我正在使用pgfsweave与Lyx 1.6.8和xtable.提供表格标题

<<result=tex>>=
print(xtable(<dataframe>,caption="Here is my caption"))
@.

如何在表格标题中插入标签,我可以在lyx>插入>交叉引用菜单的文本中进行交叉引用？

我试图插入>浮>表和插入 print(xtable(<dataframe>,floating=FALSE))并 "Here is my caption"在表标题内框架但是这导致(字面意思):

[?oat Table:
<...Table ...>
[Table 2: "Here is my caption" ] ]

甚至是赤脚的交叉引用解决方法

<<result=tex>>=
print(xtable(<dataframe>,caption="Here is my caption",label = "tab:one"))

来自ERT-box会有所帮助.

我在 *.Rnw.log 中遇到以下错误：

Error:  chunk 3 (label=printgraph) 
Error in grid.Call.graphics("L_text", as.graphicsAnnot(x$label), x$x,  : 
  Metric information not available for this family/device 

仅在 Lyx 中并取决于声明

+ scale_y_log10(ylim=c(0.025,5)) 

在以下示例代码中：

<<Code, tidy=T, sanitize=TRUE>>= 
require(ggplot2)
df.qdf=data.frame(T     =     c(0    ,1,2  ,0    ,1.5,2.5)
                 ,q.500 =     c(0.025,2,1  ,0.025,  4,2  )
                 ,q.025 = 0.5*c(0.025,2,1  ,0.025,  4,2  )
                 ,q.975 = 1.5*c(0.025,2,1  ,0.025,  4,2  )
                 ,Occasion  = c(    1,1,1  ,2    ,  2,2  )
                 )
theme_set(theme_bw())
Graph=(qplot(T,q.500,data=df.qdf) 
      +geom_smooth(aes(ymin=q.025,ymax=q.975)
                  ,data=df.qdf
                  ,stat='identity'
                  ,fill='blue') 
      +ylab('Response')
      +xlab('Time [h]')
      +facet_grid(facet=.~Occasion)
      ) +scale_y_log10(ylim=c(0.025,5))

<<printgraph,echo=FALSE,fig=TRUE,width=10,height=7,sanitize=TRUE>>=
print(Graph)
