip file was generated. There is an extra directory in the temp dir which makes me think it has tried the process but somehow stopped.

Here is my code:

I am using SDL2 for the first time, and when I try to create a window, it's not displaying. The only sight of the window is an icon spawning in my dock (Image of the icon, SDLTest.out is the name of my executable file). I found out that it spawned when SDL_INIT()was called.

I tried updating the window, changing its color and adding the flag SDL_WINDOW_SHOWN, but none of these solutions worked. I even pasted a code from the Internet, but it didn't work better.

Here is the code that I pasted:

There are a number of different Q/A's regarding this topic on SO, but none that I have been able to find that fit my use-case. I am also very surprised that RStudio / the Shiny developers themselves have not come out with some documentation on how to do this. Regardless, take this example application:
