Dear all, I'm trying to use the as a standalone package the nmath sources. In R-1.4.1/src/nmath/standalone, in linux operating system I made 'make shared' to obtain libRmath.so. then I copied the dir standalone, where there is libRmath.so in /usr/local. I tried to compile test.c with cc test.c but I obtain this error message /tmp/ccsTxu7U.o: In function `main':

Dearl all, I have to fit a function y = f(x1, x2) to data experiemntal data describing the measured behavior of y. x1 and x2 are the independent variables. Could you suggest me wich R package can I use for this purpose? Thanks, Paola. -- *Paola Lecca, PhD* *The Microsoft Research - University of Trento* *Centre for Computational and Systems Biology* *Piazza Manci 17 38123 Povo/Trento,

Dear all, I tried to use nls, but I got the following error Error in numericDeriv(form[[3L]], names(ind), env) : Missing value or an infinity produced when evaluating the model Any suggestion? Thanks, Paola. The code I wrote is Data_pp2_mrna <- data.frame( p1 = protein_1, p6 = protein_6, pp2_mrna

Hello to everybody ! I don't have a question directly connected with R, but it takes starting point from the use of the R function Krig for kriging interpolation and from the idea of making a different implemetation of the function for my purposes. Doas anyone know where can I find free C or C++ codes of kriging ? As always, thanks a lot in advance, Paola.

Dear R users, I'm trying to fit a set an ODE to an experimental time series. In the attachment you find the R code I wrote using modFit and modCost of FME package and the file of the time series. When I run summary(Fit) I obtain this error message, and the values of the parameters are equal to the initial guesses I gave to them. The problem is not due to the fact that I have only one

Hi everybody, I want to download the spatial library but I don't find it at the CRAN list package. Where can I find the package ? I have to download it to use the function correlogram.

Dear all, I used modFit of the package FME to fit a set of ODE to a ste of eperiemntal data. The summary of this fit give me the following error > summary(Fit) Residual standard error: 984.1 on 452 degrees of freedom Error in cov2cor(x$cov.unscaled) : 'V' is not a square numeric matrix In addition: Warning message: In summary.modFit(Fit) : Cannot estimate covariance; system is

Thanks for all the helpful responses. I include the data file and the syntax file for reference. Again, if I use the fields function, as is, I get the message: Error in svd(tempM) : error 159 in dsvdc using traceback, I get: > traceback() 4: stop(paste("error ", z$info, " in dsvdc")) 3: svd(tempM) 2: Krig(x, Y, cov.function = rad.cov, m = m, decomp = decomp,

Greetings, Quick Summary: How does R function non-interactively? I can't print graphics to an X11 window. I set up what appears to be called a "noninteractive" R session using the Perl code at the end of this message. Everthing seems to work fine as written. I get a nice postscript file with my graphics. However, I would like to display X11 R-graphics for the Perl-script

Hello, I was wondering whether anyone out there knows of the solution to a problem that I'm having with the Fields package. I am getting the error message when I try and run the fields function tps (thin plate splines). Namely, for two different sets of variables, I get: > bout <- Tps( bvolcap, bdsm) Error in svd(tempM) : error 159 in dsvdc > wout <- Tps( wvolcap, wdsm)

Hi ! is there a package in R dedicated to the signal analysis ? I'm searching for statistical methods for the signal extraction from background in a digital image. Does R have a package to perform this kind of analysis ? Thanks a lot, Paola. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Hi ! I have again problem with nmath standalone sources package. Following the suggestion of Reid, I did control that /usr/local, in which I copied the dir standalone, is listed in /etc/ld.so.conf. However, because of my big ignorance, I don't understand how I have to do the linkage to Rmath during the compilation of a source. What does it mean: "and link against -lRmath" in

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.

Hi ! Sorry for my ignorance. I have two questions: 1) which is in R the function to make a covariogram of spatial data ? 2) does anyone know if there exist the possibility in R of performing kriging with an arbitrary covariance function ? If I have well understood the Krig procedure offers only three possibilities (expcov, gauscov and sphercov) that are the common models for stationary and

I noticed some odd behavior when I transpose a data frame containing NA's. It seems to cast all the elements as "character" including the NA's. Bug? > t(data.frame(x=1:10,y=1:10,z=rep(NA,10))) 1 2 3 4 5 6 7 8 9 10 x " 1" " 2" " 3" " 4" " 5" " 6"

Hi, I have a 4 column file (long/lat/elev/variable) and I tried to fit the values of my variable to the XYZ space using Tps and I keep getting the following message: Warning messages: 1: GCV search gives a minumum at the endpoints of the grid search in: Krig.find.gcvmin(info, lambda.grid, gcv.grid$GCV, Krig.fgcv, 2: GCV search gives a minumum at the endpoints of the grid search in:

I just tried to batch-start rgui.exe (not rterm.exe) in a way, that it read.table()s data from a file with changing filename. As I understand no command line parameters are available for that, so instead I tried to pass the filename to an approbriate .RProfile, which works roughly, BUT ## this is my %R_USER%\.RProfile im <- read.table("d:/temp/im/temp.csv", header=TRUE,

Dear all, I have a strange problem with levelplot of lattice library. When I launch from R a script in which there is the command levelplot(z~x*y, ...) the device with plot is not visualized. Other commands for graphycs, like plot visualize the graphycs. Why ? What hava I to do ?

Greetings, I'm having trouble finding a simple way to calculate a weighted histogram where there may be zero raw counts in a given interval. Given equal-length vectors of data 'data' and weights 'w', and breaks (intervals) for the histogram, I calculate a weighted histogram as follows (see MASS's 'truehist' for an unweighted histogram): bin <- cut(data,

Hi ! 1) First question. Excuse me for trouble with the same question. I still have problems with the compilation of test.c in src/nmath/standalone. I did follow the instructions you gave me but I still receive this message [root at my standalone]# cc -o test test.c -L/usr/local -lRmath /usr/local/libRmath.so: undefined reference to `log' /usr/local/libRmath.so: undefined reference to
