Hi Sorry for banal question How to create empty data frame with for example 30 variables without typying: data.frame(x=1,y=1....) Jarek

Hi! How to write in model's formula of type: nls(y~k/(x^n), data=data, start=list(k=1,n=1)) i.e the problem is on x^n, I(x^n) generate error thanks Jarek

Dear All! I'm looking for equivalent of Matematica function "Which" which works as follows: z = Which[x<10,0.3, 10<=x<20,0.5, 20<=x<100,1] where x is a vector I can replace it with custom function with set of ifelse but I'm looking for simpler and faster (much faster) solution best wishes Jarek

Hi I'm looking for solution or function which I can use to sample data frame, to obtain new (smaller) data frame similar to sample() function Jarek Jasiewicz

Hi I have the problem with fitting curve to data with lm and glm. When I use polynominal dependiency, fitted values from model are OK, but I cannot recive proper values when I use coefficents to caltulate this. Let me present simple example: I have simple data.frame: (dd) a: 1 2 3 4 5 6 b: 3 5 6 7 9 10 I try to fit it to model: model=glm(b~poly(a,3),data=dd) I have following data

I've been trough the R documentation for about half an hour and it's not clear to me how to do this: I need to format to character a series of integers from 1 to 1000, and I like them to look like "0001" "0002", "0059", "0123" and so on. Padded with zeroes to have four digits. Cheers! Mario. r-help-request at r-project.org wrote: > Send

I have moved from dovecot 1.x to 2.x and I have big problem with subfolders. When I'm moving subfolder with other subfolders is moving only main subfolder, without subfolders, example : mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/dbox-Mails

Hi, Today, I performed automatic updates of packages and somehow lost "class" package. I loaded a library that depended on it and got: Error: package 'class' could not be loaded In addition: Warning message: there is no package called 'class' in: library(pkg, character.only = TRUE, logical = TRUE, lib.loc = lib.loc) I tried to load it by instal-package: class (VR) and

Hi, I am looking for functions that would allow me to access raw binary data of R vectors. One way would be to use: x = (1:10)*pi writeBin(x, "temp.bin") r = readBin("temp.bin", "raw", n=length(x)*8) Other to write my own C code. Is there any other simpler way? I this message is a rewording of my yesterday message "Looking for function for Double to

Hi, I am trying to write a function to read in a whole text file as a single string ( so I can calculate its "sha1" hash function using package "digest"). I need a single string containing the whole file, and so far I was using paste(readLines(fileName), collapse = ""). Unfortunately this function gives me warnings : incomplete final line found by readLines on

Hi, Consider the following code: require(XML) xmlFile = paste( "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\n", "<mzXML xmlns=\"a\" xmlns:xsi=\"b\" xsi:schemaLocation=\"c\">\n", "<parentFile a=\"a\" b=\"b\" />\n",

Hi, I was playing with Mandelbrot sets and come up with the following code, I thought I would share: library(fields) # for tim.colors library(caTools) # for write.gif m = 400 # grid size C = complex( real=rep(seq(-1.8,0.6, length.out=m), each=m ), imag=rep(seq(-1.2,1.2, length.out=m), m ) ) C = matrix(C,m,m) Z = 0 X = array(0, c(m,m,20)) for (k in 1:20) { Z =

Hi, I need to split a string into 2 strings, with the split point defined by the last occurrence of some substring. I come up with some convoluted code to do so: str = "Chance favors the prepared mind" sub = "e" y = unlist(strsplit(str,sub)) z = cbind(paste(y[-length(y)], sub, sep="", collapse = ""), y[length(y)]); y z z[1] z[2] Is there a simpler way

Hi, I am trying to debug my code and looking for any tool to help me out with it. My main problem is with the error messages I can not figure out where they come from (what function produced them) and what do they mean. Is there such a think as list of error messages produced by R and standard R packages, and what do they mean? Or any tool to extract information which function produced the

Hi, I run into following problem. It seems to me that operation in the 3rd line should be valid. > b = matrix(as.raw(0), 8,8) > q = as.raw(1:8) > b[1,] = q Error: incompatible types in subset assignment > length(b[1,]) [1] 8 > typeof(b[1,]) [1] "raw" > length(q) [1] 8 > typeof(q) [1] "raw" Is this a bug or a "feature"?
