This is a page I created in R Markdown and used knitr to produce the output to html. I then copied the html file into a new post and did some editing. I am using the data from the “airquality” data set already in R and I followed Rodger Peng’s directions on using knitr to create an html or Word file.
library(datasets)
data("airquality")
summary(airquality)## Ozone Solar.R Wind Temp ## Min. : 1.00 Min. : 7.0 Min. : 1.700 Min. :56.00 ## 1st Qu.: 18.00 1st Qu.:115.8 1st Qu.: 7.400 1st Qu.:72.00 ## Median : 31.50 Median :205.0 Median : 9.700 Median :79.00 ## Mean : 42.13 Mean :185.9 Mean : 9.958 Mean :77.88 ## 3rd Qu.: 63.25 3rd Qu.:258.8 3rd Qu.:11.500 3rd Qu.:85.00 ## Max. :168.00 Max. :334.0 Max. :20.700 Max. :97.00 ## NA's :37 NA's :7 ## Month Day ## Min. :5.000 Min. : 1.0 ## 1st Qu.:6.000 1st Qu.: 8.0 ## Median :7.000 Median :16.0 ## Mean :6.993 Mean :15.8 ## 3rd Qu.:8.000 3rd Qu.:23.0 ## Max. :9.000 Max. :31.0 ##
Here is a pairs plot.

Here is a regression model with the output below
fit=lm(Ozone~Solar.R + Wind+Temp, data=airquality) summary(fit)
