R Markdown

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:

summary(cars)

##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

plot of chunk pressure

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

设置

在knitr::opts_chunk$set(echo = TRUE,message = F,warning = F)中添加message = F,warning = F代码，以让一些没用的提示信息和警告的信息不需要展示在Rmarkdown输出结果中

标题

两个#号表示这是一个二级标题，# 号和后面的内容之间有一个空格

#直接在markdown中书写代码块的方法为在英文输入法状态下按三下1前面的破折号后按回车,在R Markdown中，使Ctrl+ALT+I插入。
