Diagramas de Barras de Ernesto

Vamos a utilizar la función barplot() y los paquetes gpplot2 y lattice.

EJERCICIOS ADICIONALES CON mtcars:

#mtcars
tabla.1 <- table( mtcars$cyl )
#tabla.1

colores <- c( "orange" , 
              "green" , 
              "yellow" )
#colores

plot.1 <- barplot( tabla.1 , 
                   xlab = "Cilindros" , 
                   ylab = "Frequencia" , 
                   main = "Nro de Cilindros" ,
                   col = colores )

plot.1
##      [,1]
## [1,]  0.7
## [2,]  1.9
## [3,]  3.1

Con library lattice:

library(lattice)
#mtcars
tabla.1 <- table( mtcars$cyl )
#tabla.1

colores <- c( "orange" , 
              "green" , 
              "yellow" )
#colores

plot.3 <- barchart( tabla.1 , 
                    xlab = "Cilindros" , 
                    ylab = "Número de Cilindros" , 
                    main = "Número de Cilindros", 
                    col = colores )

plot.3

CONTINUACION CON mtcars :

library(ggplot2)
plot.2 <- ggplot( mtcars ,
                  aes( cyl )) +
          geom_bar( fill = colores ) + 
          labs( x= "Cilindros" , 
                y = "Frecuencias" , 
                title = "Numero de Cilindros")
plot.2

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:

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