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:

ggplot(diamonds,aes(carat))+geom_histogram(binwidth = 0.1)

Including Plots

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.

ggplot(diamonds,aes(color))+geom_bar()

diamonds %>%
  arrange(desc(carat))%>%
  head(100)%>%
  select(carat,cut,color,price)   # DT::datatable()

# A tibble: 100 x 4
   carat       cut color price
