私のデータは次のようになります:
# A tibble: 6 x 4
name val time x1
<chr> <dbl> <date> <dbl>
1 C Farolillo 7 2016-04-20 51.5
2 C Farolillo 3 2016-04-21 56.3

5 C Farolillo 7 2016-04-24 58.7
6 C Farolillo 9 2016-04-25 59.0
pivot_wider
関数を使用して、name
列に基づいてデータを展開しようとしています。次のコードを使用します。
yy <- d %>%
pivot_wider(., names_from = name, values_from = val)
次の警告メッセージが表示されます。
Warning message:
Values in `val` are not uniquely identified; output will contain list-cols.
* Use `values_fn = list(val = list)` to suppress this warning.
* Use `values_fn = list(val = length)` to identify where the duplicates arise
* Use `values_fn = list(val = summary_fun)` to summarise duplicates
出力は次のようになります。

私はここで問題に言及し、それを解決するために要約統計量を使用することを提案していることを知っています。しかし、私は時系列データを持っているため、毎日は単一の値(複数の値ではない)を持っているため、要約統計を使用したくありません。
問題は、val
列に重複があるためです(つまり、上記の例では7が3回発生する)。
この問題をpivot_widerして克服する方法に関する提案はありますか?
