我正在尝试使用以下代码在R中读取一个简单的csv文件：

data <- read.csv(file="\0Laplacian1Entropy.csv", header=TRUE, sep=" ")

但我总是得到这个错误：

> Error: embedded nul in string: '\0Laplacian1Entropy.csv'

这是我的文件：

i j Entropy

这与您的 csv 文件无关。错误消息指出您在文件名中嵌入了一个 nul 字符：\0表示ASCII 字节 == 0，这在 R 字符串中是禁止的（在内部，它表示字符串的结尾）。

也许你的意思是"\\0Laplacian1Entropy.csv"或"/0Laplacian1Entropy.csv"。无论如何，如果您希望在字符串中包含反斜杠，则必须使用...反斜杠对其进行转义。

删除 de "\0" 并让您的命令像这样：

数据 <- read.csv(file="Laplacian1Entropy.csv", header=TRUE, sep="")
