默认情况下不适合幻灯片,甚至无法通过任何其他方式打印。
这是 .Rmd:编辑:看来您必须在每个块中使用 plot() 。现在打印第二个情节。
# Plot should show at high resolution
```{r echo=FALSE, comment = ""}
# load some data
require(plyr)
rbi <- ddply(baseball, .(year), summarise,
mean_rbi = mean(rbi, na.rm = TRUE))
```
```{r}
# plot
plot(mean_rbi ~ year, type = "l", data = rbi)
```
# Second attempt
```{r, fig.width = 2, fig.height = 2}
plot(mean_rbi ~ year, type = "l", data = rbi)
```
# Third attempt
```{r, out.width = 2, out.height = 2}
plot(mean_rbi ~ year, type = "l", data = rbi)
```
# Fourth attempt
```{r, out.width = '200px', out.height = '200px'}
plot(mean_rbi ~ year, type = "l", data = rbi)
```
# Fifth attempt
```{r, out.width = '\\maxwidth'}
plot(mean_rbi ~ year, type = "l", data = rbi)
```
将其另存为test.Rmd
然后使用 beamer 编译为 tex:
knit("test.Rmd")
system("pandoc -s -t beamer --slide-level 1 test.md -o test.tex")
在 RStudio 中打开test.tex
并单击“编译 PDF”。
我已经阅读了 Yihui 的文档,希望我没有错过一些非常明显的东西。
编辑包含 Yihui 建议的新代码。
```{r setup, include=FALSE}
opts_chunk$set(dev = 'pdf')
```
# Plot should show at high resolution
```{r echo=FALSE, comment = ""}
# load some data
require(plyr)
rbi <- ddply(baseball, .(year), summarise,
mean_rbi = mean(rbi, na.rm = TRUE))
```
```{r}
# plot
plot(mean_rbi ~ year, type = "l", data = rbi)
```
# Second attempt
```{r, fig.width = 4, fig.height = 4}
plot(mean_rbi ~ year, type = "l", data = rbi)
```
