在给出以下命令时，它会给出与时间相关的错误。我尝试阅读 .CSV 。列作为日期和时间，问题仍然相同。我不确定日期或格式有什么问题。数据的日期和时间格式为 dd/mm/yyyy hr:min，其中使用练习示例命令可以正常工作。IE

summaryPlot(package_exercisesample)


rm(list = ls())

library(lubridate)

library(readr)

library(openair)

package_exercisesample<- openair::mydata

dat<- read_csv("data.csv")

summaryPlot(dat)

这是我得到的错误

用列规范解析：

cols(

  Date = col_character(),

  ws = col_double(),

  wd = col_double(),

  Co = col_double(),

  No = col_double(),

  O3 = col_double(),

  Pm2.5 = col_double(),

  Pm10 = col_double(),

  So2 = col_double()

)

summaryPlot(dat)

as.POSIXct.default(x) 中的错误： 

  .  do not know how to convert 'x' to class “POSIXct”   

    In addition: Warning messages:

    1: Unknown or uninitialised column: 'date'. 

    2: Unknown or uninitialised column: 'date'. 

3: Unknown or uninitialised column: 'date'.

抱歉，问题已通过将输入日期数据的列名更改为“日期”而不是“日期”来解决
