[R] Changing legend to fill colour in ggplot

[John Kane]

While the str() data is useful it is much better to provide real sample data.  Use dput() to supply it.

 If it is a large file send a sample head(dput(df, "somenumber)) with somenumber just enough to provide a representative sample.

We currrently have no idea of what the graph looks like as the R-help list strips that out .With the actual data a reader can just copy it and your code into R and see exactly what you are getting.

Please don't post in HTML. Plain text is much easier to read, the HTML gets dropped and any formating goes to pot.

I think the actual answer is probably straight forward but we really should have the data

Thanks
