Ada dua cara dasar untuk menghitung statistik ringkasan grup di R:<\/span><\/p>\n

Metode 1: Gunakan tapply() dari Basis R<\/strong><\/span><\/p>\n

 tapply(df$value_col, df$group_col, summary)\n<\/strong><\/pre>\n
 Metode 2: Gunakan group_by() dari paket dplyr<\/strong><\/span><\/p>\n
 library<\/span> (dplyr)\n\ndf %>%\n  group_by<\/span> (group_col) %>% \n  summarize<\/span> (min = min(value_col),\n            q1 = quantile(value_col, 0.25<\/span> ),\n            median = median(value_col),\n            mean = mean(value_col),\n            q3 = quantile(value_col, 0.75<\/span> ),\n            max = max(value_col))<\/strong><\/span><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan masing-masing metode dalam praktik.<\/span><\/p>\n
 Metode 1: Gunakan tapply() dari Basis R<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menggunakan fungsi tapply()<\/strong> di R untuk menghitung statistik ringkasan berdasarkan grup:<\/span><\/p>\n
 #create data frame\n<\/span>df <- data. frame<\/span> (team=c('A', 'A', 'A', 'A', 'B', 'B', 'B', 'B'),\n                 points=c(99, 68, 86, 88, 95, 74, 78, 93),\n                 assists=c(22, 28, 31, 35, 34, 45, 28, 31),\n                 rebounds=c(30, 28, 24, 24, 30, 36, 30, 29))\n\n#calculate summary statistics of 'points' grouped by 'team'\n<\/span>tapply(df$points, df$team, summary)\n\n$A\n   Min. 1st Qu. Median Mean 3rd Qu. Max. \n  68.00 81.50 87.00 85.25 90.75 99.00 \n\n$B\n   Min. 1st Qu. Median Mean 3rd Qu. Max. \n   74.0 77.0 85.5 85.0 93.5 95.0 \n<\/span><\/span><\/strong><\/pre>\n
 Metode 2: Gunakan group_by() dari paket dplyr<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menggunakan fungsi group_by()<\/strong> dan ringkasan()<\/strong> dalam paket dplyr<\/a> untuk menghitung statistik ringkasan berdasarkan grup:<\/span><\/p>\n
 library<\/span> (dplyr)<\/span>\n\n#create data frame\n<\/span>df <- data. frame<\/span> (team=c('A', 'A', 'A', 'A', 'B', 'B', 'B', 'B'),\n                 points=c(99, 68, 86, 88, 95, 74, 78, 93),\n                 assists=c(22, 28, 31, 35, 34, 45, 28, 31),\n                 rebounds=c(30, 28, 24, 24, 30, 36, 30, 29))\n\n#calculate summary statistics of 'points' grouped by 'team'\n<\/span>df %>%\n  group_by<\/span> (team) %>% \n  summarize<\/span> (min = min(points),\n            q1 = quantile(points, 0.25<\/span> ),\n            median = median(points),\n            mean = mean(points),\n            q3 = quantile(points, 0.75<\/span> ),\n            max = max(points))\n\n# A tibble: 2 x 7\n  team min q1 median mean q3 max\n         \n1 A 68 81.5 87 85.2 90.8 99\n2 B 74 77 85.5 85 93.5 95\n<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa kedua metode memberikan hasil yang persis sama.<\/span><\/p>\n
 Perlu dicatat bahwa pendekatan dplyr kemungkinan akan lebih cepat untuk frame data yang lebih besar, namun kedua metode akan bekerja sama pada frame data yang lebih kecil.<\/span><\/p>\n
