Hello, everybody, I hope somebody could help me with a dist() function. I have a data frame of size 2*4087 (col*row), where col corresponds to the treatment and rows are species, values are Hellinger distances, I should reconstruct a distance matrix with a dist() function. I know that "euclidean" method should be used. When I type: dist(dframe,"euclidean") it gives me a

Dear list, I have encountered a special case for searching a linear regression where I'm not satisfied with the results obtained using the traditional least squares method (sometimes called OLS) for estimating/optimizing the residues to the regression line (see code below). Basically, a group of my x-y data are a bit off the diagonal line (in my case the diagonal represents the ideal or

Dear guRus, I'd like to learn how to make a function recognize the name of an object/vector given as argument If I have : testFun <- function(x,y) plot(x,y, main=paste("plot of",names(x),"and",names(y)) ) # this just a simple example ... a1 <- 5:8 b1 <- 9:6 testFun(a1,b1) # Returns the plot, but not the names of the objects/vectors given as arguments, # but

Dear list, I'm wondering how to optimize functions/processes like the one shown below (which simplifies something we're trying to do with very large datasets). In many cases I've noticed that using apply, sapply etc can help speeding up processes, but in this case I don't see how I could do so. a <- runif(10000000,0.5,1.6) C <- 2 M <- 10000000 system.time( for (i in

Dear List, as I'm trying to install R and Rgraphwiz on a Fedora Linux, I have a problem with the environement variable "PKG_CONFIG_PATH". The library "libgvc" is not getting recognized / found, although a recent version libgvc is on the system and can be seen via /usr/lib64. I've tried to edit the paths described in /etc/ldpaths but without any success. Any hints how

hi all. how can i adress a array directly. for example i wanna give array 1 other labels than array 2. How can I overcome this problem? ...this doesn't work tab <- array(1:8, c(2, 2, 2)) dimnames(tab[,,1]) <- list(c("No","Yes"), c("No","Yes"),c("ARRAY1")) dimnames(tab[,,2]) <- list(c("big","small"),

Hi, I'm trying to realise a repport with R and Latex (TeXnicCenter and Miktex for Windows) using Sweave(). I'd like to save my plots in a given size. How can I do that ? The code is : \SweaveOpts{prefix.string = figs/plot, eps = FALSE, pdf = TRUE} <<partI, echo=FALSE ,fig=TRUE, include=FALSE>>= plotFunction() @ \includepdf[pages=-]{figs/plot-partI} When I use

Dear list, ?require says : "... |require| is designed for use inside other functions; it returns |FALSE| and gives a warning (rather than an error as |library()| does by default) if the package does not exist ..." However when I run the following code I don't get any TRUE / FALSE statements (but the warning only). Since I want to test from inside of a function if a given package

Dear all, Dear all, I am a relatively new user. I have an ascii file with 550 rows and 400 columns. The file contain values ranging from 1 to 2000 and some values with -9999. I want to generate a new file where the -9999 values are replaced with 0 values, the other values with the 1.0 value. What should I do, Thanks Taiseer

hello, i have a couple of .R files distributed about my file system. i commonly source() these from other files, but i have to include the full file path. this is not always convenient if you move files around. is there a way of setting the search path for source()? thanks a lot! cheers, andrew. -- Andrew B.

I have a code junk that produces a figure. In my special case, however, data does not always exist. In cases where data exists, the code chunk is of course trival (case #1), however, what do I do for case # 2 where the data does not exist? I can obviously prevent the code from being executed by checking the existence of the object x, but on the Sweave level I have a static figure chunk. Here an

Dear List, we're trying to install R on Solaris10 on a x86 (amd64). During the installation we pass successfully the ./configure but we get an error through the built-in function "_isnan" which we see existing in /lib When passing the command "make" we get : gcc -std=gnu99 -I../../src/extra/zlib -I../../src/extra/bzip2 -I../../src/extra/pcre -I. -I../../src/include

I have some questions about the RODBC package. library(RODBC) # required for those who want to repeat these lines 1st, I noticed that the following sequence does not work: channel <- odbcConnextExcel("test.xls") tables <- sqlTables(channel) name1 <- tables[1, "TABLE_NAME"] # this should be the name plan1 <- sqlFetch(channel, name1) # bang!

Dear list, I?m using R embedded in another program (coded in tcl/tk) under Windows Vista. In this context I don?t launch Rgui.exe but rather Rtem.exe. Now I have a problem finding libraries not specifically installed as administrator (and which are not in the path ?program files? but in Contacts\Documents of the current user). To be precise, the user launching my tcl/tk program can?t find

HI, R user, I generate the vectors with the same length. I want to put each vector into each column of data frame. Why it doesnt work`? rm<-data.frame() for(a in 1:6){ rm[,a]<-getmeasure(p1,a,speech) } thanks a lot Tammy _________________________________________________________________ Share your memories online with anyone you want.

Dear all I am trying to learn R I was trying to calculate standard deviation here are the commands and outputs in R > sd(Ht_cm[type=='SD'])[1] 3.283605> sd(Ht_cm[from_treeline=='above'])[1] 16.83289> sd(Ht_cm[type=='SD'][from_treeline=='above'])[1] NA> the problem is that, i could not understand why the third command could not give any result.

Dear list members, I have written a function, called say Analysis. I supply an Excel file name as an argument, it does analysis on this file and returns a pdf file with specific plots, and a text file with several statistical models' output (I extract certain values from the output and create my own custom dataframe with output). As of now I have to open the script file and load the function

Is there a way to convince R to create a character vector without using the quotes? This works ex1 <- c("first","second") but when I try this it doesn't ext <- as.character(c(first,second)) it complains. I have many variables to put into character vectors so dispensing with the quotes would be useful. Thanks Jim =============================== Dr. Jim Maas
