Package reprex not available for R version 3.3.3

[ALEXX_TheCurator]

I’m a beginner battling a C problem and was advised to use R to create a MWE. Downloaded, and installed the latest version but my macOs doesn’t support. Downloaded a version older but can’t install the reprex package like the tutorial says to. I’ve also tried to update the R software from from tool bar but that’s unresponsive.

reprex will work on R 3.4 or greater. If you are on Big Sur or higher, you should be able to install the current version, R 4.2.1—Innocent & Trusting. However, there are two versions, one for Silicon chips and one for Intel.

For an MWE illustrating a problem in C, reprex isn't necessary and would not be simple to produce. Here's an example, mwe.c illustrating what's generally expected—a cut-and-paste-able copy of as much of the source code needed so as to fail in the same way:

/* add.c
 * a simple C program source: http://www.cs.toronto.edu/~heap/270F02/node9.html
 */ 
#include <stdio.h>
  
int main()
{
    int i, sum = 0;
   
    for ( i = 1; i <= LAST; i++ ) {
      sum += i;
    } /*-for-*/
    printf("sum = %d\n", sum);

    return 0;
}

This lacks #define LAST 10 and produces an error on attempted compilation

➜ gcc mwe.c
