[R] order in stacked barplot

[John Kane]

Could be few things but we probably need some sample data to get a feeling for what you are doing.

 The easiest way to supply data  is to use the dput() function.  Example with your file named "testfile": 
dput(testfile) 
Then copy the output and paste into your email.  For large data sets, you can just supply a representative sample.  Usually, 
dput(head(testfile, 100)) will be sufficient.
