当knitr使用par mfcol参数有多个时，---

```{r}
set.seed(73856421)
# Plot random number of graphs
par(mfcol = c(2, 2))
for(i in 1:sample.int(6, 1)) # not in control of the number of plots here
plot(rnorm(100))
# <-- want plot here
# ...
# some other code
# ....
# plot new results
plot(1, type = "n", xlim = c(0, 1), ylim = c(0, 1))
text(.5, .5, "should be")
plot(1, type = "n", xlim = c(0, 1), ylim = c(0, 1))
text(.5, .5, "together")
plot(1, type = "n", xlim = c(0, 1), ylim = c(0, 1))
text(.5, .5, "in new")
plot(1, type = "n", xlim = c(0, 1), ylim = c(0, 1))
text(.5, .5, "4x4 plot")
```
是否有办法在代码块中完成绘图并开始新的绘图同一情节中的数字。我的代码大致类似于
# <-- want plot here问题在于，第一个4x4图未显示在plot.new，并且其中有两个下一个数字。到目前为止，我最好的解决方案是跟踪数字的数量，并使用frame或var defs = svg.append('defs');
defs.append("pattern")
.attr("x", 0)
.attr("y", 0)
.attr("id", "myPattern")//ID here
.attr("width", 12)
.attr("height", 12)
.append("image")
.attr("xlink:href", 'https://assets-cdn.github.com/images/modules/open_graph/github-octocat.png')
.attr("width", 12)
.attr("height", 12)
.attr("x", 0)
.attr("y", 0);
为＃34;缺少＆＃34;数据。虽然在我目前的设置中这比上述更复杂，但这是一个单调乏味的事情。
