Mis datos se ven así:
# 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
3 C Farolillo 7 2016-04-22 56.3
4 C Farolillo 13 2016-04-23 57.9
5 C Farolillo 7 2016-04-24 58.7
6 C Farolillo 9 2016-04-25 59.0
Estoy tratando de usar la pivot_wider
función para expandir los datos en función de la name
columna. Yo uso el siguiente código:
yy <- d %>%
pivot_wider(., names_from = name, values_from = val)
Lo que me da el siguiente mensaje de advertencia:
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
El resultado se ve así:
time x1 out1 out2
2016-04-20 51.50000 <dbl> <dbl>
2 2016-04-21 56.34615 <dbl> <dbl>
3 2016-04-22 56.30000 <dbl> <dbl>
4 2016-04-23 57.85714 <dbl> <dbl>
5 2016-04-24 58.70968 <dbl> <dbl>
6 2016-04-25 58.96774 <dbl> <dbl>
Sé que aquí se menciona el problema y para resolverlo sugieren usar estadísticas resumidas. Sin embargo, tengo datos de series de tiempo y, por lo tanto, no quiero usar estadísticas de resumen, ya que cada día tiene un valor único (y no valores múltiples).
Sé que el problema se debe a que la val
columna tiene duplicados (es decir, en el ejemplo anterior 7 ocurre 3 veces.
¿Alguna sugerencia sobre cómo pivot_wider y superar este problema?
