UID mapping
Hi,
I'm trying to convert an old system on Solaris 10 that uses the
smbpasswd file authentication method to a system that authenticates
against Active Directory. I've managed to get winbind working but of
course this just allocates UIDs as it sees fit whereas the smbpasswd
file method used the UID from the /etc/passwd file. The user codes on
the Solaris server match the user

Help with permutation function from Turner et al. 2010 (Ecology)
Hello,
I'm using R code that includes a residual permutation that was written as a supplement to the paper:
Turner et al. 2010. A general hypothesis-testing framework for stable isotopes ratios in ecological studies. Ecology 91:2227-2233.
The supplemental code is available at: http://www.esapubs.org/archive/ecol/E091/157/suppl-1.htm
When I execute the function, no warnings are given

Singling out observations
Greetings
I am attempting to plot observations of a cave aquatic invertebrate
dating from 1901-2004. I can come up with a nice lattice plot of the eight
sites from which I have data easily enough. However, I'd like to be able
to highlight the 0 observations on the plots, i.e., attempts to find it at
the site were unsuccessful. I'd like to be able to highlight these
observations

Does anyone have any suggestions for reducing pdf file size,
particularly pdfs containing photos, without sacrificing quality? Thanks
for any tips in advance.

readRegistry function (PR#12937)
Full_Name: Zivan Karaman
Version: 2.7.2
OS: Windows XP
Submission from: (NULL) (195.6.68.214)
I'm puzzled by the readRegistry function.
Shouldn't the "hive" argument be something like
c("HLM", "HCR", "HCU", "HU", "HCC", "HPD") rather than
c("HLM", "HCR", "HCU", "HU",

hclust and heatmap - slightly different dendrograms?
Good afternoon,
I ran heatmap and hclust on the same matrix x (strictly, I ran
heatmap(x), and hclust(dist(t(x))), and realized that the two
dendrograms were slightly different, in that the left-right
arrangement of one pair of subclusters (columns) was reversed in the
two functions (but all individual columns were grouped correctly).
Looking through the code for heatmap as a most definite

Confusing error statement
Greetings
Using the following command I've been trying to subset a dataframe of
counts of an organism to compute the sizes of groups for use as a
predictor:
Hs.patches <- as.data.frame(with(Hs.long,
table(Cave,Year,Month,Region,Plot,)))
I am getting the following error message that I do not understand:
ERROR: argument is missing, with no default
Can anyone shed light on this

Unbalanced data in split-plot analysis with aov()
Dear all,
I'm analysing a split-plot experiment, where there are sometimes one or
two values missing. I realized that if the data is slightly unbalanced,
the effect of the subplot-treatment will also appear and be tested
against the mainplot-error term.
I replicated this with the Oats dataset from Yates (1935), contained in
the nlme package, where Variety is on mainplot, and nitro on

substituting level for NA in factor column
Greetings
I have a bunch of NAs in a column of categorical variables designating
the size classes (e.g., smallest to largest: 1,2,3,4) of cave crickets.
I'd like to substitute "U" (for unknown) for the NAs. Can anyone give me
an idea how to do this? Thanks in advance.

Suppress horizontal mean line in beanplot()
Hi,
I would like to use the beanplot() function from the beanplot package.
Unfortunately, I can't find out how to suppress the dashed horizontal
line, that shows the overall mean.
In the help I've found the argument "overallline", but it only allows
for "mean" or "median" .
I have tried overallline = F, overallline="n", and

Months in alphabetical order rather than chronological order in graph
Greetings
Though I have months in chronological order in my data table, the data
were sampled every other month (i.e., February, April, June, August,
October, December), every time I try to plot them (on the x-axis) they are
plotted in alphabetical order. What am I missing?

remove numbers from string of characters
Greetings
I want to remove numbers from a string of characters that identify
sites so that I can merge two data frames. For example, a site in one
frame is called "001a Frozen Niagara Entrance" whereas the same site in
the other data frame is called "Frozen Niagara Entrance". It seems to me
the easiest thing to do would be to remove the numbers from the first data

Inserting Missing Data

I'm attempting to insert missing data on the smallest size class of

R-help Digest, Vol 91, Issue 21
All
Is there a script in R equivalent to the "if then" transforms one can
perform in Systat? For example, I want to create a "Treatment" column
coded either 1 or 2 for twelve field sites in a large data set. Ideally,
I'd be able to tell R to code sites a-f as 1 and sites g-l as 2.
