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

You can also embed plots, for example:

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

library(lattice)#绘图包
airquality$Month<-factor(airquality$Month)
xyplot(Temp~Ozone|Month,data = airquality,layout=c(5,1))#附加条件，就是在不同的月份下的温度与二氧化碳的情况，所以值得重视，layout是一个布局参数，五行一列

ggstatsplot::ggscatterstats(
  data = ggplot2::msleep,
  x = sleep_rem,
  y = awake,
  xlab = "REM sleep (in hours)",
  ylab = "Amount of time spent awake (in hours)",
  title = "Understanding mammalian sleep",
  messages = FALSE
)

###注意：1、点之间才能写代码，会识别，直接在r的花括号中echo=-将代码隐藏掉了。然后在花括号之外可以直接谢代码了。2、最好是在R上写完之后把他转移过来。3、同级标题间要隔开一行，但是不同级之间直接挨着就可以，注意有序和无序之间的区别!！直接打字会显示，三个星号，又斜又粗）
