Seringkali Anda mungkin ingin menghitung hanya<\/em> jumlah baris dalam bingkai data R yang memenuhi kriteria tertentu. Untungnya, hal ini mudah dilakukan dengan menggunakan sintaks dasar berikut:<\/span><\/p>\n

 sum(df$column == value, na.rm= TRUE<\/span> )\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan sintaks ini dalam praktiknya pada bingkai data berikut:<\/span><\/p>\n
 #create data frame<\/span>\ndata <- data.frame(team=c('Mavs', 'Mavs', 'Spurs', 'Spurs', 'Lakers'),\n                   points=c(14, NA, 8, 17, 22),\n                   rebounds=c(8, 5, 5, 9, 12))\n\n#view data frame\n<\/span>data\n\n    team points rebounds\n1 Mavs 14 8\n2 Mavs NA 5\n3 Spurs 8 5\n4 Spurs 17 9\n5 Lakers 22 12\n<\/b><\/pre>\n
 Contoh 1: Hitung baris yang sama dengan nilai tertentu<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung jumlah baris di mana nama tim sama dengan “Mavs”:<\/span><\/p>\n
 sum(data$team == ' Mavs<\/span> ')\n\n[1] 2\n<\/strong><\/pre>\n
 Kode berikut menunjukkan cara menghitung jumlah baris di mana nama tim sama dengan “Mavs” atau “Lakers”:<\/span><\/p>\n
 sum(data$team == ' Mavs<\/span> ' | data$team == ' Lakers<\/span> ')\n\n[1] 3<\/strong><\/pre>\n
 Kode berikut menunjukkan cara menghitung jumlah baris dimana nama tim tidak<\/em> sama dengan “Lakers”:<\/span><\/p>\n
 sum(data$team != ' Lakers<\/span> ')\n\n[1] 4<\/strong><\/pre>\n
 Contoh 2: menghitung baris yang lebih besar atau sama dengan nilai tertentu<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung jumlah garis yang titiknya lebih besar dari 10:<\/span><\/p>\n
 sum(data$points > 10, na.rm= TRUE<\/span> )\n\n[1] 3<\/strong><\/pre>\n
 Kode berikut menunjukkan cara menghitung jumlah baris yang pentalannya kurang dari atau sama dengan 9:<\/span><\/p>\n
 sum(data$rebounds <= 9, na.rm= TRUE<\/span> )\n\n[1] 4<\/strong><\/pre>\n
 Contoh 3: Hitung garis di antara dua nilai<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung jumlah garis yang titik-titiknya antara 10 dan 20:<\/span><\/p>\n
 sum(data$points > 10 & data$points < 20, na.rm= TRUE<\/span> )\n\n[1] 2<\/strong><\/pre>\n
 Kode berikut menunjukkan cara menghitung jumlah baris yang memantul antara 8 dan 10:<\/span><\/p>\n
 sum(data$rebounds > 8 & data$rebounds < 10, na.rm= TRUE<\/span> )\n\n[1] 1<\/strong><\/pre>\n
