Load the Data

red <- read.csv(‘winequality_red.csv’) white <- read.csv(‘winequality_white.csv’)

red[‘color’] <- ‘red’ white[‘color’] <- ‘white’

wine <- rbind(red, white) ## Including Plots

head(wine)

You can also embed plots, for example:

{r pressure, echo=FALSE} plot(pressure)

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