[R] barplot beside=TRUE - values differ on scales

[Adams, Jean]

Adrian,

What story are you trying to tell?  Or what question are you trying to
answer by visualizing these data?  How is a bar plot of these numbers going
to help?  I'm just wondering if perhaps a different visualization might
make more sense, for example, a scatter plot of GN vs. CN.

m <- structure(c(112L, 0L, 579L, 1L, 131L, 1L, 2234L, 2L, 2892L, 1L,
  528L, 0L, 582L, 2L), .Dim = c(2L, 7L), .Dimnames = list(c("GN",
  "CN"), c("DC5", "DC8", "DC14", "DC18", "DC19", "DC20", "DC23"
  )))
plot(m["GN", ], m["CN", ])

Jean
