当我尝试运行以下函数时:
foo <- air_reserve %>%
mutate(reserve_date = date(reserve_datetime),
reserve_hour = hour(reserve_datetime),
reserve_wday = wday(reserve_datetime, label = TRUE),
visit_date = date(visit_datetime),
visit_hour = hour(visit_datetime),
visit_wday = wday(visit_datetime, label = TRUE),
diff_hour = time_length(visit_datetime - reserve_datetime, unit = "hour"),
diff_day = time_length(visit_datetime - reserve_datetime, unit = "day")
)
我收到以下错误:
Error in mutate_impl(.data, dots) :
Evaluation error: non-numeric argument to binary operator.
如何解决这个问题？
注意:
foo函数取自此 link
最佳答案
哇!!
我通过以下代码解决了这个问题:
foo <- air_reserve %>%
mutate(reserve_date = date(reserve_datetime),
reserve_hour = hour(reserve_datetime),
reserve_wday = wday(reserve_datetime, label = TRUE),
visit_date = date(visit_datetime),
visit_hour = hour(visit_datetime),
visit_wday = wday(visit_datetime, label = TRUE),
diff_hour = time_length(as.numeric(visit_datetime) - as.numeric(reserve_datetime), unit = "hour"),
diff_day = time_length(as.numeric(visit_datetime) - as.numeric(reserve_datetime), unit = "day")
)
关于r - mutate_impl(.data, 点) : Evaluation error: non-numeric argument to binary operator 中的错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47574204/
