In the “New Value:” box on the top right, give this range a value of 1. Recoding several variables into several new variables is straightforward: simply fill in multiple input variable names after RECODE and multiple output variable names after INTO. This is what the Recode into Different Variables: Old and New Values dialog box should look like when you are done: Click on the Continue button to return to the Recode into Different Variables dialog box.

However, once you understand it you will find it saves you a lot of time and pain. same variable, using the recode statement instead so that you can see that the recode statement requires a lot less coding and only two steps. We will illustrate this with the hsb2 data file with a variable … You will get this syntax read out that tells you what you just did. Then click on the button (see Figure 18). Almost every SAS programmer has written a DATA step that uses IF-THEN/ELSE logic or the SELECT-WHEN statements to recode variables.Although creating a new variable is effective, it is also inefficient because you have to create a new data set that contains the new variable. Figure 18 You would do this by dragging the variable from the Data Sets tree onto a page, as shown below. recode s1 to s4 (else = copy) into c1 to c4. This is allowed if you recode one variable and you do not plan to define value labels Then put them all back into the same dataframe – Bertrand Feb 7 '18 at 22:38 ...

Bulgarian / Български You can merge columns, by adding new variables; or you can merge rows, by adding observations. In this example, we will illustrate various aspects of how the program works by recoding age into a new variable with four categories. This is not how Displayr works.

In the “Recode into Different Variables: Old and New Values” dialog box, select “Range:” and enter 15 in the first box and 24 in the text box below. The easiest way is to use revalue() or mapvalues() from the plyr package. 3 Using Recode to make a quantitative variable into a set of ordered categories From the Date, Syntax or Output windows… Transform Recode Into Different Variables • recode statements can be used to create new “versions” of variables • the new variable will “appear” in the rightmost column in the data set alter type s1 to s3 (f1) s4 (f6.3). For example, you might want to use fewer, more aggregated categories than those used in collecting the data, change the ordering of a variable’s categories for some reason, or recode a quantitative variable as a categorical variable. In the Output Variable box, type in a name for the new (grouped) variable. *For each variable, flag conversion failures: cases where converted value is system missing but original value is not empty. If percentages appear, as shown below, you need to click on the variable in the Data Sets tree and change the structure (Properties > INPUTS  > Structure, on the right of the screen) to Numeric.

Click Old and New Values and specify how to recode values. By commenting, you are accepting the In the recoding scheme, we need to specify how the values of old variables are converted into the values of new variables. If percentages appear, as shown below, you need to We still do not have labels attached to the values of the new variable. Portuguese/Portugal / Português/Portugal (The only time you'd use that is when fixing fouled labels.) Bosnian / Bosanski Click on OK to perform the recode.

German / Deutsch On the right side of the window, under Output Variable, type a name for the new variable, and optionally a variable label. In the following sections, we will discuss: How date-time variables work in SPSS. The merging and the values are completely independent (when you merge it does not affect the values and recoding the values has no impact on the merging of categories). Standard formats for dates and time. You will now see the “Recode into Different Variables” window. Italian / Italiano Similarly, we might code the dichotomous variable for sex: 0 = Female 1 = Male Dichotomous variables can also be dummy variables.

Greek / Ελληνικά The left side of equal signs (=) is for the values of old variables, and the right side for the values of new variables. To add columns use the function merge() which requires that datasets you will merge to have you can you use this variable for further analysis after dichotoming or making an order scale as you like. The Recode into Different Variables window will appear. The above examples illustrate how to recode variables into the same variables. So, IPP should be a new variable including initial variables 1-4 and the INPP should be a second new variable including initial variables … 3 Using Recode to make a quantitative variable into a set of ordered categories From the Date, Syntax or Output windows… Transform Recode Into Different Variables • recode statements can be used to create new “versions” of variables • the new variable will “appear” in the rightmost column in the data set On the Variables and Questions tab, select multiple variables at the same time and recode them together.

Example 2: Recoding continuous variables into categories. *Convert variables to numeric. Setting the century range for two-digit years. Then, we use recode to convert mpg3a into three categories: min-18 into 1, 19-23 into 2, and 24-max into 3. Let's say you wanted to compute the average age. If you want to recode variables into different variables, add an into command, with your new variables' names at the end: Brandon Bertelsen, I have only ever heard "recoding" used in the usual sense "rename categorical labels/ reorder categorical levels/ swap levels <-> labels".Never for "convert continuous variables into discrete categories", which is binning, not recoding.Nor for changing cut thresholds or quantiles. 4recode— Recode categorical variables.

For example, you might want to use fewer, more aggregated categories than those used in collecting the data, change the ordering of a variable’s categories for some reason, or recode a quantitative variable as a categorical variable. To use recode, you must provide a list of variables to be recoded and the rules associated with that change.. For a variable (for example, q1) that contains integers ranging from 1 to 7, to collapse the values into three categories, use: recode q1 1=1 2=1 3/5=2 6=3 7=3 This will code M as 1 and F as 2, and put it in a new column.Note that these functions preserves the type: if the input is a factor, the output will be a factor; and if the input is a character vector, the output will be a character vector. Search You can use recoding to produce different values or codes for a variable. Recoding into the same variables works in the same way as recoding into different variables except there’s one important distinguishing characteristic.
