Error in plot.zoo() : "attempt to replicate an object of type 'closure'"

I was replicating codes from DataCamp on my laptop:

 library(xts) 
 plot.zoo(flights_xts, plot.type = "multiple", ylab = labels)
 plot.zoo(flights_xts, plot.type = "single", lty = lty)
 legend("right", lty = lty, legend = labels)

and was getting the following errors while executing the above three lines of code:

Error in rep(ylab, length.out = ngraph) : 
attempt to replicate an object of type 'closure'

Error in strwidth(legend, units = "user", cex = cex, font = text.font) : 
cannot coerce type 'closure' to vector of type 'character'

It looks like datacamp.com objects lty and labels are predefined for this task. For me works:

lty <- c(1, 2, 3, 4)
labels <- c("Total", "Delay", "Cancel", "Divert")

The error is fixed when quotes (".") are used in function parameters:

plot.zoo(flights_xts, plot.type = "multiple", ylab = "labels")
plot.zoo(flights_xts, plot.type = "single", lty = "lty")
legend("right", lty = "lty", legend = "labels")

It's still interesting though that in on-line DataCamp.com environment these quotes were not required. Any comments about that?
