\n

Anda dapat menggunakan metode berikut untuk menciutkan teks menurut grup dalam bingkai data di R:<\/span><\/p>\n

Metode 1: Kurangi teks berdasarkan grup menggunakan Basis R<\/strong><\/span><\/p>\n

 aggregate(text_var ~ group_var, data=df, FUN=paste, collapse='')<\/strong><\/pre>\n
 Metode 2: Kurangi teks berdasarkan grup menggunakan dplyr<\/strong><\/span><\/p>\n
 library<\/span> (dplyr)\n\ndf %>%\n  group_by(group_var) %>%\n  summarize(text=paste(text_var, collapse=''))\n<\/strong><\/pre>\n
 Metode 3: Mengurangi teks berdasarkan kelompok menggunakan data.table<\/strong><\/span><\/p>\n
 library<\/span> (data.table)\n\ndt <- as. data<\/span> . table<\/span> (df)\n\ndt[, list(text_var=paste(text_var, collapse='')), by=group_var]<\/strong><\/pre>\n
 Tutorial ini menjelaskan cara menggunakan setiap metode dalam praktik dengan kerangka data berikut:<\/span><\/p>\n
 #create data frame\n<\/span>df <- data. frame<\/span> (team=c('A', 'A', 'A', 'B', 'B', 'B'),\n                 position=c('Guard', 'Guard', 'Forward',\n                            'Guard', 'Forward', 'Center'))\n\n#view data frame\n<\/span>df\n\n  team position\n1A Guard\n2 A Guard\n3 A Forward\n4 B Guard\n5B Forward\n6B Center\n<\/strong><\/span><\/pre>\n
 Contoh 1: Mengurangi teks berdasarkan grup menggunakan Basis R<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara mengurangi teks kolom posisi<\/strong> , dikelompokkan berdasarkan kolom tim<\/strong> menggunakan fungsi Aggregate()<\/strong> dari database R:<\/span><\/p>\n
 #collapse position values by team \n<\/span>aggregate(position ~ team, data=df, FUN=paste, collapse='')\n\n  team position\n1A GuardGuardForward\n2 B GuardForwardCenter\n<\/strong><\/pre>\n
 Perhatikan bahwa setiap nilai teks di kolom posisi<\/strong> telah diciutkan menjadi satu nilai, dikelompokkan berdasarkan nilai di kolom tim<\/strong> .<\/span><\/p>\n
 Contoh 2: Mengurangi teks berdasarkan grup menggunakan dplyr<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara menciutkan teks di kolom posisi<\/strong> , dikelompokkan berdasarkan kolom tim<\/strong> menggunakan fungsi summarise()<\/strong> dari paket dplyr:<\/span><\/p>\n
 library<\/span> (dplyr)\n\n#collapse position values by team\n<\/span>df %>%\n  group_by(group_var) %>%\n  summarize(text=paste(text_var, collapse=''))\n\n# A tibble: 2 x 2\n  team text              \n                \n1A GuardGuardForward \n2 B GuardForwardCenter\n<\/strong><\/pre>\n
 Perhatikan bahwa setiap nilai teks di kolom posisi<\/strong> telah diciutkan menjadi satu nilai, dikelompokkan berdasarkan nilai di kolom tim<\/strong> .<\/span><\/p>\n
 Contoh 3: Mengurangi teks berdasarkan kelompok menggunakan data.table<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara menciutkan teks di kolom Posisi<\/strong> , dikelompokkan berdasarkan kolom Tim<\/strong> menggunakan fungsi dalam paket data.table:<\/span><\/p>\n
 library<\/span> (data.table)\n\n#convert data frame to data table\n<\/span>dt <- as. data<\/span> . table<\/span> (df)\n\n#collapse position values by team<\/span>\ndt[, list(text_var=paste(text_var, collapse='')), by=group_var]\n\n   team position\n1: A GuardGuardForward\n2: B GuardForwardCenter\n<\/strong><\/pre>\n
 Setiap nilai teks di kolom posisi<\/strong> telah diciutkan menjadi satu nilai, dikelompokkan berdasarkan nilai di kolom tim<\/strong> .<\/span><\/p>\n

 Tutorial berikut menjelaskan cara melakukan tugas umum lainnya di R:<\/span><\/p>\n
