I am trying to model the observed leaching of wood preservative chemicals from treated wood during an outdoor experiment where leaching is caused by rainfall events. For each rainfall event, the amount of rainfall was recorded as well as the amount of preservative chemical leached. A number of climatic variables were measured, but the most important is the amount of rainfall. I have tried a

Howdy, I''m using Apache 2.2 + Mongrel with great success, using the sample configs from the Mongrel site. We have some MP3s on the site and recently someone has been stealing them and basically leaching them from the site, linking to them from an off-site location. I''ve been trying to modify my Apache conf to check the referrer and adjust accordingly as below but no

My R script needs to pause or wait for a key or mouse on each graph. I used the following statement after each plot par(ask=TRUE) This works on Windows but not on MacOS. Is there any way to pause on graph in MacOS? Thanks, Vu [[alternative HTML version deleted]]

Hello R community, I am using R for creating a model using optimization. I would like to ask if there is R-function/package for solving the problem below: Minimize sum(abs(exp^(Ai1 x1 + Ai2 x2 + ... + Aim xm - bi) - 1)), for each i = 1, ..., n. subject to Ai1 x1 + Ai2 x2 + ... + Ajm xm - bi <= c, where c is a scalar. (x is a vector of variables, A is nxm matrix, b is a vector)

I have a recurring graphics issue that I've not been able to resolve with R. If I make a series of regression estimates and then plot the estimated function for the regression lines over a scatter plot of the data, e.g., using a sequence of plot( ) and lines ( ) similar to those below

It may sound very simple: 1. When a user request some file, the program should authorize him 2. Then we send the file location to the browser/download manager so it can begin to download. (something equilvalent to PHP header ("Location: XXX") 3. Do something else before we stop the script. The hardest part is the 3rd one, when we send back the header the script will stopp too. I was

Hello all, Years ago, I used to work with tripwire for system monitoring. Last time I checked with "yum search tripwire", there is no hit. IIRC, it used to be packed by default on older Redhat distros. Any suggestion for an alternative of tripwire for my CentOS 5.6?

hi users a novice here hoping to grasp fundamentals soon I have a samba+sssd as a client to an AD - I have all the keytabs for a host(I think) but I noticed weird(to me at least) smbclient behavior. when I do: $ smbclient -L swir -U me at AAA.PRIVATE.DOM -k all works, clients sees local samba's shares, when I do: $ smbclient -L swir.private.aaa.private.dom -U pe243 at AAA.PRIVATE.DOM -k

I have two vectors, a and b. b is a text file. I want to find in b those elements of a which occur at the beginning of the line in b. I have the following code, but it only returns a value for the first value in a, but I want both. Any ideas please. a = c(2,3) b = NULL b[1] = "aaa 2 aaa" b[2] = "2 aaa" b[3] = "3 aaa" b[4] = "aaa 3 aaa"

Hi all: since about a month we encountered a problem with R -e command: spaces in the "command" of R -e "command" are no more tolerated. This same issue affects 2.11 patched (05-05-2010), 2.10.1, and current devel (at least the one of two weeks ago). (I skip the mid of the printouts, replaced with ...) * R -e "message('aaa aaa')" ARGUMENT

I am seeing an issue with getting certain sip devices to be recognized as defined SIP clients host= in the sip.conf and the only deference that I can find btw sources that work and don't work is that devices that send packets with an Initial Via header of themselves appears to work and pick the context correctly but those that don't have the Via just get dropped in the context of the

After a lot of processing I get a matrix into M. I expected each row and column to be a vector. But it is a list. R-Inferno says... "Arrays (including matrices) can be subscripted with a matrix of positive numbers. The subscripting matrix has as many columns as there are dimensions in the array—so two columns for a matrix. The result is a vector (not an array) containing the selected

I am trying to do the simplest thing in the world. The following works: aaa <- ifelse(aaa==5, 6, 7) But if I want to change the if...else syntax instead, it gives errors and assigns 7 to aaa. Here is the problem code: aaa <- 5 if ( aaa==5 ) { aaa <- 6 } else { aaa <- 7 } Here is the output: > aaa <- 5 > if ( aaa==5

Hi, I would really like to have a way to split long string literals across multiple lines in R. Currently, if a string literal spans multiple lines, there is no way to inhibit the introduction of newline characters: > "aaa + bbb" [1] "aaa\nbbb" If a line ends with a backslash, it is just ignored: > "aaa\ + bbb" [1] "aaa\nbbb" We could use
