Hi I just installed the gmodels package and the installation was successful but when I was trying to load the library I got an error (see below). Interesting, yesterday I wrote to the maintainer of RSQLite apckage because I got the same error. Does somebody knows what is going on ?? thanks, Mayte library(gmodels) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load

Dear all, One can use ks.test(x,y) for a one-sample kolmogorov-smirnov test: x being the data sample y being a string specifying a distribution I notice the help on ks.test does not tell you how to get such a list. Is this a hole in my R knowledge? Where can I get a list of the strings specifying the possible distributions? and more specifically What would be the string and following

Hi, there: After I upgraded my R to 2.4.1, it is my first time of trying to use MASS and found the following error message: > install.packages("MASS") --- Please select a CRAN mirror for use in this session --- trying URL 'http://cran.cnr.Berkeley.edu/bin/macosx/universal/contrib/2.4/VR_7.2-33.tgz' Content type 'application/x-gzip' length 995260 bytes opened URL

Dear R-help readers, I'm sure this problem has been answered but I can't find the solution. I have two vectors v1 <- c("a","b") v2 <- c(1,2,3) I want an easy way to produce every possible combination of v1, v2 elements Ie I want to produce c("a1","a2","a3", "b1","b2","b3") regards Desmond Desmond

i was searching for the source of bca.ci, a function of the package boot. I tried require(boot, keep.source=TRUE) but again the source was not viewable. How should i do?

Shuji, I suspect that bruto blows up because your data are linearly separable. To see this (if you didn't already know), try library(lattice) splom(~x, groups = y) and look at the first row. If you are trying to do classification, there are a few methods that would choke on this (logistic regression) and a few that won't (trees, svms etc). I would guess that bruto is in the latter

Hi all I want to conditionally operate on certain elements of a matrix, let me explain it with a simple vector example > z<- c(1, 2, 3) > zz <- c(0,0,0) > null <- (z > 2) & ( zz <- z) > zz [1] 1 2 3 why zz is not (0, 0, 3) ????? the null <- assignment is to keep the console silent in the other hand, it curious that null has reasonable values > null [1]

Dear, I have created my first package "G2Sd : Grain Size Statistiques and Description". I submitted it to the CRAN after I have checked the tar.gz file. All was ok, but since it is on the CRAN I can't install it : In getDependencies(pkgs, dependencies, available, lib) : package ?G2Sd? is not available (for R version 2.13.2) I've got the same message with R 2.14.1.

Hi i am using a script which involves the following loop. It attempts to reduce a data frame(zz) of 95000 * 41 down to a data frame (averagedreplicates) of 95000 * 21 by averaging the replicate values as you can see in the script below. This script however is very slow (2days). Any suggestions to speed it up. NB I have also tried using rowMeans rather than adding the 2 values and dividing by 2.

Hi I am trying to create a loop which averages replicates in my data. The original data has many rows. and consists of 40 column zz[,2:41] plus row headings in zz[,1] I am trying to average each set of values (i.e. zz[1,2:3] averaged and placed in average_value[1,2] and so on. below is my script but it seems to be stuck in an endless loop Any suggestions?? for (i in 1:length(average_value[,1])) {

Dear readers of the list, I have a problem a comparison of two data from a vector. The comparison yields FALSE but should be TRUE. I have checked for mode(), length() and attributes(). See the following code (R2.10.0): ----------------------------------------------- # data vector of 66 double data X =

Hello, and thank you for the answer. I'm quite new to Samba, and when you speak about Samba storing a crypt() password hash and about the virtualCryptSHA256 attribute I get the general meaning, but not the way to get to those informations. Would you have any pointer on where I could learn more about that ? I found discussions about some patches from Stefan Metzmacher in the mailing lists, is

Dear List, i would like to mimic the behaviour or the following indexing with a do.call construct to be able to supply the arguments to `[` as a list: test = matrix[1:4,2] result = test[2,] My try, however, did not work: result = do.call(`[`,list(test,2,NULL)) result = do.call(`[`,list(test,2,)) result = do.call(`[`,list(test,2,'')) How can I use the do.call in that way with

I'm having a problem with the mfg option of par. Am I making an error in my usage? Here is a simple example that I thought would plot to the 4 corners of a 2x2 plot but doesn't plot to the lower right and plots twice on the upper left. par(mfrow = c(2, 2)) pos <- as.matrix(expand.grid(1:2, 1:2)) for (ix in 4:1) { par(mfg = pos[ix, ]) plot(1:5) } Thank you in advance.

I have installed both 32-bit and 64-bit versions of R2.12.0 (2010-06-15 r52300) on my Ubuntu 10.04 64-bit system. I observe the following behavior when running the examples from base::connections. There appears to be a problem with seek() on a .gz file when using a 32-bit installation of R2.12.0, but the problem doesn't appear in the 64-bit installation. I realize that seek() has been

I've been using R actively for only the past few months under Mac OS X, but have found a few situations where I cannot get a package to load. This seems like the same situation reported recently on the thread "R-2.4.1 for MacOS X - languageR, acepack, Hmisc": > > library(Hmisc) > Error in dyn.load(x, as.logical(local), as.logical(now)) : > unable to load shared

Hello, I'm trying to use the package ttda, wich is involved in text analysis, for my own data about answers in a company survey.
