我正在尝试通过阅读此 googledoc googlesheets4
。
该文件包含 3 列:
id
, 作为字符start_date
/end_date
:此列包含日期(格式为2020-01-31
)和文本字符串(即字符串为in_stock
和in_use
)
我让任何知道链接的人都可以阅读这个 googlesheet 。
我读取数据帧如下:
suppressPackageStartupMessages({
library(tidyverse)
library(lubridate)
library(readxl)
library(googlesheets4)})
df <- read_sheet('1rS_Zw4Qc8S4oV5-u_YZJACNBqu3VDQUMf9N_dGrLUo8',sheet = 'test_import')
虽然最初看起来不错,但当我检查它是如何导入的时,结果如下:
> head(df)
# A tibble: 6 x 3
id start_date end_date
<dbl> <list> <list>
1 1 <chr [1]> <chr [1]>
2 2 <chr [1]> <chr [1]>
3 3 <chr [1]> <chr [1]>
4 4 <chr [1]> <chr [1]>
5 5 <chr [1]> <chr [1]>
6 6 <chr [1]> <chr [1]>
虽然 RStudio 在预览中正确显示了数据框,但列start_date
和作为列表end_date
加载(这从未发生在我身上)。
当我尝试通过执行以下操作将列转换为日期时:
df %>%
mutate(start_date = as.Date(start_date))
我得到错误:
Error in as.Date.default(start_date) :
do not know how to convert 'start_date' to class “Date”
如何在保留日期列的同时正确导入它start_date
,end_date
以便对它们执行操作?
谢谢您的帮助。
