Full_Name: Axel Rasche Version: 2.1.0 OS: Win2000 Submission from: (NULL) (141.14.21.81) Hi, write.table does not accept the second statement with <col.names = NA, row.names = FALSE>. I do not see why this should not be possible. test = matrix(1:4, 2, 2, dimnames = list( c("a","b"), c("c","d") )) write.table(test, file = "test.txt",

Hi! I encountered some things trying to build own packages under Windows 2000 for which i found no answer in the documentation. First. 1. I do not found the rcmd.exe in the bin directory of R_HOME. I installed R using the setup.exe 2. I updated the R intatllation with one of the zip files. (rw1041sp.zip) now i had the rcmd.exe in the bin. 3. I do not found any hint in the docu that perl is

Is there a library that is able for example to 1. merge 2 dataframes by row eg.: rbind(dataframe1, dataframe2):data.frame 2. delete a column from a dataframe del(dataframe, colname) or del(dataframe, colindex= 1):data.frame? 3. Select lines from a dataframe by a specific function ? select(dataframe, func=small(x){x<1}, colindex=3): data.frame? 4. converting all double columns of a data.frame

Dear R community, Confused by some of my lab results I ask for the definition of the null hypothesis of a two-way analysis of variance in R (anova() and aov()). Starting with the following model y = a_i + b_j , i in A and j in B is the tested null hypothesis H_0: a_i = 0 for all i in A or H_0: a_m = a_n for any m and n in A? Consequently the same questions for interaction effects.

I have a vector with about 100.000 values representing a quite regular function (sinusoid like). I would like to find all local maxima of this function (should be about 4000). Is there a native routine for R? Thanks in advance Eryk. -- _|_ \|/ \|/ Eryk Witold Wolski tel :0049-(0)30-8413-1543 w w ?v? 'v? \'v'/ MPI Moleculare Genetik fax :0049-(0)30-8413-1139 |

Dear List, I'm trying to solve this simple optimization problem in R. The parameters are the exponents to the matrix mm. The constraints specify that each row of the parameter matrix should sum to 1 and their product to 0. I don't understand why the constraints are not satisfied at the solution. I must be misinterpreting how to specify the constrains somehow. library(alabama) ff <-

Hello, I urgently need a histogram of the vector geo1$ds1 but: > hist(geo1$ds1) Error in hist(geo1$ds1) : unused argument(s) ( ...)

The function heatmap() allows to specify row/column labels via the options labRow/labCol. From the code of heatmap(), I understand that when no labels are specified, the row/column labels (or indices) of the input matrix are taken as labels and re-ordered together with the rows and columns of the matrix before plotting, whereas labels supplied via labRow/labCol are plotted in the original order.

Hi! I am installing R in non standard directory. ./configure --prefix=/non/standard/directory The installation works fine. But after starting R i get .libPaths() /usr/lib/R/library but they cant be there of course! Have I to set some additional switches during config? Eryk Dipl. bio-chem.

hello I am returning to some libraries that I had previously customised by amongst other things adding additional functions. I had simply typed these new functions into the file in library/R/thelibrary. These however do not seem to be loaded now as they previously were under older versions of R. What's changed and what do i need to do? Thanks Stephen

Hi! I guess that it cant work. but maybee I am wrong. I would like to define a function rbind. > rbind function (..., deparse.level = 1) { which works only for objects of class Myclass Is it possible to use something like setMethod("rbind",signature(...="Myclass",deparse.level="numeric") This gives an error. Or should I use rbind.Myclass Eryk. Dipl. bio-chem.

This seems like a bug to me. Can someone verify this? First we define a function f that returns its second argument and lapply it to 1:2 using 9 as the second argument and all seems well. Note that "{" as a function does the same thing as f, as illustrated with f(1,9) and "{"(1,9); however, when we attempt to use "{" in the very same way we used f in lapply,

my major is bioinformatics, and i'm trying to cluster ( agglomerate the closest pari of observations ) in R. i have already got my own similarities metric, but do not know how to clust it based on similarities instead of dissimilarities. since the help document of hierclust mentions the parameter "sim", which seems good to me, but it doesn't appear in the code of hierclust()

Hi, a very basic question: What ist the easiest way in R to concatenate two lists of vectors? E.g, I have x<-list(c(1,2)) y<-list(c(3,4)) and I want to receive list(c(1,2),c(3,4)) thank you!

Hello All: This function obviously fails x <- function(z) paste("go", z, sep = ".") <- 10 x("now") But is there a way to define the name of a variable through passing a parameter in a function call? Thanks, ANDREW

Hi Keno, The part that scares me a bit is > and then adjust the other methods to not > bail out two quickly when encountering a weak symbol. I would very much appreciate if you could implement this; I don't have enough knowledge of the MCJIT nor llvm CodeGen internals... I will happily try it out and provide you with feedback, though! :-) Thank you *so* much for your fast reaction!
