Therefore, you can use a while loop instead of a do-while loop, if you ensure that the loop statement is run at least once by setting the condition to be true before the loop e.g., with a temporaray variable and an or-connective or as in Dwin's answer. – Henrik Dec 6 '10 at 11:53.

break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop. next halts the processing of the current iteration and advances the looping index.

R - While Loop - The While loop executes the same code again and again until a stop condition is met.
Can this be used for warnings messages too? For example, if I get a warning that says a model did not converge, can I use this to skip the models producing this warning in the for-loop? Here is an example of Stop the while loop: break: There are some very rare situations in which severe speeding is necessary: what if a hurricane is approaching and you have to get away as quickly as possible? You don't want the driver's assistant sending you speeding notifications in that scenario, right? This seems like a great opportunity to.
