Oto trzy najpopularniejsze sposoby dzielenia zbioru danych w SAS-ie:<\/span><\/span><\/p>\n

Metoda 1: Wybierz, kt\u00f3re kolumny zachowa\u0107<\/strong><\/span><\/p>\n

 data<\/span> new_data;\n    set<\/span> original_data;\n    keep<\/span> var1 var3;\nrun<\/span> ;\n<\/strong><\/span><\/pre>\n
 Metoda 2: Wybierz, kt\u00f3re kolumny chcesz usun\u0105\u0107<\/strong><\/span><\/p>\n
 data<\/span> new_data;\n    <\/span>set<\/span> original_data;\n    <\/span>dropvar4<\/span> ;\n<\/span>run<\/span> ;<\/span><\/strong><\/span><\/pre>\n
 Metoda 3: Wybierz wiersze, kt\u00f3re chcesz zachowa\u0107, w zale\u017cno\u015bci od warunku<\/strong><\/span><\/p>\n
 data<\/span> new_data;\n    set<\/span> original_data;\n    if<\/span> var1 < 25<\/span> then<\/span> delete;\nrun<\/span> ;<\/strong><\/span><\/pre>\n
