Thanks for all the suggestions, but it seems, that all these functions need a rearrangement of my data, since in my case, the dependent variables are in different columns. The error.bars.by-function seems to be the only plotting function, that does not need a rearrangement. Are there other functions, which can do that or is there an easy way to rearrange the columns into one?
