Hi,
I have a vector in a data frame that looks
something like this:
day<-c('Day -1','Day 6','Day 10')
This vector specifies the order in which several
panel will appear in a lattice plots. But the order in
which such plots will appear will be the following:
Day -1, Day 10, Day 6. Which makes sense, but I cannot
name the Days like this: Day -01,Day 10, Day 06, which
would put the levels in the order I want them to be.
Now, this vector won't always have the same values,
it could be:
day<-c('Day -1, 'Day 2','Day 14')
So I cannot set the levels manually:
levels(day)<-c('Day -1', 'Day something','Day
something else')
I tried as.ordered, but I guess I am not using the
right function.
How can I command the script to put the panels in the
original order given of the vector in a data frame?
Thank you,
Judith
