Hi all, please excuse- I'm a complete newbie to R, so it's possible my question was asked a thousand times before, but I don't get it :-( I imported a CSV file via: x=read.csv("test.csv",header=TRUE,sep="\t") In a column there are values with the dot-character (".") I want to replace with a commata: > x[9] ?????????????????? V16 1???????? GPS

Greetings, fellow R'ers. How can I get this frame in R: ID meas ID.1 meas.1 1 1.1 3 1.2 2 2.1 4 2.2 to look like this (stacking): ID meas 1 1.1 2 2.1 3 1.2 4 2.2 It's not really the reshape function (or is it?) because we can consider the additional columns, viz., ID.1 and meas.1, as independent of ID and meas so it is basically a stacking

For some time I have been using rsync to backup data between different machines and my NAS drive. But within the last 2 days I have found out that rsync is not removing old files from destination - directories renamed or removed from source. In this example I want to sync files on my Debian Linux server to a NAS drive. NAS drive is mounted using smbmount. Using "-avhzn" dry-run it

Hi, I'm trying the brlr function in a penalized logistic regression function. However, I am not sure why I am encountering errors. I hope to seek your advice here. (output below) Thank you! Your help is truly appreciated. Min-Han #No error here, the glm seems to work fine >

I find one row in my large dataset. But when I use the "rownames" for the data on the 100,000 row, the result show nothing. I try it by the following example, it still likes that. > tst[rownames(tst)==100000,] [1] x y <0 rows> (or 0-length row.names) ############## > tst=data.frame(x=1:200000,y=200000:1) > tst[rownames(tst)==1,] x y 1 1 200000 >

Hi, All: Is there a simple way to detect complex conjugates in the roots returned by 'polyroot'? The obvious comparison of each root with the complex conjugate of the next sometimes produces roundoff error, and I don't know how to bound its magnitude: (tst <- polyroot(c(1, -.6, .4))) tst[-1]-Conj(tst[-2]) [1] 3.108624e-15+2.22045e-16i

I have a problem where I need to loop over the total combinations of vectors (combined once chosen via combinatorics). Here is a simplification of the problem: STEP 1: Define three vectors a, b, c. STEP 2: Combine all possible pairwise vectors (i.e., 3 choose 2 = 3 possible pairs of vectors: ab,ac, bc) NOTE: the actual problem has 8 choose 4, 8 choose 5 and 8 choose 6 combinations. STEP

Hi, just a small follow up of recent discussions about Elphel's JP4 format. I'm working with Andrey and fellows from Elphel to improve support for JP4 format in the context of Elphel's Apertus project (http://www.apert.us). As posted by Basil, on http://wiki.elphel.com/index.php?title=JP4 there is plenty of information about the format and how to post process it to get back your real

Dear useRs, How come the first attempt to sort a POSIXt vector fails (Error: non-atomic type in greater), while the second succeeds? (Code inserted below.) The documentation says that POSIXt is used to allow operations such as subtraction, so I'd expect sorting to work. Is this perhaps an OS issue? (I run R 2.0.1 on Win xp.) Thank you, b. #------------code test <- c("2005-02-08

Hello. I cannot install syslinux on my hard disk image. Steps to reproduce the problem: (1) Create a zeroed disk image with 800 tracks, 32 sides, and 63 sectors or 825753600 bytes (2) Fdisk and format it with "format.com /S C:" from windows 98SE boot disk. (3) Copy syslinux (tested version 3.11, 3.20, and latest released) to root. (4) Run "lock C:" and press

Hi, I am working with lists whose terms are lists whose terms are lists.

Hi All... I haven?t found mention of this error anywhere. I'm trying to draw spline curves using grid graphics. Most of the time, I have no problems, but I have some data sets that give the error in the subject line. I'm not sure which end points are identical, but the end points passed to the function are definitely not identical. Any assistance appreciated! Bryan tst <-

Dear R-developpers This concerns a problem I posted about half a year ago on the R-help list and to which I got some answer by Duncan Temple Lang (see below), but the basic problem still continues. Even though I managed a workaround which is sufficient for me Martin Maechler asked me to send a toy example of the problem to R-bugs. So that's what I try here. The following Makefile will not
