Changing a logical matrix into a numeric matrix
Hi,
I would like to turn my TRUE/FALSE matrix into a 1/0 matrix (i.e. True=1 and
False=0)
[,1] [,2] [,3]
[1,] TRUE FALSE FALSE
[2,] TRUE TRUE FALSE
[3,] TRUE TRUE TRUE
[,1] [,2] [,3]
[1,] 1 0 0
[2,] 1 1 0
[3,] 1 1 1
Is there a quick way of doing this without a loop?
Thanks Emma

more boa plots questions
I have MCMC output chains A and B for example, I want to produce trace plots

#plot trace plot
problems arise here!
I know I can get trace plots using boa.plot('trace') but this plots the
