Question

这是我的代码。我有一个包含多个工作表的xlsx文件，我正在尝试加载第一个工作表。

我使用RStudio Excel IDE加载工作表

它生成了以下代码，但它将所有属性视为字符，但它应该将第一个和第四个标识为数字，因此我在导入之前手动更改了它。

> PharmacyMaster <- read_excel("~/Desktop/R/ABDataSet(WithDataSetMaster).xlsx", 
+     sheet = "PHRMCY MASTER", col_types = c("numeric", 
+         "text", "text", "numeric"))

数据集已导入，但我收到50条警告，我不确定它们是指什么。

There were 50 or more warnings (use warnings() to see the first 50)
> View(PharmacyMaster)
> warnings()
Warning messages:
1: In read_fun(path = path, sheet = sheet, limits = limits,  ... :
  Coercing text to numeric in A2 / R2C1: '1017330163607345979'
2: In read_fun(path = path, sheet = sheet, limits = limits,  ... :
  Coercing text to numeric in D2 / R2C4: '070'
3: In read_fun(path = path, sheet = sheet, limits = limits,  ... :

5: In read_fun(path = path, sheet = sheet, limits = limits,  ... :

我已检查加载数据集的结构

> str(PharmacyMaster)
Classes ‘tbl_df’, ‘tbl’ and 'data.frame':   1097 obs. of  4 variables:
 $ PHRMCY_NBR: num  1.02e+18 1.04e+18 1.05e+18 1.06e+18 1.06e+18 ...
 $ PHRMCY_NAM: chr  "GNP PHARMACY #1" "GNP PHARMACY #2" "GNP PHARMACY #3" "GNP PHARMACY #4" ...
 $ ST_CD     : chr  "NJ" "NJ" "MA" "NJ" ...
 $ ZIP_3_CD  : num  70 71 21 70 100 11 70 193 75 70 ...

我有两个问题， 1.为什么readxl无法识别数字列并加载为数字，您可以从我手动更改的IDE屏幕截图中看到。（可以在下面找到数据集的快照） 2.警告意味着什么？

P.S。数据集的数字列中没有引用值或空值，我已手动检查了所有1097行。

Readxl函数无法检测数据类型并在强制加载后发出警告
