尝试使用RWordPress将Rmd文件上传到WordPress时出现模糊错误

Question

我正在尝试将Rmd文件作为RWordPress的帖子上传到WordPress网站。当我遵循this blog时，我会转到使用

的部分

knit2wp("question2.Rmd", title = "This is a new test", publish = FALSE)

，我收到以下32个错误。无论使用什么文件，总会有32个错误。它们也总是相同的顺序。

这是我正在使用的文件question2.Rmd。 （R降价和堆栈溢出之间存在冲突，我是两者的新手，所以我为它看起来很笨而道歉）

## Question

ranData <- round(runif(2,2,20))

ans <- ranData

Solve the following quadratic equation. \[x^2 + `r ranData[1] + ranData[2]`x + `r ranData[1]*ranData[2]` = 0 \]

## Answer

The solutions are $x = `r ans[1]`$ and $x = `r ans[2]`$.
