Mis primeros pasos de R

Graficas y funciones

En el siguiente caso analizamos graficas y sentencias para facilitar el uso del R.

par(mfrow = c(2,3))

hist(rnorm(10,5.2,0.8),
     col = 2, 
     main = "histograma",
     xlab = "rango",
     ylab= "frecuencias")

hist(rnorm(100,5.2,0.8),
     col = 3, 
     main = "histograma",
     xlab = "rango",
     ylab= "frecuencias")

hist(rnorm(1000,5.2,0.8),
     col = 4, 
     main = "histograma",
     xlab = "rango",
     ylab= "frecuencias")

hist(rnorm(10000,5.2,0.8),
     col = 5, 
     main = "histograma",
     xlab = "rango",
     ylab= "frecuencias")

hist(rnorm(100000,5.2,0.8),
     col = 6, 
     main = "histograma",
     xlab = "rango",
     ylab= "frecuencias")

hist(rnorm(1000000,5.2,0.8),
     col = 7, 
     main = "histograma",
     xlab = "rango",
     ylab= "frecuencias")

summary(cars)

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.
