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:

Warning: 程辑包’tidyverse’是用R版本4.1.3 来建造的

– Attaching packages ————————————— tidyverse 1.3.1 –

v ggplot2 3.3.6 v purrr 0.3.4

v tibble 3.1.6 v dplyr 1.0.9

v tidyr 1.2.0 v stringr 1.4.0

v readr 2.1.2 v forcats 0.5.1

Warning: 程辑包’dplyr’是用R版本4.1.3 来建造的

– Conflicts —————————————— tidyverse_conflicts() –

x dplyr::filter() masks stats::filter()

x dplyr::lag() masks stats::lag()

```

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