如何从RMarkdown发布到Wordpress？

Question

我尝试使用knit2wp，当我在RStudio上单击Knit时，它显示的很好。但是，无论我使用knit2wp运行什么，它都会返回以下错误：

processing file: TestMark.rmd
|.................................................................| 100%
 ordinary text without R code

output file: TestMark.md

Entity 'raquo' not defined
Entity 'raquo' not defined
EntityRef: expecting ';'

xmlParseEntityRef: no name
xmlParseEntityRef: no name
EntityRef: expecting ';'
error parsing attribute name
attributes construct error
Couldn't find end of Start Tag j.length line 50
xmlParseEntityRef: no name

关于如何纠正此问题的任何想法？
