Ben hayvanat bahçesi kütüphanesini kullanarak denedi yıl sütununu bir tarihe dönüştür.

prices$year = as.Date(as.yearqtr(prices$year, format = "%y/Q%q")) kodunu uygularken NA'ların bir çıktısını alıyorum. Bunu düzeltmenin bir yolu var mı? Hatamın nerede olduğunu göremiyorum.

Düzenleme:

structure(list(US.avg = c(296.9, 296.8, 287.51, 287.78, 283.97, 
275.78), inflation_adj = c(466.61, 463.1, 446.56, 446.09, 433.97,

As.Date (as.yearqtr) öğesini denediğinizde işe yarar mı? $ Date fiyatlarının sınıfı chr, belki bu benim problemim. – michel

Evet, hala çalışıyor. Gözden geçirilmiş cevaba bakınız. –

Kodunuzun bir kopyasını çalıştırırken bir hata alıyorum. as.Date (as.yearqtr (fiyatlar $ date, format = "$% Y/Q% q")) verir: as.yearqtr (as.numeric (x)) 'de hata: (liste) nesnesi zorlanamaz 'çift' yazmak için. Anlamıyorum, RStudio'mda bir şey yanlış olmalı. – michel
