当我尝试编织我的.Rmd文件时，我得到一个错误。代码本身在文件中运行良好;错误只在我尝试编织时发生。

字符串
从本质上讲，它似乎遇到了一个特殊的字符，导致它退出，但它说它遇到的特殊字符并不存在。也就是说，不管Bibr怎么想，都没有错误的%符号。下面是有问题的行。

{r tidy=TRUE, tidy.opts=list(width.cutoff=68)}
all_2014 <- ggplot(bunc.SNAP_geq_Pov, aes(fill = percent_geq_pov)) + 
  geom_sf(color = "black", size = .5) +  
  theme_minimal() +
  scale_fill_viridis_c(option = "magma", direction = -1) + ggtitle("2014") +
  theme(plot.title = element_text(size = 8, face = "bold")) +
  # facet_wrap(~county) + 
  # Here, it will place them together to form the overall area but I can't delineate between county boundaries since this is on the tract level
  theme(
    panel.grid.major.x = element_blank(),  
    panel.grid.minor.x = element_blank(), 
    panel.grid.major.y = element_line(),

正如我所说的，.Rmd文件中的一切都运行得很好，没有错误;我只是在编织时遇到了这个问题。
