Hello world, I am actually trying to transfer a lecture from Statistica to R and I ran into problems with spectral analysis, I think I just don't get it 8-( (The posting from "FFT, frequs, magnitudes, phases" from 2005 did not enlighten me) As a starter for the students I have a 10year data set of air temperature with daily values and I try to get a periodogram where the annual

Hello world, I have a very strange update problem: this night I upgraded from 3.0.5 to 3.0.6 (debian unstable) and the system broke completely with very strange errors (I did not change anything to smb.conf) - win98 users can log in, copy and everything - xp users can log in, they see the shares but they cannot access the files (read error in xp). I have tested it with Xp-Prof SP1 und SP2

Hello world, short question: is there a possibility to get a list of arguments of a function *with* variable/parameter types? formals() gives me the names of the parameters, but says nothing about the parameter type it expects (I know I can always use the help function). I would like somthing like $x: vector or data.frame... Thanks in advance... Georg -- Georg Hoermann, Fachabteilung

If _you_ were asked to give a 40 minute dog and pony show about R for a group of scientists ranging from physicists to geographers what would you put in? These people want to know what R can do. I'm thinking about something like: A. Overview B. data structures C. arithmetic and manipulation D. reading data E. linear models using glm F. graphics G. programming H. other tricks like rpart or

Dear Michael, I was looking up the status of the cran2deb effort and notice that you now have a PPA where new packages are landing and being built for Ubuntu. It looks like this is still a work in progress, but is already a fantastic resource for me and I hope it is something that you can continue to operate. I'm now installing many of these packages but some things I need are missing.

Dear R users, Probably, this is quite a simpe question, but I do not find the proper way to obtain want I need. To explain the problem, I constructed a simple example. Suppose I have the following function: try1<-function(x){ y<-x[1:2] z<-x[3:4] y[1]*(z[1]+z[2])+y[2]*(z[1]+z[2]) } This function will be part of a for loop. This is what I like to obtain for every k: if k=2

Dear all, I have a character string object: > chara [1] "The name of first slot" and a list object: > class( try1) [1] "list" what I want to do is to use the chara as a slot's name of "try1". Of course I could do it like: > try1$"The name of first slot" <- matrix("", 3, 4) to create a slot of 3x4 matrix with the name

Hi: Goal: use R to turn a matrix of 1's and 0's into a corresponding image (e.g. png) of black and white pixels. Why R: Yes, I can do this more efficiently and precisely with a perl module like Image::PBM. Been there, done that many times, etc. (Just humor me. I'm trying to do this with R for a number of reasons.) Problem:

Dear all, I'd like to change a point pattern to a grid of cells and use one of the variables as the output. e.g. The point pattern is of a window of (500*500) and several features such as pH, SoilType etc. I like to divide it into a grid with cell size 5*5, and use the mean of the point values falling inside the cell as the output. Is there any package in R working with this? Thanks in

Hi, I have a line such as: myline <- " 0.100000 1.5000 0.6000 538 0.369404" and I would like to put the numbers into a vector. Some combination of tabs and spaces occur between the numbers. I tried: try1 <- strsplit(myline,"[[:blank:]]+") > try1 [[1]] [1] "" "0.100000" "1.5000"

Hello to everyone, I have 2 problems and would be very pleased if anyone can help me: 1) When I use the package "systemfit" for SUR regressions, I get two different variance-covariance matrices when I firstly do the SUR regression ("The covariance matrix of the residuals used for estimation") and secondly do the OLS regressions. In the manual for "systemfit" on page

Hi, I have a vector, which contains both strings and numbers, e.g. > foo <- c("str1",1234,"str2",0.9876) I want to know if a distinct element of the vector is a string or a number and took "is.numeric", but > is.numeric(foo[2]) [1] FALSE because R treats the numbers in a mixed vectors as strings: > foo [1] "str1" "1234"

Hi, I have a dataframe (say myData) and want to get a list (say myList) that contains a matrix for each row of the dataframe myData. These matrices are calculated based on the corresponding row of myData. Using a for()-loop to do this is very slow. Thus, I tried to use apply(). However, afaik apply() does only return a list if the matrices have different dimensions, while my matrices have
