Samba 3.0.3 on FC2: windows machine cannot join domain

extracting RGB values from a colorspace class object
Greetings,
After pouring over the documentation for the 'colorspace' package, I have not
been able to figure out how the plot() method converts colorspace coordinates
to RGB values for display on the screen. I am convert between colorspaces
with the various as() methods... but cannot seem to find a way to extract RGB
(i.e. for displaying on a computer screen) triplets from color space

Re: Samba 3.0.3 on FC2: windows machine cannot join domain
After, oh, six months of attempts here and there to read everyone's
experiences with Samba/LDAP and inability for a windows 2000/XP machine
to join the domain, I finally discovered what was not working properly.
In my smb.conf I put:

As instructed by many How-to's and Idealx. However, I thought to myself,

Adonis and nmds help and questions for a novice.
Hi,
forgive me if someone has already posted about this but I have had a look and cannot find the answer, also I am very new to R and been getting the grips with this.
I have been trying to use Adonis to find out if there are significant difference between groups on data that I have analyses with NMDS, and have been struggling with getting this to work and understanding what is going on. I am

akima interpolation and triangulation question
Dear all;
First of all, this is probably a more conceptual question than a
R-related one, but still want to give it a try. When working with the
interpolation function "interp" from the package akima and the
triangulation function "tri.mesh" from package tripack I've got NA's
for the interpolation and "error" for the triangulation. The data is
arranged in a

Re peated ANOVA or nested ANOVA, or parallel one way ANOVA six times?
Hi, every body!
I am a new comer for R, so my question would unavoidablely sounds stupid.
Sorry!
In my experiment, there are two type of soil ( soil F and soil D), each half
of them were subjected to steam sterilize (result in FS and DS soil). A
equal volume of soil from two of the four soil types (F, D, FS, DS) were
mixed as follows: F+F, F+D, F+FS, F+DS, D+F, D+FS, D+DS, FS+DS (eight

prevent aov re-ordering of model terms
Is there a way to prevent the re-ordering of factors by aov? I do have a
three-way interaction that I do want to fit before a two-way interaction
(different factors, so they are not nested), but R moves the two-way
interaction to the front. I know it generally makes sense to fit the
two-way interactions first, but in this case I think I know what I'm doing.

Ordering scales in xYplot.Hmisc
Dear R community,
I am using xYplot() from the Hmisc package. The package works great to
plot means + CI. But I am having issues handling the scales.
I am plotting "Soil Clay content" vs "Soil depth" by "land use".
Usually in this type of graphs it is better to place the variable "soil
depth" in the y-axis and it should be ordered downward by depth (0-5

tree mortality risk model using glm()
Dear all,
I've used glm(family=binomial(link="logit")) several times, but now I think
that a log link is more appropriate.
I want to fit a model for probability of tree fall (TF)), with tree
diameter (dbh) and soil moisure (soil) as predictors. A large number of
trees have been checked every second year whether they stand up (0) or have
fallen (1).
I assume that the tree fall

Fwd: netCDF to GeoTIFF by layer in r
Hi
I have a netCDF file of volumetric soil water content at four

one GeoTIFF layer, i.e. unclear which soil depth.

Repeated Measures, groupedData and lme
Hello
I am trying to fit a REML to some soil mineral data which has been
collected over the time period 1999 - 2004. I want to know if the 19
different treatments imposed, differ in terms of their soil mineral
content. A tree model of the data has shown differences between the
treatments can be attributed to the Magnesium, Potassium and organic

Random structure of nested design in lme
All,
I'm trying to analyze the results of a reciprocal transplant experiment using lme(). While I get the error-term right in aov(), in lme() it appears impossible to get as expected. I would be greatful for any help.
My experiment aimed to identify whether two fixed factors (habitat type and soil type) affect the development of plants. I took soil from six random sites each of two types

Time-series analysis with treatment effects - statistical approach

I'm struggling to select an appropriate statistical method for my data set.
I have collected soil moisture measurements every hour for 2 years. There
are 75 sensors taking these automated measurements, spread evenly across 4
treatments and a control. I'm not interested in being able to predict soil

I did pretty much the same thing you did and had no problem. In the data/

else. Did you try installing the package and test it before you run check?

questions regarding spline functions

Here is an example of a set of depths, with associated attributes for a given

soil horizon boundaries:
