[R] sequentially aggregating elements of a vector

for labelling the stacked bars in a barplot, I need to sequentially sum up the elements of a vector.
Suppose I have;
x <- c(1,2,3,4)
(which correspond to the bar-width of stacked bars)
y <- c(1,3,6,11)
(which corresponds to the upper y-values for each bar).
What is the easiest way in R to get from x to y?
(Or more general; to add labels inside the bars in a stacked barplot)
