![]() IF some condition is meet, THEN, you run some code, ELSE, you run other code. Hence, the condition must return TRUE if the condition is meet or FALSE if not. Typically the actions are compound statements. You need to define one or more conditions you would like to meet to run some code, and otherwise, run other code. Creating markdown and R scripts in RStudioīio: Jeffrey M Li is a Data Scientist at Dataquest. If condition is TRUE, trueaction is evaluated if condition is FALSE, the optional falseaction is evaluated.Using string/date manipulation to write functions In R, an if-else statement tells the program to run one block of code if the conditional statement is TRUE, and a different block of code if it is FALSE.Extracting years, months, days from a date object.Concatenate, extract characters in a string.How to manipulate strings and dates by writing your own headline generator.An simple method of iterating over multiple values.Writing functions with control structures.How to build your own soccer match prediction function:.Building upon the concepts in this tutorial, you'll learn: If you'd like to learn more, this tutorial is based on our R Intermediate course, which is part of our Data Analyst in R track. ![]() The if-else conditional will go between the brackets of the while loop. In our previous example, where 15 wins allowed us to make the playoffs, let's add an if-else conditional. Adding an if-else statement into our while loop is the same as adding it to our for loop. To do this, we'll need to add an if-else statement into our while loop. Now that we've printed the status of the team when they don't have enough wins, we'll add a feature tthat indicates when they do make the playoffs. Using an if-else statement within a while loop Let's write our first while loop, counting red dragon wins! Notice, that we continuously add 1 to the win total, so eventually, the win < 10 condition will return FALSE. Our loop will stop running when wins hits 10. If we were to write a loop for the following code:
