Add Anova statistics in each figure
Hi R Users,
I created interaction plots in ggplot2 and was trying to add output of two way ANOVA models, especially only interaction ( example treatment*control F(XX, XX) = xxx, p = xxx) into figures, but i was not able to add. Would you mind to help on how I can add information into each figure? I have attached the example data and the code that I used for this.

text(x,y,greek character)
Dear list,
I would like to plot points with two types of labels, one at the data
point (the name of the point) and another offset a bit with another
factor which is either of the two greek characters alpha or beta. I have
tried to get the routine to plot a greek character with expression() or
with substitute() and have not yet had any success. The following only
plots the word in english in

Contour plot
Hi, I would like to make a contour plot with the data below, x-axis= Day
(increasing order, day number is out of 365 days of a year), y-axis= Depth
(varies), and z=pH. I tried to use filled.contour function, but not sure the
proper way to ordinate my z results into a matrix with different x and y
length. After that, if I attempted to plot the data, the x and y values are
not in ascending

Contour plot- repost message
Hi, I would like to make a contour plot using R with the following information (data at the end): x-axis= arranged according to day (from 1 to 365, labels= use months; up to 365 days in one year), y-axis= depth (labels from 0 at the top to 7 at the bottom; this is a water depth profile), and z-axis= pH. So, this would be a pH contour plot of different dates throughout a year, with pH measured at

NA's in segmented
I am trying to fit a very simple broken stick model using the package
"segmented" but I have hit a roadblock.
> str(data)
'data.frame': 18 obs. of 2 variables:
$ Bin : num 0.25 0.75 1.25 1.75 2.25 2.75 3.25 3.75 4.25 4.75 ...
$ LnFREQ: num 5.06 4.23 3.50 3.47 2.83 ...
I fit the lm easily:
> fit.lm<-lm(LnFREQ~Bin, data=id07)
But I keep getting an error

using lapply()
useR's,
I am trying to find a quick way to change some values in a list that are
subject to a condition to be NA. Consider the 3x1 matrix:

And consider the list named v that has 3 elements

v[[1]]

means over factors in mlm terms
I'm trying to write a function to find the means over factors of the
responses in a mlm (something I would do easily in SAS with PROC SUMMARY).
The not-working stub of a function to do what I want is below,
and my problem is that I don't know how to call aggregate (or
some other function) in the context of terms in a linear model
extracted from a lm/mlm object.

distance matrix and hclustering

Puzzled at lm() and time-series
I tried toy problems and there doesn't seem to be a basic problem
between lm() and ts objects:
X = data.frame(x=c(1,2,7,9), y=c(7,2,3,1))
lm(y ~ x, X)
X <- lapply(X, function(x) ts(x, frequency=12, start=c(1994,7)))
lm(y ~ x, X)
and this works fine - whether you do an lm() before or after making ts
objects, it's okay.
But I have a situation where things aren't okay.

Help fit 5 nonlinear models. - Plant growth curves
Hi!! Can anyone help me, i have problems to converge the following
data with 5 nonlinears models that i evaluated.
Firtly, i send my data (totalsinatipicos) that i just try to fit with
the nonlinear models.
Next, i have the following script where i called the data as
totalsinatipicos. I made selfstarting each nonlinear model.

boxplot: reverse y-axis order
Hello,
Searching this forum has enabled me to get pretty far in what I'm trying to
do. However, there is one more manipulation I would like to make and I
haven't found a solution. Using the data and code below, I generate the
plot produced by the last command. If possible I would like to reverse the
order of the y-axis (bearing in mind horizontal=T) so that 0 is plotted at
the upper

x tick labels - sparse?
Hi,
I'm stuck on creating a plot with x tick labels for every Nth tick
mark - how is that done? I don't see a simple solution to this in
help(plot) or help(par) and what I've tried is not working, eg, the
following does not work, although it seems intuitive to me that it
should work:
x <- seq(-100,1000,25)
y <- x * x
% find all the x values that are multiples of 100

False alarm. For some reason that I have not yet been able to figure out, these tests run significantly more slowly when I run them during the daytime, which I did for that run. I checked a few of the worst regressions reported here and they all recovered in subsequent

Calculate Closest 5 Cases?
I've only begun investigating R as a substitute for SPSS.
I have a need to identify for each CASE the closest (or most similar) 5
other CASES (not including itself as it is automatically the closest). I
have a fairly large matrix (50000 cases by 50 vars). In SPSS, I can use Correlate > Distances to generate a matrix of similarity, but only on a small sample. The entire matrix can not
