mfrow and centering plots when there's an odd number
Let me start with an example:
par(mfrow=c(2,3))
for (i in 1:5){
x = rnorm(100)
y = .5*x + rnorm(100, 0, sqrt(1-.5^2))
plot(x,y)
}
Note that there's five plots and six spaces for those plots via mfrow,
leaving one row empty. Is there a way to have the bottom two plots
centered? I think it looks weird to have them left-justified. Thanks in
advance for the help!

Long lines with Sweave
I have used Sweave a lot the latest year, but never really used any long
function calls.
If I have code which look like this
-------------------------------------------------------------
gof <- benthic.flux(ID="Gulf of Finland",
meas.conc=conc,
bw.conc=bw.conc,
time=times,
substance=expression(DIC~(mmol~m^{-3}))
)
-------------------------------------------------------------
I get t...

plotting multiple variables in 1 bar graph
...greatly appreciate your help in making a bar graph with multiple
variables plotted on it. All the help sites I've seen so far only plot 1
variable on the y-axis
Data set:
I have 6 sites, each measured 5 times over the past year. During each
sampling time, I counted the occurrences of different benthic components
(coral, dead coral, sand, etc.) over 5 transects in each site

any DCCA function in R?
Dear members,
I am performing multivariate analysis on marine benthic populations
using R. At first glance I found ca and VEGANO packages to be the
suitable for the task, but neither has incorporated Detrended Canonical
Correspondence Analysis (DCCA), which is just the method I want to apply
on my data. I've looked for alternative packages containing the meth...

Array as time series?
Dear R-helpers,
I have 4-dimensional atmospheric data (x,y,z,t), which I want to analyse
on spatio-temporal diversities.
As far as I understand there only exists the possibility to construct
time series as two-dimensional matrices (mts).
For the moment, I hold it in different objects:
1. a four-dimensional array for the spatial related analyses
2. a two-dimensional mts timeserie, which was
