I got some error when I try to knit a ggplot object in a RMarkdown file.
The HTML output show only the graph grid without data and the warning rised is:
Warning in grid.Call.graphics(C_path, x$x, x$y, index, switch(x$rule, winding =
## 1L, : Path drawing not available for this device
Worth to notice that the same code in console show the desired output.
Any idea?
