Anda dapat menggunakan salah satu metode berikut untuk menghitung rata-rata kolom di R:<\/span><\/p>\n

 #calculate mean using column name<\/span>\nmean(df$my_column)\n\n#calculate mean using column name (ignore missing values)\n<\/span>mean(df$my_column, na. rm<\/span> = TRUE<\/span> )\n\n#calculate mean using column position<\/span>\nmean(df[, 1])\n\n#calculation mean of all numeric columns\n<\/span>colMeans(df[sapply(df, is. numeric<\/span> )])\n<\/b><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan setiap metode dengan bingkai data berikut di R:<\/span><\/p>\n
 #create data frame\n<\/span>df <- data. frame<\/span> (team=c('A', 'A', 'A', 'B', 'B', 'B'),\n                 points=c(99, 90, 93, 86, 88, 82),\n                 assists=c(33, 28, 31, 39, NA, 30))\n\n#view data frame\n<\/span>df\n\n  team points assists\n1 A 99 33\n2 A 90 28\n3 A 93 31\n4 B 86 39\n5 B 88 NA\n6 B 82 30\n<\/strong><\/pre>\n
 Contoh 1: Hitung rata-rata menggunakan nama kolom<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung rata-rata kolom “poin” menggunakan nama kolom:<\/span><\/p>\n
 #calculate mean of 'points' column\nmean(df$points)\n\n[1] 89.66667<\/span>\n<\/span><\/strong><\/pre>\n
 Nilai rata-rata pada kolom \u201cpoin\u201d adalah 89.66667<\/strong> .<\/span><\/p>\n
 Contoh 2: Hitung Rata-Rata Menggunakan Nama Kolom (Abaikan Nilai yang Hilang)<\/strong><\/span><\/h3>\n
 Jika kita mencoba menghitung rata-rata kolom yang berisi nilai yang hilang, kita akan mendapatkan NA<\/strong> :<\/span><\/p>\n
 #attempt to calculate mean of 'assists' column\nmean(df$assists)\n\n[1] NA<\/span>\n<\/span><\/strong><\/pre>\n
 Kita perlu menggunakan na.rm=TRUE<\/strong> untuk mengabaikan nilai yang hilang saat menghitung rata-rata kolom:<\/span><\/span><\/p>\n
 #calculate mean of 'assists' column and ignore missing values\nmean(df$assists, na. rm<\/span> = TRUE<\/span> )\n\n[1] 32.2<\/span><\/span><\/strong><\/pre>\n
 Nilai rata-rata pada kolom \u201cbantuan\u201d adalah 32,2<\/strong> .<\/span><\/p>\n
 Contoh 3: Hitung rata-rata menggunakan posisi kolom<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung rata-rata kolom pada posisi indeks 2:<\/span><\/p>\n
 #calculate mean of column in index position 2\nmean(df[, 2])\n\n[1] 89.66667<\/span>\n<\/span><\/strong><\/pre>\n
 Nilai rata-rata kolom pada posisi indeks 2 (kolom \u201cpoin\u201d) adalah 89.66667<\/strong> .<\/span><\/p>\n
 Contoh 4: Hitung rata-rata semua kolom numerik<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung rata-rata semua kolom numerik dalam bingkai data:<\/span><\/p>\n
 #calculate mean of all numeric columns\ncolMeans(df[sapply(df, is. numeric<\/span> )], na. rm<\/span> = TRUE<\/span> )\n\n  assist points \n89.66667 32.20000<\/span>\n<\/span><\/strong><\/pre>\n
 Outputnya menampilkan nilai rata-rata setiap kolom numerik dalam bingkai data.<\/span><\/span><\/p>\n
