根据你提供的代码和错误信息,看起来像是在读取csv文件时出现了问题。可能是因为文件中的某些行或列有非数字的字符,导致无法将其转换为数字类型。你可以尝试使用以下代码来排除这个问题:
```
speed <- read.table("C:/Users/郭恒辰/Desktop/数据补充/使用lmm线性混合模型/语速.csv", header = TRUE, sep = ",", colClasses = c("character", "numeric", "numeric"), stringsAsFactors = FALSE, check.names = FALSE, na.strings = "N")
```
在这个代码中,我们添加了一个新的参数`na.strings = "N"`,它会将所有"N"字符视为缺失值,避免了无法转换为数字类型的错误。希望这可以解决你的问题。

> speed <- read.table("C:/Users/郭恒辰/Desktop/数据补充/使用lmm线性混合模型/语速.csv", header = TRUE, sep = ",", colClasses = c("character", "numeric", "numeric"), stringsAsFactors = FALSE)speed$Subject <- as.factor(speed$Subject) Error: unexpected symbol in "speed <- read.table("C:/Users/郭恒辰/Desktop/数据补充/使用lmm线性混合模型/语速.csv", header = TRUE, sep = ",", colClasses = c("character", "numeric", "numeric"), stringsAsFact"
这个错误提示是因为你在输入代码时,将代码分成了两行,导致语法错误。你需要将两行代码合并成一行,或者使用换行符`\`将代码连接起来。例如:
```
speed <- read.table("C:/Users/郭恒辰/Desktop/数据补充/使用lmm线性混合模型/语速.csv", header = TRUE, sep = ",", colClasses = c("character", "numeric", "numeric"), stringsAsFactors = FALSE)
speed$Subject <- as.factor(speed$Subject)
```
需要修改为:
```
speed <- read.table("C:/Users/郭恒辰/Desktop/数据补充/使用lmm线性混合模型/语速.csv", header = TRUE, sep = ",", colClasses = c("character", "numeric", "numeric"), stringsAsFactors = FALSE); speed$Subject <- as.factor(speed$Subject)
```
或者将两行代码用`\`连接起来,如下所示:
```
speed <- read.table("C:/Users/郭恒辰/Desktop/数据补充/使用lmm线性混合模型/语速.csv", header = TRUE, sep = ",", colClasses = c("character", "numeric", "numeric"), stringsAsFactors = FALSE) \
; speed$Subject <- as.factor(speed$Subject)
```
这样就可以顺利运行代码了。
Error: unexpected input in "speed <- read.table("C:/Users/郭恒辰/Desktop/数据补充/使用lmm线性混合模型/语速.csv", header=TRUE, sep=",", colClasses=c(“"
这个错误提示是因为在 colClasses 参数中使用了英文双引号的“”而不是英文半角双引号"",导致 R 无法正确解析该参数。请尝试修改该行代码如下:
```
speed <- read.table("C:/Users/郭恒辰/Desktop/数据补充/使用lmm线性混合模型/语速.csv", header=TRUE, sep=",", colClasses=c("factor", "numeric", "numeric"))
```
将中文引号改为英文半角双引号即可。
