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.

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

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

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

Greetings I'm having difficulty witht the strptime function. I can't seem to figure a way to strip month (name) and year and create separate columns from a column with MM/DD/YYYY formatted dates. Can anyone help? Cheers Kurt *************************************************************** Kurt Lewis Helf, Ph.D. Ecologist EEO Counselor National Park Service Cumberland Piedmont Network

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

Greetings How do I do this in R? Checking the Cran site produces a bewildering array of packages that I can't seem to find to load. Surely the main program has this function?

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

dear R users, I need some help for multivariate analysis. I have 2 anaesthetic treatment groups (20 patients/group) where I register heart frequency and pressure for 60 min (repeated measures every 5 minutes). I would like to perform a test to check if treatments are different in controlling freq and pressures during the anaesthesia, but i would like to have also an overall measure and not

Hello, I have a small problem which has grown (and continues to grow) over the years. I have upgraded my linux system so many times, I''m worried that I have old, insecure libs and executables somewhere on my system which may or may not be used to gain access to my system. How do I determine which libs I should have where, and which libs are safe to delete? There are some programs

Greetings- We use smbclient -M to send a Message of the Day to clients every once in a while. The clients are NT4 (SP3), and the server is Samba 1.9.19-prealpha. However, the same problem appears with version 2.0.0. The issue is: once the file to be sent exceeds approximately 675 bytes (smbclient reports sending 975 bytes, presumably including some overhead), the message turns up blank on the

I've attached a perl script that I wrote to build smbpasswd from /etc/passwd. Please note that this writes a samba-2.0 format smbpasswd file. This script will: # - create accounts that exist in /etc/passwd and not in smbpasswd # - remove accounts that exist in smbpasswd and not in /etc/passwd # - preserve existing password, flags and LCT fields in smbpasswd # - sets new account passwords to

Is there a way to estimate a nominal response model? To be more specific let's say I want to calibrate: \pi_{v}(\theta_j)=\frac{e^{\xi_{v}+\lambda_{v}\theta_j}}{\sum_{h=1}^m e^{\xi_{h}+\lambda_{h}\theta_j}} Where $\theta_j$ is a the dependent variable and I need to estimate $\xi_{h}$ and $\lambda_{h}$ for $h \in {1...,m}$.

Dear R helpers, I have a data set with 4 types (W, C, E & S). Now I have values for all types plus all possible combinations (the order is unimportant): W, C, WC, E, WE, CE, WCE, S, WS, CS, WCS, ES, WES, CES & WCES. Ideally I would like to represent everything in one graph and as concise as possible. Drawing 4 circles and depicting it as overlap just gives me 13 out of the 15

Dear R-helpers, I would like to export hierarchical clusters e.g. fit <- hclust(d, method="ward") in the newick format write(hc2Newick(fit),file='hclust.newick') Searching for a possibility I found this solution in the package ctc (http://www.bioconductor.org/packages/bioc/html/ctc.html). However, neither from this site nor via CRAN it is possible to install the package.

Does anyone know how to read a SYSTAT .syd file on Linux? (Splus 6 does it, but it is easier to find a Windows box with Systat than to download their demo. I'm wondering if there is a better way than either of these options.)

Dear R Help Members, I am aware how to plot the LD1 vs LD2 from a lda in R, using the code: plot(baseline.systat.hat$x, col=baseline.systat.hat$class,pch=as.numeric(baseline.systat.hat$class)) However, I need to use the quadratic discriminant function, qda due to data properties. Is there a way to obtain the same sort of plot for from a qda object (and the output of predict qda). I have not

Thanks in advance for taking the time to read this email. I'm using rsync to make a copy of my Netbackup Catalogs to an offsite server for DRP. I have narrowed the problem down to a few sub-directories that contains 16 directories each and in each directory there are about 37 files. None of the files are larger than 300MB. In fact, most of them are around 1K-5MB. The problem is, rsync
