R中的寬到長（縱向）數據轉換

Question

我想知道您是否可以幫助我將數據轉換為縱向格式。 我有一個數據集如下（20個變量）：

ptno    E0sex   calpcvd calcvdea    calrxgp age.baseline    age.year1   age.year2   age.year3   age.year4   age.year5   age.year6   Baseline    year1   year2   year3   year4   year5   year6   duration1
10021001    1   0   0   1   81.3744 82.3744 83.3744 84.3744 85.3744 86.3744 87.3744 0.66    0.68    0.64    0.64    0.38    8   8   6.5
10021002    1   0   0   2   81.18822    82.18822    83.18822    84.18822    85.18822    86.18822    87.18822    0.64    9   9   9   9   9   9   0.989041096
10021003    1   0   0   1   80.32307    81.32307    82.32307    83.32307    84.32307    85.32307    86.32307    0.63    8   9   9   9   9   9   1.21369863
10021004    1   0   0   1   87.00343    88.00343    89.00343    90.00343    91.00343    92.00343    93.00343    0.72    8   9   9   9   9   9   1.347945205
10021005    1   0   0   2   82.42026    83.42026    84.42026    85.42026    86.42026    87.42026    88.42026    0.74    8   8   8   8   8   9   5.052054795
10021006    1   0   0   2   81.54962    82.54962    83.54962    84.54962    85.54962    86.54962    87.54962    0.59    8   8   8   8   9   9   4.208219178

我想重新排列，例如（年齡全部合並為“年齡”和基准，year1 ...合並為實用程序：

id  obs E0sex   calpcvd calcvdea    calrxgp age utility duration
10021001    1   1   0   0   1   81.3744 0.66    6.5
10021001    2   1   0   0   1   82.3744 0.68    6.5
10021001    3   1   0   0   1   83.3744 0.64    6.5
10021001    4   1   0   0   1   84.3744 0.64    6.5
10021001    5   1   0   0   1   85.3744 0.38    6.5
10021001    6   1   0   0   1   86.3744 8   6.5

10021002    2   1   0   0   2   82.18822    9   0.989041096
10021002    3   1   0   0   2   83.18822    9   0.989041096
10021002    4   1   0   0   2   84.18822    9   0.989041096
10021002    5   1   0   0   2   85.18822    9   0.989041096
10021002    6   1   0   0   2   86.18822    9   0.989041096
10021002    7   1   0   0   2   87.18822    9   0.989041096

最好的方法是什么？

假設您的數據是樣本：
