So that it look like this picture (or better with each line in a seperate plot) that I created with Excel.

But I can't figure out how...

Thanks a lot for your help. Dominik

UPDATE: Here is just a map of what the groups (BUM,DDR,ETB etc.) mean.

Answer 1

This is an extension to @Andrie's solution. It combines the faceting idea with that of overplotting (stolen liberally from the learnr blog, which I find results in a cool visualization. Here is the code and the resulting output. Comments are welcome

mdf <- melt(df, id.vars="X")
mdf = transform(mdf, variable = reorder(variable, value, mean), Y = X)

ggplot(mdf, aes(x = variable, y = value)) + 
  geom_line(data = transform(mdf, X = NULL), aes(group = Y), colour = "grey80") +
  geom_line(aes(group = X)) +
  facet_wrap(~X) +
  opts(axis.text.x = theme_text(angle=90, hjust=1))

EDIT: If you have groupings of milieus, then a better way to present might be the following

mycols = c(brewer.pal(4, 'Oranges'), brewer.pal(4, 'Greens'), 
           brewer.pal(3, 'Blues'), brewer.pal(3, 'PuRd'))
mdf2 = read.table(textConnection("
  V1,  V2
  ETB, LEIT
  PMA, LEIT
  PER, LEIT
  LEIT, LEIT
  KON, TRADITION
  TRA, TRADITION
  DDR, TRADITION
  TRADITION, TRADITION
  BUM, MAIN
  MAT, MAIN
  MAIN, MAIN
  EXP, HEDOS
  HED, HEDOS
  HEDOS, HEDOS"), sep = ",", header = T, stringsAsFactors = F)

mdf2 = data.frame(mdf2, mycols = mycols)
mdf3 = merge(mdf, mdf2, by.x = 'X', by.y = "V1")

p1 = ggplot(mdf3, aes(x = variable, y = value, group = X, colour = mycols)) + 
  geom_line(subset = .(nchar(as.character(X)) == 3)) +
  geom_line(subset = .(nchar(as.character(X)) != 3), size = 1.5) +
  facet_wrap(~ V2) +
  scale_color_identity(name = 'Milieus', breaks = mdf2$mycols, labels = mdf2$V1) +
  theme_bw() + 
  opts(axis.text.x = theme_text(angle=90, hjust=1))
