R - box design-scatter plot für means/regression/lme?
...t 3 time point: 0, 6 and 12 days after set up.
So I have now following Data:
Giraffe dung: wet/ dry treatment under shadow/sun condition, 3 collection times, always 5 Replikate
Same for the Wildebeest dung.
For the pellets I measured following variables:
DW.P = dry weight pro pellet
WL= water loss
Ctot= total carbon
Ntot=total nitrogen
Now, for my statistics I used:
lme(Y ~ Day*water.T*shadow.T*dung.T, random=~Day|Box/Pot)
but apperently I have to fit a linear correlation for Day, so that Day is not seen as a Factor.. How have I to do that?
Something Day <- corr(Day*Y)?
Then I also have to...

Enquiry regarding Apply

## Compute row and column sums for a matrix:
x <- cbind(x1 = 3, x2 = c(4:1, 2:5))
dimnames(x)[[1]] <- letters[1:8]
apply(x, 2, mean, trim = .2)
col.sums <- apply(x, 2, sum)
row.sums <- apply(x, 1, sum)
rbind(cbind(x, Rtot = row.sums), Ctot = c(col.sums, sum(col.sums)))
My questions are:
1. I don't understand what values I would need to enter for my 2 variables
(data is included at end of this message) in the 'cbind' command
2. For the second row, what modification is required?
3. If I wanted to compute a mean, I believ...
