Yes, it can cause problems. And speaking for myself, I'd say it's not
worth the risk, because it's easy enough to find alternative variable
names that are close enough to the notation of your formulas that
remembering should be no problem. For example, "tt", "cc", and "mmatrix"
might do it.

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
