This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.
When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
代码语言：{r cars}复制summary(cars)Including Plots
You can also embed plots, for example:
代码语言：{r pressure, echo=FALSE}复制plot(pressure)Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
