Post-Hoc Test for Kruskal-Wallis Rank Sum Test
Hi list,
I would like to know if there is a way in R to execute a post-hoc test
(factor levels comparison, like Tukey for ANOVA) of a non-parametric
analysis of variance (kruskal.test() function object). I was looking for
something like the Dunn Test. I’ve searched the internet but nothing seemed
to define a way to it.
Do You have any suggestion? Other equivalent test maybe!
Thanks in

R Mixed Anova
Hi list, I was searching how to properly write a command line for a mixed
ANOVA. Well honestly, there are so many material on the older post of the
list that just confused me.
I have five factors.
Season (fixed)
Beach (fixed)
Line (fixed)
Block (random)
Strata (random) nested in Block
And for each of the tree strata per block I got 3 replicates.
I saw lots of things about

Customized LDA (MASS) object plot
Hi R experts.
I performed an Linear Discriminant Analysis (lda) and now I want to plot the
first two axes (LDA1 and LDA2). Well MASS package have the plot.lda and
pairs.lda to do that. But, they don’t let me personalize them, once they
don’t accept the type=’n’ plot. So I start looking at the lda object
properties, trying to found out my groups (n=4) axis coordinates, curiously
I couldn’t. There

Symbols on a capscale object plot
Hi, I'm a beginner with R, but I'm getting excellent results with it.
Well I've got an capscale object (vegan package) and I want to made a biplot
with symbols representing six groups of areas.
With the plot.cca function and some par attributes (like 'labels') I was
able to substitute the samples names for keyboard symbols ('x','o','#',ect),
but it's

Arc/Info Ungenerate - shp - Maps
Hi list.
I would like to know if someone had already successfully loaded and Arc/Info
Ungenerated (.dat – extracted from
http://rimmer.ngdc.noaa.gov/mgg/coast/getcoast.html) file on R. I’m able to
do so with shape files using maptools functions, but these ungenerated data
are making me crazy.
I don’t have any of ArcGIS tools (one of them probably can do that), and I
can’t find any free tool that

Two Factors and a Numeric Variable in a Plot
Hi list.
I'm trying to plot a graph "by" factors. Exactly, the x axis are my depths
(as.factor), my left y axis are my transects (also as.factor) and I want to
plot the mean and standard deviation (three samples per factor combination)
of my SW (numeric) variable. The second y axis (at the right) will,
probably, need to be displayed several times (for both left y axis

PostScript File Dimensions
Hi List, here I go again.
Well I need to save plotted objects as .eps using the postscript() function,
well I can do that but all resulting object are perfect squared dimensions
(x = y). I need a rectangular output something like x = 2y dimension. Is it
possible? The I’m new to R and postscript image format!

Text Contrast in a Plot
Hi List,
I would appreciate any suggestion on how can I make a text I’ve inserted in
a plot show some contrast? With this I mean that I have a white text on a
plot and I would like to make a tiny border around it in black, so even
being small sized and the entire graphic being small in the text page I’ll
insert it. It will be visible.
Well I tried inserting a box() function inside the text()

1-Pearson's R Distance
Hi again List,
Well this time I’m writing for a friend (really J). He needs to create a
distance matrix based on an abundance matrix using the 1-Pearson’s R index.
Well I told him to look at the proxy package, but there is only Pearson
Index. He needs it to perform a clustering. Well, as soon as he told me
there proxy only had the Pearson index I thought: “He could just do

Mirror Image on Biplot Graphic
He everybody,
Well I have a biplot CCA-like origined from plot.cca (vegan package). I need to rotate on y axis the lines and symbols of constrained and sites representation. If I do that on an image editor, I rotate everything, including titles, axes labels and positions. I just need to rotate the inner par and keep the variables names (constrained) and symbols in the new positions but with the

Bubble Plot Over a Map
Hi everybody,
Well here is another doubt! I’m elaborating some maps, and I pretend to plot
over it the abundance of species. I could do that using points(), but I’d
like to use bubble() from sp package.
When trying to use bubble() I face the fallowing issue: When I call the
bubble function it overwrite everything I previously plotted. It doesn’t
happen with points (obviously), only with

Barplot Labels Problem
Hi everybody,
well I'm trying to use barplot for the first time. I get a suitable graphic but I'm having a weird problem.
My graphic is generated from a matrix with several species (rowNames) and two abundance columns.
So each species will have two bars, and the species name should appear at left. Until now everything is Ok, but when a I plot it the species names (my labels) are cut by

Avoiding Biplot Labels Overllaping
Hi everybody,
I'm trying, without success, to avoid some variables labels to overlap on a capscale (vegan package) object graph.
I was able to move the labels with the coding below, but it moves the entire vector...

for(i in c(2:8))CAPobj$CCA[[i]][,1]<-CAPpotiFTI$CCA[[i]][,1]
CAPpotiFTI$CCA[[i]][,1][2]<-0.85

How do I plot multiple XY plots on the same graph
Hello,
I have multiple data sets I would like to plot on the same XY scatterplot.
The data sets have in common the same Y values.
Could somebody tell me how to do this?
I tried par(T=new) (I think this was it) but it literally overlays plots on each other.
Thanks in advance.

Change the Order of a Cluster Topology
Hi list, recently, for didactic reasons, I had the need to change a cluster
topology (just the order of my groups, defined in an height of choice), not
the results, obviously. Well I’m looking at hclust or agnes (cluster
package) objects for something that defines the line breakings of the
graphics, so I could try something to change this plot ordering. But, I’m
unable to figure that out.

Multiple XY Lines Plot
Hi list, I’m trying to plot lines in the same graphic. There are lots of
similar topic on the list history. I’ve read about xyplot (lattice) and
other ways to do that but I only got complex error messages, and wasn’t able
even to start a decent R scrip. Well I have some paired information (each H
W ), were H is the y axis and W is the x axis, how could I plot all the four
lines at the same image?

Plotting a kriging on a map
Hi list,
Well, this time I’ve a doubt with mapping generation.
I was already able to read and plot shapefiles, plot point on this map. All
this without any problems, but now I want to do something that I think, only
Golden Software Surfer is capable of.
I would like to plot a kriging result on the existing map (map script
below). Well I looked for on the net, but I was not able to be sure of
