Anda dapat menggunakan sintaks berikut untuk menghitung rata-rata geometrik sekumpulan angka di R:<\/span><\/p>\n

 exp(mean(log(x)))\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan fungsi ini dalam praktiknya.<\/span><\/p>\n
 Contoh 1: Hitung mean geometrik vektor<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung rata-rata geometri suatu vektor di R:<\/span><\/p>\n
 #definevector<\/span>\nx <- c(4, 8, 9, 9, 12, 14, 17)\n\n#calculate geometric mean of values in vector<\/span>\nexp(mean(log(x)))\n\n[1] 9.579479\n<\/strong><\/pre>\n
 Contoh 2: Hitung rata-rata geometri suatu vektor yang nol<\/strong><\/span><\/h3>\n
 Jika vektor Anda berisi angka nol atau negatif, rumus di atas akan menghasilkan 0 atau NaN.<\/span><\/p>\n
 Untuk mengabaikan angka nol dan angka negatif saat menghitung mean geometrik, Anda dapat menggunakan rumus berikut:<\/span><\/p>\n
 #define vector with some zeros and negative numbers<\/span>\nx <- c(4, 8, 9, 9, 12, 14, 17, 0, -4)\n\n#calculate geometric mean of values in vector<\/span>\nexp(mean(log(x[x ><\/span> 0])))\n\n[1] 9.579479<\/strong><\/pre>\n
 Contoh 3: Hitung rata-rata geometrik kolom-kolom dalam bingkai data<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung rata-rata geometrik kolom dalam bingkai data:<\/span><\/p>\n
 #define data frame<\/span>\ndf <- data. frame<\/span> (a=c(1, 3, 4, 6, 8, 8, 9),\n                 b=c(7, 8, 8, 7, 13, 14, 16),\n                 c=c(11, 13, 13, 18, 19, 19, 22),\n                 d=c(4, 8, 9, 9, 12, 14, 17))\n\n#calculate geometric mean of values in column 'a'<\/span>\nexp(mean(log(df$a)))\n\n[1] 4.567508<\/strong><\/pre>\n
 Dan kode berikut menunjukkan cara menghitung rata-rata geometrik beberapa kolom dalam bingkai data:<\/span><\/p>\n
 #define data frame<\/span>\ndf <- data. frame<\/span> (a=c(1, 3, 4, 6, 8, 8, 9),\n                 b=c(7, 8, 8, 7, 13, 14, 16),\n                 c=c(11, 13, 13, 18, 19, 19, 22),\n                 d=c(4, 8, 9, 9, 12, 14, 17))\n\n#calculate geometric mean of values in column 'a', 'b', and 'd'<\/span>\napply(df[, c(' a<\/span> ', ' b<\/span> ', ' d<\/span> ')], 2, function<\/span> (x) exp(mean(log(x))))\n\n       abd\n4.567508 9.871128 9.579479<\/strong><\/pre>\n
