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 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 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

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.

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'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 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 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

This is my first time to ask for help in the R mailing list, so sorry for my misbehavior. The question is actually an example of the apply function embedded in R. Code is here: > x <- cbind(x1 = 3, x2 = c(4:1, 2:5)) > dimnames(x)[[1]] <- letters[1:8] > x x1 x2 a 3 4 b 3 3 c 3 2 d 3 1 e 3 2 f 3 3 g 3 4 h 3 5 > cave <- function(x, c1, c2) c(mean(x[c1]),

Hi, I am an applications engineer for Texas Instruments in the UK. I am trying to port the CELT codec to the C5505, this has HW accelerated FFT engine (http://focus.ti.com/docs/prod/folders/print/tms320vc5505.html). I am having problems with the stack allocation. Do you have any reference code that compiles for the C55x under CCS (code composer studio)? *******************************

Hi, I wonder whether the mechanism of parsing parameters to functions has changed between 0.63.1 and 0.63.3? The following code yeils different results in R 0.63.1 (Version 0.63.1 (Dec 5, 1998)) and R 0.63.3. cave<-function(x,a,b) { return(c(mean(x[a],na.rm=T),mean(x[b],na.rm=T))) } datx <- data.frame(rbind(c(1,2,3,4),c(4,5,6,7)))

Greetings, Yet another strange pattern of traffic is being halted at the shorewall firewall, but I have no idea what this is. IANA shows the ports unassigned, and a net search yields only some of the same questions - what is this port? There are two machines as SOURCE, on the same class C network, adjacent, even, sending one connect attempt to TCP port 32230 every five minutes. I''m

All, I am having trouble with the getent passwd and getent group command. I am using 2.2.4-4 version of Samba on a redhat system with 2.4.18-SMP kernel. This issue seems to be intermittent. Sometimes is works and others it doesnt. More often than not, it failes. I can do a wbinfo -g and -u and get the info so I am connected to the doamin, but not getent. This will affect my users from loging
