Anda dapat menggunakan fungsi Mean()<\/strong> di R untuk menghitung rata-rata nilai dalam vektor:<\/span><\/p>\n

 mean(x)\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan fungsi ini dalam praktiknya.<\/span><\/p>\n
 Contoh 1: Hitung rata-rata vektor<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung nilai rata-rata suatu vektor di R:<\/span><\/p>\n
 #definevector<\/span>\nx <- c(3, 6, 7, 7, 12, 14, 19, 22, 24)\n\n#calculate mean of vector<\/span>\nmean(x)\n\n[1] 12.66667\n<\/strong><\/pre>\n
 Jika vektor Anda memiliki nilai yang hilang, pastikan untuk menentukan na.rm = TRUE<\/strong> untuk mengabaikan nilai yang hilang saat menghitung rata-rata:<\/span><\/p>\n
 #define vector with some missing values<\/span>\nx <- c(3, 6, 7, 7, NA, 14, NA, 22, 24)\n\n#calculate mean of vector<\/span>\nmean(x, na. rm<\/span> = TRUE<\/span> )\n\n[1] 11.85714\n<\/strong><\/pre>\n
 Anda juga dapat menggunakan argumen trim<\/strong> untuk menghapus sebagian kecil (0 hingga 0,5) pengamatan dari setiap ujung vektor sebelum menghitung rata-rata:<\/span><\/p>\n
 #definevector<\/span>\nx <- c(3, 6, 7, 7, 12, 14, 19, 22, 24)\n\n#calculate mean of vector after trimming 20% of observations off each end<\/span>\nmean(x, trim = 0.2<\/span> )\n\n[1] 12.42857\n<\/strong><\/pre>\n
 Contoh 2: Hitung rata-rata kolom dalam bingkai data<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung nilai rata-rata kolom tertentu dalam bingkai data:<\/span><\/p>\n
 #define data frame<\/span>\ndf <- data. frame<\/span> (a=c(3, 6, 7, 7, 12, 14, 19, 22, 24),\n                 b=c(4, 4, 5, 12, 13, 14, 9, 1, 2),\n                 c=c(5, 6, 6, 3, 5, 5, 6, 19, 25))\n\n#calculate mean of column 'a'\n<\/span>mean(df$a)\n\n[1] 12.66667\n<\/strong><\/pre>\n
 Contoh 3: Hitung rata-rata beberapa kolom dalam bingkai data<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menggunakan fungsi apply()<\/strong> untuk menghitung rata-rata beberapa kolom dalam bingkai data:<\/span><\/p>\n
 #define data frame<\/span>\ndf <- data. frame<\/span> (a=c(3, 6, 7, 7, 12, 14, 19, 22, 24),\n                 b=c(4, 4, 5, 12, 13, 14, 9, 1, 2),\n                 c=c(5, 6, 6, 3, 5, 5, 6, 19, 25))\n\n#calculate mean of columns 'a' and 'c'\n<\/span>apply(df[, c(' a<\/span> ', ' c<\/span> ')], 2, mean)\n\n        ac\n12.666667 8.888889<\/strong><\/pre>\n
