Rsquared for anova
I calculate an anova test in the following way:
expdata<-read.table("/home/dorien/UA/meta-music/optimuse/optimuse1-build-desktop/results/results_processedCP",
header=TRUE)
names(expdata)<-c('nh1','nh2','nh3','randsize','aweights','tt1','tt2','tt3','path','iters','type','length','tos','tws','time')
fit<-(aov(tos~nh1*nh2*nh3*randsize*aweights*tt1*tt2*tt3*iters*length,
data=expdata))
summary(fit)

Plotting barplot and scatterplot on same device - x-axis problem
...-axis is not positioned equal for the
two plotting functions (see picture) and I have been unable to find out how
this is changed.

I have added the script if this is of interrest:
par(mar = c(7, 4, 4, 2) + 0.1)
barplot(rbind(data$Asn,data$Glu,data$NH3),
beside=T,
axes=TRUE,
xlim=c(0,57),
ylim=c(0,10))
par(new=TRUE)

selecting maximum values
Sorry for disturbing you with another newbie question!
I have a data frame about coastal waters quality
parameters: for some parameters (e.g. NH3) I have only
1 observation for each sampling station and each
sampling date, while in other cases (chlorophyll) I
have 1 obs for each meter-depth for each station and
date. How can I select only the max chlorophyll value
for each station/date?
example
row station date depth ch...

problem with library tseriesChaos
Hi R-Users
I need to estimate Lyapunov exponent of my time series. After reading
description of all functions available I still don't know how to determine
time delay. My time series length is 4200. Is it possible to determine time
delay with other function's output or I can choose any random value?
Thanks for your help!
