[R] Plotting from a list

[Gabor Grothendieck]

Convert it to long form and plot like this (or look at ggplot2 for
another approach):

DF <- structure(list(A = c(8.423645, 30.881773, 29.783251, 17.827586,
27.507389, 17.46798, 8.167488, 32.502463, 44.610837), B = c(0.208,
27.344, 15.824, 31.776, 30.52, 27.232, 0, 19.736, 11.208), C = c(1.6296296,
13.2592593, 24.3333333, 14.7777778, 12.2222222, 34.2592593, 1.4074074,
34.6666667, 1.7777778), D = c(0, 26.2962963, 26.3333333, 23.8888889,
30.8518519, 42.4074074, 0, 39.8888889, 15.6296296), E = c(0,
22.3090909, 19.5090909, 25.2, 25.8363636, 45, 0, 28.5272727,
17.8545455), F = c(0, 22.4545455, 34.4545455, 21.7272727, 13.7272727,
34.0909091, 0, 43.6363636, 7.5454545)), .Names = c("A", "B",
"C", "D", "E", "F"), class = "data.frame", row.names = c("1965",
"1966", "1967", "1968", "1969", "1970", "1971", "1972", "2000"
))

library(lattice)
long <- as.data.frame.table(as.matrix(DF), responseName = "Pop")
barchart(Pop ~ Var2 | Var1, long)
