Hello, I have a matrix (class matrix) composed of GridCell (row and column). The matrix value is the beta diversity index value between two grids. Now I would like to get the average value of each GridCell. Please kindly advise how to make the calculation. Thank you. Elaine The matrix looks like (cited from Michael Friendly) I would like to get the average value of each color. Obs

Alex, I was getting the following crashes when editing cells in a grid: ./init.rb:1072:in `main_loop'': undefined method `begin_edit'' for "_p_wxEvent":String (NoMethodError) from ./init.rb:1072 but only after the first App GC mark phase. So I changed all the GridCell*Editor.i files from GC_MANAGE to GC_MANAGE_AS_EVENT. Which stopped the crashing. My question

Hi all, (if me email goes out as html, than my email client don't do as told, and I apologies already.) We need to downscale climate data and therefore first need to expand the climate from 0.5deg to the higher resolution 10min, before we can add high resolution deviations. We basically need to have the original data at each gridcell replicated into 3x3 gridcells. A simple for loop can do

You probably ought to be using the raster package. See the CRAN Spatial Task View. -- Sent from my phone. Please excuse my brevity.

For all who are interested: A quick review of CeBIT 2005. :-) CeBIT was a very successfull event. Most of the time, the asterisk-booth was crowded with more people than we could talk to. We had with us a demo-installation including different IP-phones, digital and analog phones as well as a Siemens HiPATH PBX to which our Asterisk-server served as a VoIP-gateway, and many people were impressed

Hi, There is a severe problem with the db-1.85.4 library''s Linux port that can be found on sunsite.unc.edu under /pub/Linux/libs/db-1.85.4-src.tar.gz (sp?): This library contains a "snprintf" function which breaks down to a common sprintf, ignoring the size parameter. Obviously, this was thought to be a terribly bad work-around for C libraries which don''t contain an

Dear all, 'Apply' is a great thing for running functions on rows or columns of a matrix: X <- rnorm(20, mean = 0, sd = 1) dim(X) <- c(5,4) apply(X,2,sum) Is there a way to use apply for excluding rows or columns from a matrix to run functions on the remaining rows or columns? I know, I could do this with a 'for' loop, but 'apply' would be much easier and

How can I efficiently search for programs and packages that are available as part of the CentOs4.3 distribution? I am using CentOs4.3 and need to install packages that are apparently not part of this distribution. What RedHat version do I have to consider if I want to use rpm's for RedHat instead? Dirk

Dear R people I came across a strange thing: sd(rep(0.01, 15)) #0 sd(rep(0.001, 15)) #4.489023e-19 sd(rep(0.00001, 15)) #0 sd(rep(0.00000001,15)) #1.712427e-24 sd(rep(0.01, 13)) #1.805557e-18 sd(rep(0.001, 13)) #4.513894e-19 sd(rep(0.00001, 13)) #0 sd(rep(0.00000001,13)) #0 sd(rep(5.01, 15)) #0 sd(rep(5.001, 15)) #4.489023e-19 sd(rep(5.00001, 15))

Dear R-users I would like to draw a barplot with a special y-axis. Most of my data points are in the range from -50 to 50, apart from one value that is 550. I would now like to have a y-axis from -50 to 50, then a "break" and the "rest" of the y-axis, let's say from 500 to 600. In order to make clear what I'm trying to do, I attached a figure. Is it possible to do

How may one save a graphic as svg on Windows? The svg() command is recognized and functions well on Linux, etc., but not on Windows, it seems. I'm trying to use Hadley Wickam's ggplot2 and I would like to be able to save created charts as svg for later input into Illustrator. I am able to accomplish this workflow under Linux, but I don't know how to get R to recognize the svg() command

hello! i don't want to test my sample data for normality, but exponential- lognormal- or gammadistribution. as i've learnt the anderson-darling-test in R is only for normality and i am not supposed to use the kolmogorov-smirnov test of R for parameter estimates from sample data, is that true? can you help me, how to do this anyway! thank you very much! nadja

Hi: I am using a subset of the below dataset to predict PRED_SUIT for the whole dataset but I am having trouble with 'newdata'. The model was created with 153 records and want to predict for 208 records. wolf2 <- structure(list(gridcell = c(367L, 444L, 533L, 587L, 598L, 609L, 620L, 629L, 641L, 651L, 662L, 674L, 684L, 695L, 738L, 748L, 804L, 805L, 872L, 919L, 929L, 938L, 950L, 958L,

Hi I tried to customize help(), so it starts the compiled html help, and searches in all packages. I wrote the following function: > my.help function(topic){ help(topic, package=.packages(all=T), lib.loc=.lib.loc, chmhelp=T) } When I use it with >my.help(help) give the following error: Error in help(topic, package = .packages(all = T), lib.loc = .lib.loc, : No documentation

I need to install libMrm.so.3 on my computer that has Centos4.3. However, I am not experienced with Centos4.3 so far. I do not know where to find this library for Centos4.3 and how to install it. Is there something like apt? Using system-config-packages I cannot find any intelligent way to search for programs and package. Dirk

What's the most correct way of doing the equivalent to apply(x[,2:5],1,sum) if x is dataframe in which the only numeric fields are in columns 2:5 ?

Dear R users I am trying to sum selective elements of a vector but my solution is not cutting it. Example: > g <- 1:5; > from <- 1:3; > to <- 3:5; from to 1 3 2 4 3 5 so I expect 3 sums from g 1+2+3 that is 1 to 3 of g 2+3+4 that is 2 to 4 of g 3+4+5 that is 3 to 5 of g my solution will not work. sum.em <- function(g, c1, c2)
