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:

##puedo poner el nombre que yo quiera al chunk siguiente, sin usar espacios##

# Load the dataset to session with read.table command:
irisdata <- read.table("iris/iris.data", sep = ",")

str(irisdata)

graficando con ggplot2

library(ggplot2)
ggplot(data = irisdata, aes(Sepal.Length, Sepal.Width, color = Species)) +
    geom_point(size = 3)

Including Plots

##se pueden incrustar códigos para graficar##

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.
