The For Loop. The for loop is used when you know in advance how many times the script should run. Explanation: The example below defines a loop that starts with i=0. The loop will continue to run as long as i is less than, or equal to 10. i will increase by 1 each time the loop runs. Note: The increment parameter could also be negative, and the <= could be any comparing statement. How to use the for loop to loop through the different HTML headers.
If you are writing a for-loop inside of a larger construct, the number of times you want to loop could depend on the length of a vector which could change depending on other factors. Therefore, you can set up your counter in vector part of the loop like this.for (i in 1:length(foo)) { #stuff to do the number of times that foo is long }. The well constructed loop. If you are running into speed problems there are a couple of things to try (see also the R inferno). little background: 1) Loops are slow in R. This fact puts lots of R users on the defense from the very beginning. Users of almost any other language can just bring up looping speed when they want to get under R usersâ skins. The fact is, for many people, it doesnât matter.
