Hi again all,
As the original code lines I had dated back to 2007 that may have
predated reshape2?
In any case the use of *dcast *rather than /*cast*/ solved the issue.
Then with 3 steps:
Stop
read
Think
I saw I just needed to change the line
input.cast <- cast(input.melt, Species ~ *Date*, fun.aggregate = sum)
to
input.cast <- cast(input.melt, Species ~ *Time*, fun.aggregate = sum)
...and it all works as expected and needed.
Thanks again all who replied.
