[R-sig-Geo] line segments and stripcharts to plot range.

[Dennis Murphy]

Hi:

This is actually not too hard to do in ggplot2 using the linerange
geom. Using your data frame hummers (I love those little guys :),

library('ggplot2')
ggplot(hummers, aes(x = Eng)) +
    geom_linerange(aes(ymin = Min, ymax = Max), colour = 'red', size = 1.5) +
    labs(x = '', y = 'Elevation (ft)') +
    coord_flip()

HTH,
Dennis
