Anda dapat menggunakan operator tanda dolar ( $<\/strong> ) di R untuk membuat dan mengakses variabel dalam daftar dan bingkai data.<\/span><\/p>\n

Contoh berikut menunjukkan empat cara umum untuk menggunakan operator ini dalam praktiknya.<\/span><\/p>\n

Contoh 1: Gunakan tanda dolar untuk membuat variabel dalam daftar<\/strong><\/span><\/h3>\n

Misalkan kita membuat daftar berikut di R:<\/span><\/p>\n

 #create list\nmy_list <- list(A= c(' X<\/span> ', ' Y<\/span> ', ' Z<\/span> '),\n                B=20,\n                C=1:5)\n\n#view list\n<\/span>my_list\n\n$A\n[1] \u201cX\u201d \u201cY\u201d \u201cZ\u201d\n\n$B\n[1] 20\n\n$C\n[1] 1 2 3 4 5<\/span><\/span><\/span><\/span><\/strong><\/pre>\n
 Kita dapat menggunakan operator tanda dolar ( $<\/strong> ) untuk membuat variabel baru dalam daftar ini:<\/span><\/p>\n
 #create new variable in list\nmy_list$D <- c(' Hey<\/span> ', ' Hi<\/span> ', ' Hello<\/span> ')\n<\/span>\n#view updated list\nmy_list\n\n$A\n[1] \u201cX\u201d \u201cY\u201d \u201cZ\u201d\n\n$B\n[1] 20\n\n$C\n[1] 1 2 3 4 5\n\n$D\n[1] \u201cHey\u201d \u201cHi\u201d \u201cHello\u201d\n<\/span><\/span><\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa variabel baru D<\/strong> telah ditambahkan ke daftar.<\/span><\/p>\n
 Contoh 2: Gunakan tanda dolar untuk mengakses variabel dalam daftar<\/strong><\/span><\/h3>\n
 Kita juga dapat menggunakan operator tanda dolar ( $<\/strong> ) untuk mengakses variabel tertentu dalam daftar.<\/span><\/p>\n
 Misalnya, kita dapat menggunakan kode berikut untuk mengakses variabel C<\/strong> dalam daftar:<\/span><\/p>\n
 #create list\n<\/span>my_list <- list(A= c(' X<\/span> ', ' Y<\/span> ', ' Z<\/span> '),\n                B=20,\n                C=1:5)<\/span>\n\n#access variable C\nmy_list$C<\/span>\n\n[1] 1 2 3 4 5<\/span><\/span><\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa hanya nilai variabel C<\/strong> yang dikembalikan.<\/span><\/span><\/p>\n
 Contoh 3: Gunakan tanda dolar untuk membuat variabel dalam bingkai data<\/strong><\/span><\/h3>\n
 Misalkan kita membuat bingkai data berikut di R:<\/span><\/p>\n
 #create data frame\ndf <- data. frame<\/span> (team=c(' Mavs<\/span> ', ' Spurs<\/span> ', ' Rockets<\/span> ', ' Nets<\/span> '),\n                 dots=c(140, 115, 109, 98))<\/span>\n\n#view data frame\ndf\n\n     team points\n1 Mavs 140\n2 Spurs 115\n3 Rockets 109\n4 Nets 98\n<\/span><\/span><\/span><\/span><\/strong><\/pre>\n
 Kita dapat menggunakan operator tanda dolar ( $<\/strong> ) untuk membuat variabel baru dalam bingkai data yang disebut assist<\/strong> :<\/span><\/p>\n
 #create new variable called assists\ndf$assists <- c(20, 25, 29, 49)\n\n#view updated data frame\n<\/span>df\n\n     team points assists\n1 Mavs 140 20\n2 Spurs 115 25\n3 Rockets 109 29\n4 Nets 98 49<\/span><\/span><\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa variabel assist<\/strong> baru telah ditambahkan ke bingkai data.<\/span><\/p>\n
 Contoh 4: Gunakan tanda dolar untuk mengakses variabel dalam bingkai data<\/strong><\/span><\/h3>\n
 Kita juga dapat menggunakan operator tanda dolar ( $<\/strong> ) untuk mengakses variabel tertentu dalam bingkai data.<\/span><\/p>\n
 Misalnya, kita dapat menggunakan kode berikut untuk mengakses variabel poin<\/strong> dalam bingkai data:<\/span><\/p>\n
 #create data frame\ndf <- data. frame<\/span> (team=c(' Mavs<\/span> ', ' Spurs<\/span> ', ' Rockets<\/span> ', ' Nets<\/span> '),\n                 dots=c(140, 115, 109, 98))<\/span>\n\n#access values for points\ndf$points\n\n[1] 140 115 109 98<\/span>\n<\/span><\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa hanya nilai variabel poin<\/strong> yang dikembalikan.<\/span><\/p>\n
