[R] problem with parameters

[Joshua Wiley]

Well since you said that it cannot recognize the value of 'p', this
suggests that you have not defined that object.  Here is an example of
what you might be trying to do (you can just copy and paste the code
into R):

########################################
## create x matrix of 0s
x <- matrix(0, nrow = 21, ncol = 21)
## define 'p'
p <- runif(1)
## assign 'p' to row 1 column 1
x[1, 1] <- p
## assign '1 - p' to row 10, column 10
x[10, 10] <- 1 - p
## print matrix
x
########################################
