we need to make it a local variable (simply re-assigning it will do the trick), with the use oflocalwrapping theforblock, with the formfor (i in 1:4) local({i = i; … rest of the loop … })and use the operator<<-to assign the plots to the list inside the ...

Programming languages typically have a way to allow the execution of a single line of code or several lines of code multiple times, or in a “loop”. While “loops” are possible in R, there are functions that more directly achieve this purpose, such as theapply()family of functions and...
To find a solution, I initialized the pdf file within the for loop and added an if clause to check if the first iteration was running. If the current iteration was the first one, I created the output device using pdf(). After closing the for loop, I added dev.off (). Here's a ...
