Anda dapat menggunakan fungsi now()<\/a> untuk menghitung jumlah baris dalam bingkai data di R:<\/span><\/p>\n

 #count total rows in data frame<\/span>\nnrow(df)\n\n#count total rows with no NA values in any column of data frame\n<\/span>nrow(na. omit<\/span> (df))\n\n#count total rows with no NA values in specific column of data frame<\/span>\nnrow(df[ !<\/span> is. na<\/span> (df$column_name),])\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan fungsi nrow()<\/strong> dalam praktiknya.<\/span><\/p>\n
 Contoh 1: Hitung jumlah baris<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung jumlah baris dalam bingkai data:<\/span><\/p>\n
 #create data frame<\/span>\ndf <- data. frame<\/span> (var1=c(1, 3, 3, 4, 5),\n                 var2=c(7, 7, 8, 6, 2),\n                 var3=c(9, 9, 6, 6, 8),\n                 var4=c(1, 1, 2, 8, 9))\n\n#view data frame<\/span>\ndf\n\n  var1 var2 var3 var4\n1 1 7 9 1\n2 3 7 9 1\n3 3 8 6 2\n4 4 6 6 8\n5 5 2 8 9\n\n#count total rows in data frame<\/span>\nnrow(df)\n\n[1] 5<\/strong><\/pre>\n
 Ada total 5<\/strong> baris dalam bingkai data ini.<\/span><\/p>\n
 Contoh 2: Hitung baris tanpa nilai NA di kolom mana pun<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung jumlah baris dalam bingkai data tanpa nilai NA di kolom mana pun:<\/span><\/p>\n
 #create data frame<\/span>\ndf <- data. frame<\/span> (var1=c(1, 3, 3, 4, 5),\n                 var2=c(7, 7, 8, NA, 2),\n                 var3=c(9, 9, NA, 6, 8),\n                 var4=c(1, 1, 2, 8, 9))\n\n#view data frame<\/span>\ndf\n\n  var1 var2 var3 var4\n1 1 7 9 1\n2 3 7 9 1\n3 3 8 NA 2\n4 4 NA 6 8\n5 5 2 8 9\n\n#count total rows in data frame with no NA values in any column of data frame\nnrow(na. omit<\/span> (df))<\/span><\/span>\n\n[1] 3<\/strong><\/pre>\n
 Ada total 3<\/strong> baris dalam bingkai data ini yang tidak memiliki nilai NA di kolom mana pun.<\/span><\/p>\n
 Contoh 3: Hitung baris tanpa nilai NA pada kolom tertentu<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung jumlah baris dalam bingkai data tanpa nilai NA di kolom mana pun:<\/span><\/p>\n
 #create data frame<\/span>\ndf <- data. frame<\/span> (var1=c(1, 3, 3, 4, 5),\n                 var2=c(7, 7, 8, NA, 2),\n                 var3=c(9, NA, NA, 6, 8),\n                 var4=c(1, 1, 2, 8, 9))\n\n#view data frame<\/span>\ndf\n\n  var1 var2 var3 var4\n1 1 7 9 1\n2 3 7 NA 1\n3 3 8 NA 2\n4 4 NA 6 8\n5 5 2 8 9\n\n#count total rows in data frame with no NA values in 'var2' column of data frame\n<\/span>nrow(df[ !<\/span> is. na<\/span> (df$var2),])\n\n[1] 4<\/strong><\/pre>\n
 Ada total 4<\/strong> baris dalam bingkai data ini yang tidak memiliki nilai NA di kolom “var2”.<\/span><\/p>\n
