 # FUNCTIONS
 
 # Defined like so:
-myFunc <- function(x) {
-	x <- x * 4
-	x <- x - 1
+jiggle <- function(x) {
+	x+ rnorm(x, sd=.1)	#add in a bit of (controlled) noise
 	return(x)
 }
 
 # Called like any other R function:
-myFunc(5)	# 19
+jiggle(5)	# 5±ε. After set.seed(2716057), jiggle(5)==5.005043
