将CSV读入R，但得到0个观察结果

Question

我有看起来像这样的数据，下面是记事本的屏幕截图。

但是，当我运行以下代码以将其读入R时，我得到了。

pdata = read_csv('kd30.csv') 

我认为这与“ 12中的土壤湿度”有关，因为当我手动将名称更改为soil12时，它会读入。但是我需要它用于给定的列名，因为我有很多需要读入这样的数据。

这里是纯文本格式数据的示例

,12" Soil Moisture (%VWC),16" Soil Moisture (%VWC),20" Soil Moisture (%VWC),Pressure Switch (on|off)

Answer 1

您可以跳过第一行，并为列名提供col_names的read_csv参数：

read_csv('kd30.csv', col_names = c("soil_moisture_12_inch", "soil_moisture_16_inch", "soil_moisture_20_inch", "pressure_switch"), skip = 1)

Answer 2

根据RFC4108，这是无效的csv文件。

如果字段没有用双引号引起来，则双引号可能不会出现在字段内。

我建议您修复文件或在阅读文件时跳过文件的第一行。
