Fungsi Where()<\/strong> di R mengembalikan posisi elemen dalam vektor logika yang TRUE<\/strong> .<\/span><\/p>\n

Tutorial ini memberikan beberapa contoh penggunaan praktis fungsi ini.<\/span><\/p>\n

Contoh 1: Temukan elemen dalam vektor<\/strong><\/span><\/h3>\n

Kode berikut menunjukkan cara mencari posisi semua elemen vektor sama dengan 5:<\/span><\/p>\n

 #create data<\/span>\ndata <- c(1, 2, 2, 3, 4, 4, 4, 5, 5, 12)\n\n#find the position of all elements equal to 5\n<\/span>which<\/span> (data ==<\/span> 5)\n\n[1] 8 9<\/strong><\/pre>\n
 Kita melihat bahwa elemen-elemen pada posisi 8<\/strong> dan 9<\/strong> pada vektor sama dengan nilai 5.<\/span><\/p>\n
 Kita juga dapat mencari posisi semua elemen suatu vektor yang tidak<\/em> sama dengan 5:<\/span><\/p>\n
 #find the position of all elements not<\/em> equal to 5\n<\/span>which<\/span> (data !=<\/span> 5)\n\n[1] 1 2 3 4 5 6 7 10\n<\/strong><\/pre>\n
 Kita juga dapat menemukan elemen mana yang berada di antara dua nilai atau di luar dua nilai:<\/span><\/p>\n
 #find the position of all elements with values between 2 and 4\n<\/span>which<\/span> (data >=<\/span> 2 &<\/span> data <=<\/span> 4)\n\n[1] 2 3 4 5 6 7\n\n#find the position of all elements with values outside of 2 and 4\n<\/span>which<\/span> (data <<\/span> 2 |<\/span> data ><\/span> 4)\n\n[1] 1 8 9 10<\/strong><\/pre>\n
 Contoh 2: Menghitung Kemunculan dalam Vektor<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menggunakan fungsi length()<\/strong> untuk mencari jumlah elemen dalam vektor yang lebih besar dari nilai tertentu:<\/span><\/p>\n
 #createdata\ndata <- c(1, 2, 2, 3, 4, 4, 4, 5, 5, 12)<\/span>\n\n#find number of elements greater than 4<\/span>\nlength<\/span> ( which<\/span> (data ><\/span> 4))\n\n[1] 3\n<\/strong><\/pre>\n
 Terlihat ada 3 elemen pada vektor ini yang nilainya lebih besar dari 4.<\/span><\/p>\n
 Contoh 3: Temukan baris dalam bingkai data<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara mengembalikan baris dalam bingkai data yang berisi nilai maks atau min pada kolom tertentu:<\/span><\/p>\n
 #create data frame\ndf <- data. frame<\/span> (x = c(1, 2, 2, 3, 4, 5),\n                 y = c(7, 7, 8, 9, 9, 9),\n                 z = c('A', 'B', 'C', 'D', 'E', 'F'))<\/span>\n\n#view data frame\ndf\n\n  X Y Z\n1 1 7 A\n2 2 7 B\n3 2 8 C\n4 3 9 D\n5 4 9 E\n6 5 9 F<\/span>\n\n#return row that contains the max value in column x<\/em>\ndf[ which<\/span> . max<\/span> (df$x), ]\n\n  X Y Z\n6 5 9 F\n\n#return row that contains the min value in column x<\/em><\/span>\ndf[ which<\/span> . min<\/span> (df$x), ]\n\n  X Y Z\n1 1 7 A\n<\/span><\/span><\/strong><\/pre>\n
 Contoh 4: himpunan bagian demi baris dalam bingkai data<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara membagi bingkai data menjadi baris-baris yang memenuhi kriteria tertentu:<\/span><\/p>\n
 #create data frame\ndf <- data. frame<\/span> (x = c(1, 2, 2, 3, 4, 5),\n                 y = c(7, 7, 8, 9, 9, 9),\n                 z = c('A', 'B', 'C', 'D', 'E', 'F'))<\/span>\n\n#view data frame\ndf\n\n  X Y Z\n1 1 7 A\n2 2 7 B\n3 2 8 C\n4 3 9 D\n5 4 9 E\n6 5 9 F<\/span>\n\n#return subset of data frame where values in column y are greater than 8\ndf[ which<\/span> (df$y ><\/span> 8), ]\n\n  X Y Z\n4 3 9 D\n5 4 9 E\n6 5 9 F\n<\/span><\/span><\/strong><\/pre>\n
