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?

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 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

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':

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

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

Dear all, I'm a beginner in spatial regression, therefore, excuse me in advance for the stupid question. I'm using the function Tps of field library. As I read in help, the assumed model for this regression is additive Y = f(X) + e where f(X) is a d dimensional surface. I have understood that d in not an argument to specify in Tps(x, Y, ...). How can I obtain d ? Thanks a lot.

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

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 ?

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

Dear all, I'm trying to fit the following function slope_pp3_mrna = ( (k3 * v3_K_d *p1^v3_h) / ( (v3_Kd^v3_h) + p2^v3_h ) ) * ( 1/(1 + (p2/v4_Kd)^v4_h) ) - pp3_mrna to this experimental data in the datafraeme "Data_pp3_mrna" (see it at the end of this e-mail) I'm using the nls function in the following code.
