(I recommend assigning the results of an if statement only when the entire expression fits on one line; otherwise it tends to be hard to read.) The general syntax for IF function with multiple conditions is =IF (condition one is true, do something, IF (condition two is true, do something, IF (conditions three is true, do something, else do something))) The ifelse() statement is a vectorized version of the if() statement. The block IF statement evaluates a logical expression and, if the logical expression is true, it executes a set of statements called the IF block. If the condition is not met, then it returns FALSE, and the block of code will not run. Conditional statements include if(), the combination if()/esle(), ifelse(), and switch(). and comparison = for this to work normally both conditions provided with should be true. Suppose, you have a table with the results of two exam scores. Here we are going to take the same data set.
