많은 변수가있는 열을 개별 변수 열로 변환하는 방법

Question

끝에 간단한 데이터 집합을 제공합니다.

주어진 시간을 감안할 때, 나는 9 개의 다른 과목에 대한 모든 활동 값을 가지고 있습니다. 는 I 피사체 칼럼 9 개 새로운 변수로 변환되는 것을 달성 할 같은 I는 다음의 구조를 갖고 있음 :

시간, 활동, 제목 1 제목 2, ..., 제목 9

어디 주체 변수에는 값의 해당 항목이 들어 있습니다.

그래서 말에 나는 시간의 모든 지점을 갖고 싶어, 8 개 활동 및

Time | ACTIVITY | Subject1 | Subject2 | ... | Subject9 
    -----| ---------|----------|----------|-----|---------- 
    1995 | A  | example | example |  | example 
    1995 | F  | example | example |  | example 
    1995 | K  | example | example |  | example 
    1995 | J  | example | example |  | example 

...

나는 이미 reshape 명령, reshape wide ACTIVITY, i(Value) j(Subject) string을 시도하지만 난 reshape isn' 의심 내가 원하는 결과를 얻기 위해 여기에 올바른 명령을하십시오.

귀하의 스크린 샷은 다음과 같은 문제를 보여줍니다

이

1. 귀하의 Time 변수 Value 변수가 문자열입니다. 그건 틀렸어. 아마도 이러한 변수의 어딘가에 쓰레기가있을 것입니다. 아마도 머리글이 데이터에 복사되었을 것입니다. list Time if missing(real(Time))은 숫자가 아닌 값을 표시하는 명령의 일종입니다.

2. 변수 Subject 변수에 후행 공백이 표시됩니다. 일관성이 없다면 문제가 발생할 수 있습니다.

3. Subject 변수의 고유 값은 공백이있는 변수 이름의 일부가 될 수 없습니다. 그래서, 우리는 약간의 추가 작업이 필요합니다.

이 코드는 장난감 예제를 생성하고 몇 가지 기술을 보여줍니다. 귀하의 추측과는 달리 reshape이 선택의 명령입니다.
