Dear Wiza[R]ds,
I have the following data in a data.frame. I need to do an anova with
multiple comparison but I don't know how to factor the groups for analysis.
There are 3 groups, 1,2 and 3 labelled in column 1. Help appreciated with

help with aggregate()
Hi,
I am trying to aggregate some data and I am confused by the results.
I load a data frame "all" from a csv file, and then I do:
(FOO,BAR,X,Y come from the header line in the csv file,
BTW, how do I rename a column?)
byFOO <- aggregate(list(all$BAR,all$QUUX,all$X/all$Y),
by = list(FOO=all$FOO),
FUN = mean);
I expect a data frame with 4

outlining (highlighting) pixels in ggplot2
Using the small reproducible example below, I'd like to know if one can
somehow use the matrix "sig" (defined below) to add a black outline (with
lwd=2) to all pixels with a corresponding value of 1 in the matrix 'sig'?
So for example, in the ggplot2 plot below, the pixel located at [1,3] would
be outlined by a black square since the value at sig[1,3] == 1. This is my
first

outlining (highlighting) pixels in ggplot2
Hi Eric,
you can use an annotate-layer, eg
ind<-which(sig>0,arr.ind = T)
ggplot(m1.melted, aes(x = Month, y = Site, fill = Concentration), autoscale
= FALSE, zmin = -1 * zmax1, zmax = zmax1) +
geom_tile() +
coord_equal() +
scale_fill_gradient2(low = "darkred",
mid = "white",
high = "darkblue",

split plot design with missing plots
Windows 2000 . 5.00.2195 with Service Pack 1.
R 1.5.1
Output from my split-split plot aov "alerted" me that I have done something
wrong. I designed an experiment with all combinations of all levels of each
treatment, but lost a little data (3 out of 192 plots). With the following
data, I run the following model:
> collim[c(1:6,187:192),c(1,3:6,9)]

post hoc in repeated measures of anova
Hallo, I have this dataset with repeated measures. There are two
within-subject factors, "formant" (2 levels: 1 and 2) and "f2 Ref" (25
levels: 670, 729, 788, 846, 905, 1080, 1100, 1120, 1140, 1170, 1480,

2120, 2040, 1950), and one between-subject factor, lang (2 levels:1
and 2). The response variable
