transforming factor back to numbers
Hi
I generate a new dataframe by doing:
npl.agg <- aggregate(npl$DensPlants, list(year=npl$year, sim=npl$sim),
mean, na.rm=TRUE )
Now I want to plot it by using
coplot(npl.agg$x ~ npl.agg$year | npl.agg$sim, type="l")
but, as npl.agg$year is seen as a factor, the order of the points on the
x-axis (time axis) does not follow the numerical sorting 1...100, but
rather the text

I can do this like so:
binarize(dataframe[,-1])
this will return a dataframe, but then I lose my first column class, so I thought I could combine it like so:
dataframe <-
