Evelyn Hall: I would like to know how (if) I can extract some of the
information from the summary of my nlme.
Simon Blomberg: This is R. There is no if. Only how.

df <- data.frame(matrix(rnorm(15), nrow = 3))
colnames(df) <- paste("species", 1:5, sep = "")
df$location <- paste("loc", 1:3)
install.packages("ggplot2")
library(ggplot2)
molten <- melt(df, id.vars = "location", variable_name = "species")
molten$sign <- factor(sign(molten$value))
ggplot(molten, aes(x = species, y = location, colour = sign, size =
abs(value))) + geom_point()

ggplot(molten, aes(x = species, y = location, colour = sign, size =
abs(value))) + geom_point() + scale_colour_manual(values = c("red",
"blue"))

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.
