Hi list,
I am writing several functions and running out variable names.  I am using
words such as "t", "c", "matrix" to keep the notation same as formulas I am
using.

For example I have,

unnormalized <- function(t, x, y){
    val <- rnorm(t, mean=x, var=y)
    return(val)
}

metropolis <- function(t, c, x, y){
    den1 <- unnormalized(t, mean=x, sd=y)
    den2 <- unnormalized(c, mean=x, sd=y)
    if(den1 < den2)
       return(a)
    else
       return(b)
}

for(i in 1: 100){
    matrix <- c()
    matrix[i] <- metroplis(1, 2, 3, 4)
}
Here, I reused letter "t" and "c", and the word "matrix".  Could this cause
any potential problems?

Thanks in advance,
Mike
