"Satisfactory" for those with a gpa greater than or equal to 2.5."Good" for those with a gpa greater than or equal to 3.0 and."Excellent Grades" for those with a gpa greater than or equal to 3.5,.Suppose we want to create a variable called gpagroup which takes on one of 3 values:
ROBOTC IF ELSE CODE
SAS code follows the rules of logic: SAS evaluates if-then statements in the order in which they appear in the datastep. The value "Good standing" is not the same as the value "good standing". The exception is in the value of character variables. Note that SAS does not generally distinguish between upper and lower case (you can use either). If gpa= 3.0 then group = "good standing" The new variable called group takes on one of two values: "good standing" if a person's gpa is greater than or equal to 3.0 and "not good standing" if a person's gpa is less than 3.0. The following code creates a new variable called group from an existing variable called gpa. SAS will keep evaluating the if-then-else-if statements until it encounters the first true statement.Ĭharacter variable data must always be enclosed in quotes. Note that this if-then-else-if statement could equivalently be writtenĪn if statement can be followed by exactly one else statement or by many else-if statements.
A person whose age is 40 or younger will not be assigned to an agegroup, and their agegroup variable will be missing. A person whose age is greater than 60 will be in agegroup 3. A person aged between 50 and 60 will be in agegroup 2 (again, notice the strict inequality: those aged exactly 50 will not be included in this agegroup, but will be in agegroup 1). A person whose age is between 40 and 50 (notice the strict inequality: those aged exactly 40 will not be included) will be in agegroup 1. else-if statements are useful when forming mutually exclusive groups. SAS evaluates the expression in the else-if statement only when the previous expression is false. Note that the above statement could equivalently be writtenĪn optional else statement can be included (if-then-else) to provide an alternative action when the if expression is false.įor a person whose age is less than 65, the variable older will equal 0.Īn optional else-if statement can follow the if-then statement. For a person whose age is less than 65, the variable older will be missing. When the expression is false, SAS ignores the statement following then. When the expression is true, the statement following then is executed. is an open platform for users to share their favorite wallpapers, By downloading this wallpaper, you agree to our Terms Of Use and Privacy Policy.Creating New Variables Using if-then if-then-else and if-then-else-then StatementsĪn if-then statement can be used to create a new variable for a selected subset of the observations.įor each observation in the data set, SAS evaluates the expression following the if. please portion this image for your beloved friends, families, action via your social media such as facebook, google plus, twitter, pinterest, or any new bookmarking sites.
