Mis primeros ejercicios

Graficas y funciones

En el siguiente caso analisamos gráficas y sentencias para facilitar el uso de R.

par(mfrow=c(2,3))
hist(rnorm(10,5.2,0.8),
     col=18,
     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=20,
     main="Histograma",
     xlab="rango",
     ylab="frecuencias")

hist(rnorm(100000,5.2,0.8),
     col=5,
     main="Histograma",
     xlab="rango",
     ylab="frecuencias")
hist(rnorm(1000000,5.2,0.8),
    col=12,
    main="Histograma",
    xlab="rango",
    ylab="frecuencias")

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.
