Hi, 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) I need; 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) thanks!
Hello, Try ?cumsum cumsum(1:4) [1] 1 3 6 10 Hope this helps, Rui Barradas Em 14-10-2013 19:49, Martin Batholdy escreveu:> Hi, > > 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) > > I need; > > 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) > > > > thanks! > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >
> The last element 11 in y is confusing.sorry for the typo. It is of course y <- c(1,3,6,10)> cumsum(x)thanks!
