I have created a plot using the following command

ggplot(mdfr, aes(as.Date(value, "%d/%m/%Y"), name, colour = factor(stadio))) +
    geom_line(size = 5) +
    xlab("") + ylab("") + labs(colour="Title") +
    scale_colour_brewer(pal="RdYlGn",breaks = c("1", "2", "3","4"), labels = c("Label 1", "Label 2", "Label 3","Label 4"))

I need your help to do the following:

Change the size of the bars for the rows with names ending with an A. That is, instead of using geom_line(size = 5), I would like the size to be equal to the value of variable rating, i.e. 5 for names ending in B and 3 for names ending in A.
Is it possible to make the bars that have the same number in their name to look like pairs in order to look like having 11 pairs instead of 22 seperate ones? e.g. 737A to be closer to 737B than 734B. (so as and look like that chart).
In case a second (or third) legend appears, how can I suppress the appearance of a selected legend? – because using opts(legend.position = "none") makes all of them invisible.
Why does this ggplot command generates an error in ggplot 0.9.1 while it is ok if I use ggplot 0.8.9? (Error in scale_map.discrete(scale, df[[j]]) : attempt to apply non-function). How should I modify it?

Thanks in advance

EDIT

I found out the problem in No 4. Instead of pal=”RdYlGn” I should give palette=”RdYlGn”.

Edit, I had misread the first question

1) Use the rating with size as an aesthetic.

2) With the data you provided, the data is plotted that way but you can order it inside ggplot with order.

3) Use guide = none in the scale you want to remove.

ggplot(mdfr[order(mdfr$name),], aes(as.Date(value, "%d/%m/%Y"), name, colour = factor(stadio))) +
  geom_line(aes(size = as.factor(rating))) +
 labs(colour="Title", x = "", y = "") +
 scale_size_manual(breaks = c("3","5"), values = c(3,5), guide = "none")+
  scale_colour_brewer(palette="RdYlGn",breaks = c("1", "2", "3","4"), 
                      labels = c("Label 1", "Label 2", "Label 3","Label 4"))
