Stata veya R'deki gözlemlerden bazı belirli kelimeler nasıl kaldırılır?

Question

İnternette biraz araştırma yaptım ve şimdiye kadar susbstr ile yapılan gözlemlerden ilk/son harfleri kaldırma olasılıklarını buldum, ancak CTRL + F-findandreplace gibi bir komut kullanamadım. Buradaki trick burada, düşmek istediğim kelimelerin nerede olduğunu bilmiyorum!

Benim veri kümesi şöyle görünür:

Herhangi bir öneri Herhangi söz?

Answer 1

İşte, R kullanarak bir cevaptır. İki strateji, ilk R temel işlevini kullanır, ikinci paket stringr'u kullanır. Her ikisi de 3 adım kullanır: i) ilk 7 karakteri kaldırmak; ii) istemediğimiz kalıpları kaldırın, iii) kalan alanı düzeltin.

library(stringr) 

Bu yardımcı olur umarım.

Stata ile benzer bir strateji. Gelecekte, düşünceli ol ve veri örneğini oluşturmak için dataex kullanın. R
