Anda dapat menggunakan fungsi log()<\/strong> di R untuk menghitung log suatu nilai dengan basis tertentu:<\/span><\/p>\n

 #calculate log of 9 with base 3<\/span>\nlog(9, base=3)\n<\/strong><\/pre>\n
 Jika Anda tidak menentukan basis, R akan menggunakan nilai basis default e<\/em> .<\/span><\/p>\n
 #calculate log of 9 with base e<\/em><\/span>\nlog(9)\n\n[1] 2.197225\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan fungsi ini dalam praktiknya.<\/span><\/p>\n
 Contoh 1: Hitung log dari satu nilai<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung log nilai individual di R menggunakan basis yang berbeda:<\/span><\/p>\n
 #calculate log of 100 with base e<\/em><\/span>\nlog(100)\n\n[1] 4.60517\n\n#calculate log of 100 with base 10\n<\/span>log(100, base=10)\n\n[1] 2\n\n#calculate log of 100 with base 3\n<\/span>log(100, base=3)\n\n[1] 4.191807\n<\/strong><\/pre>\n
 Contoh 2: Menghitung Nilai Log dalam Vektor<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung log setiap nilai vektor di R:<\/span><\/p>\n
 #definevector\nx <- c(3, 6, 12, 16, 28, 45)<\/span>\n\n#calculate log of each value in vector with base e<\/em><\/span>\nlog(x)\n\n[1] 1.098612 1.791759 2.484907 2.772589 3.332205 3.806662\n<\/strong><\/pre>\n
 Contoh 3: Hitung nilai log dalam bingkai data<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung nilai log di kolom tertentu dari bingkai data di R:<\/span><\/p>\n
 #define data frame\ndf <- data. frame<\/span> (var1=c(1, 3, 3, 4, 5),\n                 var2=c(7, 7, 8, 3, 2),\n                 var3=c(3, 3, 6, 6, 8),\n                 var4=c(1, 1, 2, 8, 9))\n\n#calculate log of each value in 'var1' column\n<\/span>log(df$var1, base=10)<\/span>\n\n[1] 0.0000000 0.4771213 0.4771213 0.6020600 0.6989700\n<\/span><\/span><\/strong><\/pre>\n
 Dan kode berikut menunjukkan cara menggunakan fungsi sapply()<\/strong> untuk menghitung nilai log di setiap kolom bingkai data:<\/span><\/p>\n
 #define data frame\ndf <- data. frame<\/span> (var1=c(1, 3, 3, 4, 5),\n                 var2=c(7, 7, 8, 3, 2),\n                 var3=c(3, 3, 6, 6, 8),\n                 var4=c(1, 1, 2, 8, 9))\n\n#calculate log of values in every column\n<\/span>sapply(df, function<\/span> (x) log(x, base=10))\n\n          var1 var2 var3 var4\n[1,] 0.0000000 0.8450980 0.4771213 0.0000000\n[2,] 0.4771213 0.8450980 0.4771213 0.0000000\n[3,] 0.4771213 0.9030900 0.7781513 0.3010300\n[4,] 0.6020600 0.4771213 0.7781513 0.9030900\n[5,] 0.6989700 0.3010300 0.9030900 0.9542425\n<\/span><\/span><\/strong><\/pre>\n
