For "quick and dirty" I would suggest using Fisher's exact test on all
2x2 submatricies of counts. In this case, with 4 treatments you have
6 possible 2x2 submatrici
Dear Jason,
Convert Person to a factor with the levels in the order that you want.
Group_df$Person <- factor(Group_df$Person, levels = c("Them", "You", "Me"))

It appears that ggplot reorder the data for a "dodged" histogram based on
whether or not a specific variable has a value in the first bin.
I would like to be able to absolutely force the order of the variables in the
bin. For example, say I have three variables Me, You, and Them.
Me_df<-da
Can we give this a rest (or take it offline)? This is the R-Help
mail list, and I fail to grasp how anyone is being helped to use R by
this endless discussion.

I don't know about the maptools package but one general way to do this
would be to compute the convex hull (?chull) of the augmented set of
points and test if the point belongs to it.
Hope this helps,

Hi,
If you have a variable, that defines what you want to differentiate (sociology,
economics etc.) then you can add color depending on the value of that
variable. You will have to convert it to numeric if it is not.
An example would be
plot( iris[ , 1 ], iris[ , 2], col = iris[ , 3 ] )
Re
Did you want something like this:
library(lattice)
x <- plogis(.x, location=0, scale=1)
y <- plogis(.x, location=2, scale=4)
xvals <- seq(-7.6, 7.6, length=100)
xyplot(x+y ~ xvals, type = c("g", "l"))

I have been using the dse1 and dse2 packages to estimate a model in which the
underlying state is an ARMA(2,2) and the observed variables are equal to the
state plus noise. I am describing this model using a state space model.
First, in estimation, is there a way to restrict two of the estimate
I am doing some bibliometric analysis of interdisciplinarity using
cluster analysis of co-authorship.
I'd like to be able to specify the colour of individual authors in the
