Error in 7 % % 2 : could not find function "% %"
时间: 2024-01-23 12:35:03 浏览: 21
抱歉,我之前给出的回答中有错误。在R语言中,"%%" 运算符用于模运算(取余),而不是 "% %" 运算符。因此,7 % % 2 是无效的表达式,会导致错误。正确的表达式应该是 7 %% 2。
以下是正确的示例代码:
```R
result <- 7 %% 2
print(result)
```
以上代码将输出结果为 1,因为 7 除以 2 的余数为 1。再次对之前的错误表示抱歉,并感谢您的纠正!

Error in t(I) %∗% solve(V) %∗% e : could not find function "%∗%"
The error message indicates that the function "%*%" is not recognized by R. This could be due to a typographical error or because the function is not loaded in your R session.
In R, the symbol "%*%" is used for matrix multiplication. If you are trying to perform matrix multiplication, you can use the symbol "%*%" instead of "%∗%".
If you are trying to use a custom function that uses "%∗%" for matrix multiplication, you may need to define the function or load the package that contains the function before using it.
Error in mydata %>% tbl_summary() : could not find function "%>%"
这个错误通常是因为你没有加载 `dplyr` 库。`%>%` 是 `dplyr` 库中的一个非常有用的符号,它被称为“管道操作符”,可以使代码更加简洁和易读。请尝试在运行代码之前加载 `dplyr` 库,可以使用如下代码加载:
```R
library(dplyr)
```
或者在使用 `%>%` 之前,加上 `dplyr::` 前缀,如下所示:
```R
mydata %>% dplyr::tbl_summary()
```
