similar to: output of system() call not returned in Win98

A solution to my problem was kindly suggested by Roger Bivand, namely the list.files() function. Thanks also to Prof. Ripley.

I've run into a problem with the datetime axis generated by axis.POSIXct. It appears a similar issue was discussed in October 2003 under the subject line "datetime data and plotting" (see https://stat.ethz.ch/pipermail/r-help/2003-October/039071.html), but I wasn't able to determine whether there is a straightforward solution. The code below produces a graph with apparently

Hi: I had asterisk with RealTime database working perfectly in a RH 9.0 machine. I used the sip cache so I even had MWI working. The problem is that I decided to move to Fedora Core 3. I installed the lastets cvs version of asterisk and the RealTime addon from asterisk-addons. I at first had the problems with the kernel and the zaptel driver but all that was solved with the

Hi all, Thanks to everybody who thought on this problem, there was slight mistake in the fortran code which lead to NULL pointer allocation error, but still it surprises me that why it does not crib in the first run. The compiler I am using is absoft fortran compiler. Cheers, -Jag Jagadish Rangrej ( Statistician ) CHEO Research Institute, Ottawa, ON 613-7383951 > -----Original Message-----

I have a problem with function 'inout()' in package 'splancs' on CRAN-R Version 1.2.3 under FreeBSD4.3-STABLE. The following script produces and draws points and a polygon-surrounded area. Repeating the same script many times shows, that points on the polygon-line often, but not always, are outside of the polygon-area. library(splancs) # dataset with polygon (convex

What are some effective ways to leverage the strengths of R and Mathematica for the analysis of a single data set? More specifically, are there any functions that can assist with any of the following? 1. Calling an R function from Mathematica. 2. Calling a Mathematica function from R. 3. Using XML or another reliable data format to pass vectors, matrices, and/or lists from one environment to

Hi, I'm stumped. How can I do ftell and fseek in R? (Where ftell gives the position in the file and fseek points the file pointer to a given position.)

Hello, It is very simple question. I want to go to the parent directory and give the 'system("cd ../") commnad. But it stayes at the same dirctory as before. Do I forget to give some extra parameter to system command in this case?

Hello everybody ! I want to evaluate the goodness of the fit of a trend surface. I use the Least square methods and the function surf.ls. The I write tma3.sur3 <- surf.ls(3, x, y, z) summary(tma3.sur3) Now the question: is the Pr(>F) the probability to obtain a value of F equal or greater than the obtained one ? Is the confidence level 0.05 ? Thanks a lot for any help. Paola.

I?m tryng to use the SPDEP package in my research in the field of population genetics. My data set has the following format: - x and y : coordinates, - Z: allelic frequency in each loci (in a total of 8 locis) - this variable can assume the values 0 ; 0.5 or 1. The objective is to verify if there is a possible spatial autocorrelation structure of the allelic frequency in a population of

Hi all, i have a little pb but i don t find how i can solve it.. this is.. i have two vectors x and yn and they don t have the same length... (i suppose length(x)>length(y)) this is what i want to do. i suppose that x=c(10,1,2,3,7,9,1,4,2,11,2,10) and y=c(1,2,4,10) i want to find all the numbers of rows i of x for which x[i] exists in y ... i.e. in this case ...rep=(1,2,3,7,8,9,11,12) Best

Dear R users, I am currently writing a MCMC algorithm for spatial Poisson model. One problem which I need to solve is as follows: I have a vector X[1:J] which describes characteristics of cells of a rectangular grid. Further, for each cell I have a list of adjascent cells adj[] and the vector listing numbed of adjascent cells num[]. Thus if I want to list cells adjascent to cell i I write

Hello, I am interested in fitting a generalized nonlinear regression (gnlr) model with negative binomial errors. I have found Jim Lindsay's package that will do gnlr, but I have having trouble with the particular model I am interested in fitting. It is a threshhold model, where below a certain value of one of the parameters being fitted, the model changes. Here is a sample: Cones:

hello. I am trying to read a big file with different sections each with a different format, actually it is a map in format *.e00 of MapView. I can read the whole file with no problems from R using scan() but it takes too long, some files are 50 meg and have to be read line by line to catch the section codes. So if I do the reading from C would it be faster? if it is, how do I manage with the

Thanks to Roger for pointing out the packages spweights and sptests to me. I believe they will be quiet useful in my work. But... I can't get them to work! Firstly, I realised that a newer version of R is available. I have now downloaded and installed it. When I try to 'install packages from CRAN' I get: trying URL `http://cran.r-project.org/bin/windows/contrib/PACKAGES' unable

After installation of R into VineLinux2.1.5, I started to enjoy statistics following some instruction, and found it very useful. One of my main purpose to use R is to try spatial statistics. Since library named "spatial" has already installed, I just tried ... > library(spatial) > towns <- ppinit(test.dat) ------- test.dat ------- x,y 4,7 5,7 5,8 5,9 6,7 6,8 6,9 7,8

Dear All, Has anyone worked with linking R to both ArcView and MapInfo GIS systems? My desire is to capture object selection from GIS and pass to R and to return spatially based statistical model results from R to GIS. If both could simultaneously access the same data file this would be a bonus. My inclination is to put together some routines based on ODBC linking but thought I would seek like
