Istniej\u0105 trzy popularne sposoby dodawania nowej kolumny do ramki danych w R:<\/span><\/p>\n

1. U\u017cyj operatora $<\/strong><\/span><\/p>\n

 df$new <- c(3, 3, 6, 7, 8, 12)\n<\/strong><\/span><\/pre>\n
 2. U\u017cyj podp\u00f3r<\/strong><\/span><\/p>\n
 df[' new<\/span> '] <- c(3, 3, 6, 7, 8, 12)<\/strong><\/span><\/pre>\n
 3. U\u017cyj Cbind<\/strong><\/span><\/p>\n
 df_new <- cbind<\/span> (df, new)<\/strong><\/span><\/pre>\n
 W tym samouczku przedstawiono przyk\u0142ady praktycznego wykorzystania ka\u017cdej z tych metod przy u\u017cyciu nast\u0119puj\u0105cej ramki danych:<\/span><\/p>\n
 #create data frame<\/span>\ndf <- data. frame<\/span> (a = c('A', 'B', 'C', 'D', 'E'),\n                 b = c(45, 56, 54, 57, 59))\n\n#view data frame\n<\/span>df\n\n  ab\n1 to 45\n2 B 56\n3 C 54\n4 D 57\n5 E 59<\/strong><\/span><\/pre>\n
 Przyk\u0142ad 1: u\u017cycie operatora $<\/strong><\/span><\/h3>\n
 Poni\u017cszy kod pokazuje, jak doda\u0107 kolumn\u0119 do ramki danych za pomoc\u0105 operatora $:<\/span><\/p>\n
 #define new column to add\nnew <- c(3, 3, 6, 7, 8)\n<\/span>\n#add column called 'new'\ndf$new <- new\n<\/span>\n#view new data frame\ndf<\/span> \n\nab new\n1 to 45 3\n2 B 56 3\n3 C 54 6\n4 D 57 7\n5 E 59 8\n<\/span><\/span><\/strong><\/span><\/pre>\n
 Przyk\u0142ad 2: U\u017cywanie nawias\u00f3w<\/strong><\/span><\/h3>\n
 Poni\u017cszy kod pokazuje, jak doda\u0107 kolumn\u0119 do ramki danych za pomoc\u0105 nawias\u00f3w:<\/span><\/p>\n
 #define new column to add\nnew <- c(3, 3, 6, 7, 8)\n<\/span>\n#add column called 'new'\ndf[' new<\/span> '] <- new\n<\/span>\n#view new data frame\ndf \n\n  ab new\n1 to 45 3\n2 B 56 3\n3 C 54 6\n4 D 57 7\n5 E 59 8\n<\/span><\/span><\/strong><\/span><\/pre>\n
 Przyk\u0142ad 3: U\u017cywanie Cbind<\/strong><\/span><\/h3>\n
 Poni\u017cszy kod pokazuje, jak doda\u0107 kolumn\u0119 do ramki danych za pomoc\u0105 funkcji cbind<\/a> , kt\u00f3ra jest skr\u00f3tem od kolumny-bind<\/em> :<\/span><\/p>\n

 W rzeczywisto\u015bci mo\u017cesz u\u017cy\u0107 funkcji cbind, aby doda\u0107 wiele nowych kolumn jednocze\u015bnie:<\/span><\/p>\n
 #define new columns to add\nnew1 <- c(3, 3, 6, 7, 8)\nnew2 <- c(13, 14, 16, 17, 20) \n<\/span>\n#add columns called 'new1' and 'new2'\ndf_new <- cbind<\/span> (df, new1, new2)\n<\/span>\n#view new data frame\ndf_new\n\n  ab new1 new2\n1 to 45 3 13\n2 B 56 3 14\n3 C 54 6 16\n4 D 57 7 17\n5 E 59 8 20\n<\/span><\/span><\/strong><\/span><\/pre>\n
 Bonus: zdefiniuj nazwy kolumn<\/strong><\/span><\/h3>\n
 Po dodaniu jednej lub wi\u0119kszej liczby kolumn do ramki danych mo\u017cna u\u017cy\u0107 funkcji colnames()<\/strong> w celu okre\u015blenia nazw kolumn nowej ramki danych:<\/span><\/p>\n
 #create data frame\ndf <- data. frame<\/span> (a = c('A', 'B', 'C', 'D', 'E'),\n                 b = c(45, 56, 54, 57, 59),\n                 new1 = c(3, 3, 6, 7, 8),\n                 new2 = c(13, 14, 16, 17, 20))\n\n#view data frame\n<\/span>df\n\n  ab new1 new2\n1 to 45 3 13\n2 B 56 3 14\n3 C 54 6 16\n4 D 57 7 17\n5 E 59 8 20\n\n#specify column names\n<\/span>colnames<\/span> (df) <- c('a', 'b', 'c', 'd')\n\n#view data frame\n<\/span>df\n\n  abcd\n1 to 45 3 13\n2 B 56 3 14\n3 C 54 6 16\n4 D 57 7 17\n5 E 59 8 20\n<\/span><\/span><\/strong><\/span><\/pre>\n
