How do I assign a variable label in SAS?

How do I assign a variable label in SAS?

The first method to assign a label to a variable in SAS is with a DATA Step. To create a variable label in a SAS DATA Step you need the LABEL keyword, followed by the variable name to which you want to assign a label, an equal sign, and the desired label between single quotes.

What is label in variable view?

The name and the label of your variables in SPSS Statistics serve the same basic purpose: They’re descriptors that identify the variable. The difference is that the name is the short identifier and the label is the long one. However, output looks better if you use short names and somewhat longer labels.

What is a variable label in Stata?

Stata allows you to label your data file (data label), to label the variables within your data file (variable labels), and to label the values for your variables (value labels). Let’s use a file called autolab that does not have any labels.

How do I assign a variable in SAS?

Ways to Create Variables

1. Overview.
2. Create a New Variable Using the LENGTH Statement.
3. Create a New Variable Using the ATTRIB Statement.
4. Create a New Variable Using an Assignment Statement.
5. Reading Data with the INPUT Statement in a DATA Step.
6. Create a New Variable Using the FORMAT or INFORMAT Statements.

What is the purpose of a label statement in a data step?

We use the label statement in the data step to assign labels to the variables. You could also assign labels to variables in proc steps, but then the labels only exist for that step. When labels are assigned in the data step they are available for all procedures that use that data set.

What is variable label?

Variable label is human readable description of the variable. R supports rather long variable names and these names can contain even spaces and punctuation but short variables names make coding easier. Variable label can give a nice, long description of variable.

What is the difference between variable name and variable label?

The variable name is a short and less detailed variable. These variables are placed in the graphs and output tables. The variable labels contain detailed information and they are composed of a set of words that shows how a variable looks like.

What is a label variable?

Variable Labels: Variable labels are composed of a few words that describe what a variable represents. If the variable labels are properly formatted in SPSS, they will show in output tables and graphs, instead of variable names.

Can you assign labels to variables in PROC steps?

You could also assign labels to variables in proc steps, but then the labels only exist for that step. When labels are assigned in the data step they are available for all procedures that use that data set.

How to assign the same label to multiple values?

If a numeric variable represents ordinal codes (or has some discernable order), you can assign the same label to multiple codes in a range. Format LIKERT7_B assigns the label “Disagree” to values 1 through 3, and assigns the label “Agree” to values 5 through 7.

How to assign labels to a data frame?

You can assign the labels using lapply: label (data) = lapply (names (data), function (x) var.labels [match (x, names (var.labels))]) lapply applies a function to each element of a list or vector.

When to use variable labels and Value labels?

When assigning value labels, a “variable TO variable” format can be used ( see above ), instead of listing each variable name separately, as long as the variables are in consecutive order in the dataset (and you want to assign the same labels to all of those variables).
