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

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

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? Cheers Kurt *************************************************************** Kurt Lewis Helf, Ph.D. Ecologist EEO

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
Greetings I'm attempting to insert missing data on the smallest size class of cave cricket instars into a data frame. The data involve censusing photoplots (plots) of roosting cave crickets in which we discern in four instars or size classes. I need to insert data on size class one into a data frame that already has data on size classes two through four. The data can be merged by their

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.
