Hi, I have a 1-column dataframe with rownames and I want to sort it based on the single column. The typical procedure that is recommended in diverse posts is to use order in the index. But that "destroys" my dataframe structure. Probabaly it is a very simple solution. Here is a short reproducable example: x <- c(1,3,51,2,34,44,12,33,2,8) df <- data.frame(x) rownames(df) <-

Hi, I have a dataframe and want to remove columns from it that are populated with a similar value (for the total column) (the variation of that column is 0). Is there an easier way than to calculate the statistics and then remove them by hand? A <- runif(100) B <- rep(1,100) C <- rep(2.42,100) D <- runif(100) df <- data.frame(A,B,C,D) # if want to conditionally remove column B and

Hi, it is easiest to explain what I want to do by an example: lets assume there are two factors/variables: A <- c(1,2,3) B <- c(1,3,3) Now I would like to generate a list of strings that should look like ("A1_B1","A1_B2","A2_B1","A2_B2"). So actually the string contains all possible combinations of A and B (separated by _). This should be also

Good day! I'm having trouble changing certificate/keys for my dovecot(version 1.2.9). When I set up the server (unbuntu lts 10.4.4) I did it with a self-signed certificate. I can't remember exactly what I did, just that I followed the wiki and it worked fine =) Now I have to change the certificate because a friend bought an official one (from thawte) and I'm a bit stumped. As dovecot

Hello, I want to use a for loop for repeadely calculating a maxent model (package dismo, function maxent()) which creates an object of the class maxent (S4). I want to collect all the resulting object in a list. I tried to simplify my for loop to explain what I want. There are two problems/questions: 1) How can I create the new variables in the loop (using paste) and assign the objects 2) How

Dear all is it possible to rsync in a master-slave scenario saving to slave gzip content? i'm not talking about compression during transfer, i'm talking about -saving- the destination in a compressed format. Example: FROM: -folder_A --file_A --file_B TO: -folder_A --file_A.gz --file_B.gz I know that this won't be a "real" rsync between two folder, but it will be an

Estimados erreros, Estoy intentando entender como calcula el paquete dismo ( https://cran.r-project.org/web/packages/dismo/index.html) un coeficiente de variación. Os pongo un ejemplo: tmin <- c(10,12,14,16,18,20,22,21,19,17,15,12) # temperatura mínima media mensual de un año tmax <- tmin + 5 # temperatura máxima media mensual de un año prec <- c(0,2,10,30,80,160,80,20,40,60,20,0)

Dear all, when using .jinit() I get the message .jinit() : Cannot create Java virtual machine (-1). The details: I am using the Dismo package.Dismo has a function 'maxent' that communi-cates with this program(MaxEnt).MaxEnt is available as a stand-alone Java program. It is normal when I execute the command : "jar <- paste(system.file(package="dismo"),

Hello All - I'm looking for a switch(es) to ensure rsync indexes the pull of files from remotedir, LIFO (last in first out) and then by .ext type where file basenames are similar. example) file_a.xml ctime of 09:01:07 file_a.jar ctime of 09:01:02 get transfered before file_b.xml ctime of 09:01:45 file_b.jar ctime of 09:01:45 and the .xml of basename $file would always be transferred

Dear R-helpers and Dr. Hijmans, I can not invoke maxent() in GNU Linux. Could you give me any directions on that? There is maxent.jar in version 3.3.3e in the right folder. ######################################## R: > jar <- paste(system.file(package="dismo"), "/java/maxent.jar", sep='') > jar [1] "/ebio/abt6/jmao/rpacks/dismo/java/maxent.jar"

Dear all, I get the error when I use maxent.jar: Error .jcall(mxe, "S", "fit", c("autorun", "-e", afn, "-o", dirout, : java.lang.NoSuchMethodError: density.Params.readFromArgs([Ljava/lang/String;)Ljava/lang/String; sessionInfo() result: R version 2.14.0 (2011-10-31)Platform: i386-pc-mingw32/i386 (32-bit)locale:[1]

random selection of cells in raster based on distance from xy locations Hi, I am trying to sample a raster for random cells that occur within a specific distance of point locations. I have successfully found multiple ways of doing this but have memory issues with very large datasets. To overcome this problem I am working with lists. I am now stuck on how to randomlly sample the correct elements

Regarding the following extract of ?options: ?editor?: a non-empty string, or a function that is called with a file path as argument. edit.default currently calls the function with three arguments: name, file, and title. For example, running the following vimCmd <- 'vim -c "set ft=r"' vimEdit <- function(file_) system(paste(vimCmd, file_)) options(editor =

Hi Tanmay, >Does compiling speex API with DISABLE_FLOAT_API and DISABLE_VBR solve the >problem? I remember that this fixed the problem. But at that time I also needed VBR so this was not an option. As far as I know, it is related to some calculations that involve float denormals that cause the high CPU usage. Today I'm still using the following code before speex_encoder_init and

Hi, I am trying to do plot a scatterplot matrix using pairs() from the package graphics. There are now a few things I'd like to improve for a better understanding. 1) My scatterplot uses two log-scaled axis...as I don't know how to set them in pairs() I calculated the log before but now the labels are not as I want them. I'd like them as 10^1,10^2 etc. What is the best way to handle

Hi, I want to create a pdf of my Man-pages from my package. Therefore I run in the terminal Rd2pdf on the package and a pdf of all the pages is created. After the titlepage there is the general package page, which includes "Description" and "Details" etc. Unfortunately after the Subtitle "Details" there is a pagebreak (and 3/4 white page) which I did not set

Hi, I am wondering if anybody has experience with scatterplot matrices where some (but NOT all) axis are transformed and the labels are nicely plotted. So far I looked into 1) pairs() 2) scatterplotMatrix() from package 'car' 3) splom() from packagae 'lattice' 4) plotmatrix() from 'ggplot2' I can see no easy way to get what I want which is: *) a scatterplot matrix of
