Anda dapat menggunakan sintaks dasar berikut untuk menginterpolasi nilai yang hilang dalam kolom bingkai data di R:<\/span><\/p>\n

 library<\/span> (dplyr)\nlibrary<\/span> (zoo)\n\ndf <- df %>%\n        mutate(column_name = na. approx<\/span> (column_name))\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan sintaksis ini dalam praktiknya.<\/span><\/p>\n
 Contoh: Interpolasi Nilai yang Hilang di R<\/strong><\/span><\/h2>\n
 Misalkan kita memiliki kerangka data berikut di R yang menunjukkan total penjualan yang dilakukan oleh sebuah toko selama 15 hari berturut-turut:<\/span><\/p>\n
 #create data frame\n<\/span>df <- data. frame<\/span> (day=1:15,\n                 sales=c(3, 6, 8, 10, 14, 17, 20, NA, NA, NA, NA, 35, 39, 44, 49))\n\n#view data frame\n<\/span>df\n\n   day sales\n1 1 3\n2 2 6\n3 3 8\n4 4 10\n5 5 14\n6 6 17\n7 7 20\n8 8 NA\n9 9 NA\n10 10 NA\n11 11 NA\n12 12 35\n13 13 39\n14 14 44\n15 15 49\n<\/strong><\/pre>\n
 Perhatikan bahwa kami kehilangan angka penjualan selama empat hari dalam kerangka data.<\/span><\/p>\n
 Jika kita membuat diagram garis sederhana untuk memvisualisasikan penjualan dari waktu ke waktu, tampilannya akan seperti ini:<\/span> <\/p>\n
 #create line chart to visualize sales\n<\/span>plot(df$sales, type=' o<\/span> ', pch= 16<\/span> , col=' steelblue<\/span> ', xlab=' Day<\/span> ', ylab=' Sales<\/span> ')<\/strong> <\/pre>\n
\"menginterpolasi<\/p>\n
 Untuk mengisi nilai yang hilang, kita dapat menggunakan fungsi na.approx()<\/a> dari paket zoo<\/strong> serta fungsi mutate()<\/a> dari paket dplyr<\/strong> :<\/span><\/p>\n
 library<\/span> (dplyr)\nlibrary<\/span> (zoo)\n\n#interpolate missing values in 'sales' column\n<\/span>df <- df %>%\n        mutate(sales = na. approx<\/span> (sales))\n\n#view updated data frame<\/span>\ndf\n\n   day sales\n1 1 3\n2 2 6\n3 3 8\n4 4 10\n5 5 14\n6 6 17\n7 7 20\n8 8 23\n9 9 26\n10 10 29\n11 11 32\n12 12 35\n13 13 39\n14 14 44\n15 15 49\n<\/strong><\/pre>\n
 Perhatikan bahwa setiap nilai yang hilang telah diganti.<\/span><\/p>\n
 Jika kita membuat diagram garis lain untuk memvisualisasikan bingkai data yang diperbarui, tampilannya akan seperti ini:<\/span> <\/p>\n
 #create line chart to visualize sales\n<\/span>plot(df$sales, type=' o<\/span> ', pch= 16<\/span> , col=' steelblue<\/span> ', xlab=' Day<\/span> ', ylab=' Sales<\/span> ')<\/strong> <\/pre>\n
\"\"<\/p>\n
 Perhatikan bahwa nilai yang dipilih oleh fungsi na.approx()<\/strong> tampaknya cukup cocok dengan tren data.<\/span><\/p>\n
