When I try to run this code:

l2 <- sapply(l1, function(x) { ## no livro código é "sapply(l1, function(x) {"
nr <- nrow(x)
x$bubble <- numeric(nr)
x$bubble[1] <- x$gate[1] ## start somewhere
for (i in 2:nr) {
x$bubble[i] <- x$gate[i] +
as.numeric(x$gate[i] >= x$bubble[i-1])
#se mudou de porta, mudou de bubble também
}
x
},
simplify = FALSE)

RStudio shows this error:
Error in numeric(nr) : invalid 'length' argument

I think the list should be used is "l1", rather than "l".
