similar to: Need some help at interfacing R with Fortran-90

I have tried to compile the working Fortran-90 routines (see attachment) to interface them with R. The compiler automatically caled by R CMD command line prints a bunch of error messages (as follows). I think I'm better off translating the Fortran implementation into R ... which is what I hoped I could avoid. Maura host705:Desktop mauede$ R CMD SHLIB ford.f90 gfortran -arch i386

I am reading the manual sections illustrating how to call a Fortran subroutine from R. I feel uneasy at the explicit statement about ".Fortran" interface working with Fortran 77. I would like to call a Fortran-90 subroutine from my R script. Is that supported at all ? Thank you, Maura tutti i telefonini TIM! [[alternative HTML version deleted]]

I have some code in Fortran-90 that outperforms my R implementation of the same algorithm (in terms of speed). I wonder whether it is possible to interface R with Fortran-90. that is would like to call a Fortran routine from my R script, passing to the Fortran routine some real numbers array, some scalar real numbers, and an integer number . I have no idea how to do that because Fortran is a

I noticed taht R cannot understand certain Fortran real constant formats. For instance: c14 <- as.double( 7.785205408500864D-02) Error: unexpected symbol in " c14 <- as.double( 7.785205408500864D" The above "D" is used in Fortran language to indicate the memory starage mode. That is for instructing Fortran compiler to store such a REAL constant in DOUBLE

I have attached a text file representing the centralized amplitude of a signal, sampled at 30Hz, whose length N = 6922 My goal is to remove the trend. I am using package "simsalabim". I ran command decompSSA with L = length(Amps)/5 The reason is that I have SSA/MTM toolkit running in Mac/OS. SSA/MTM documentation, relative to SSA, recommends that N/10 <= L <= N/5.

I have upgraded R and am currently running the following version: R version 2.10.1 Patched (2010-02-20 r51163) Copyright (C) 2010 The R Foundation for Statistical Computing ISBN 3-900051-07-0 The characteristics of my system are the following: OS: Linux 2.6.27.29-0.1-default x86_64 Current user: mauede@linux-326k System: openSUSE 11.1 (x86_64) KDE: 4.1.3 (KDE 4.1.3) "release

I wonder whether it is possible in R to generate color-coded 3D plots, like the attached example. Basically a function f(x,y) (the 3rd dimension) is rendered through colors intensities. The side color-bar is a guide to the interpretation of the plot. Thank you very much, Maura e tutti i telefonini TIM! Vai su e tutti i telefonini TIM! Vai su

I have recently replaced R-2.9.0 with R-2.10.1 Patched. Apparently the installation completed successfully but right now I realized that the on-line help does not work any more. When I type "?<R-command>" a message pops up warning that "Help will not be available. Path not found" ... regardless of the R-command. How can I get back R on-line man pages ? Thank you very

I deal with mono-channel breathing signals sampled at 30[Hz] which are non-linear and non-stationary. My goal is to classify the signals according to common breathing patterns Trend remotion is necessary for cluster analysis but quite challenging. In fact, quasi-periodic patterns that span a number of consecutive breathing cycles should not be naively removed as they carry a lot of useful

Is there a way to force the number of ticks along an axis ? I read the on-line documentation and tried many combinations of all available parameters from functions par(), axTicks(), axis(), plot() ... but no luck !

Can biomaRt connect to data base "http://mirecords.umn.edu" or a branch of it ... for instance the validated miRNAs list ..? Thank you very much. Maura tutti i telefonini TIM! [[alternative HTML version deleted]]

Is there any R package that implements the same capability of MatLab toolbox called SimBiology ? We are expecially interested in protein-protein interactions and network analysis. As far as I know SimBiology implements a system of ODEs reflecting the kinetic chemical reactions. We would be more interested in stochastic simulations. Thank you in advance.

here is the message I get upon trying to upgrade R from the provided RPM package for SuSE 11.1 (http://cran.r-project.org): #### YaST2 conflicts list - generated 2010-02-15 14:00:50 #### nothing provides libreadline.so.6()(64bit) needed by R-patched-2.10.1-50.1.x86_64 [ ] do not install R-patched-2.10.1-50.1.x86_64 #### YaST2 conflicts list END ### I searched for the requested library

I wonder whether R provides an interface to access miRecords data. Particularly, I am looking for extracting humans miRNA and target genes sequences. All such information is stored in there in a set of structured web site pages (http://mirecords.umn.edu/miRecords) I would greatly appreciate any suggestion even about other data bases from where it is possible to get the same sort of data. I had a

Thank you for your prompt answer. The breathing signal observations are the amplitude values as a function of time and phase. According to our model the hidden states are the different breathing types. Subjects, whose respiratiion process is regular, are likely to breathe, keeping the same cycle pattern/type, for many consecutive cycles. therefore dwelling in the same hidden state. The more

I have the following vector of strings (shown only the first 3 elements) > desc[1:3] [1] "hsa-let-7a MIMAT0000062 Homo sapiens let-7a" [2] "hsa-let-7a* MIMAT0004481 Homo sapiens let-7a*" [3] "hsa-let-7a-2* MIMAT0010195 Homo sapiens let-7a-2*" > is.vector(desc) [1] TRUE > A <- unlist(strsplit(desc[1:3], " ")) > A [1]

Hi again, Is there any documenation on interfacing R with Fortran 90/95? Or a small example...? I'm mostly interested in passing matrices as dummy arrays in Fortran 95. For example, I would like to be able to call from R a routine having a declaration such as subroutine F(x,....) double, dimension(:,:), intent(inout) :: x ..... end subroutine F Does somebody have any experience in

After some headache with debugging my script, I finally isolated the problem taht I am going to illustrate in the following example. I expected matrix nrow to decrease consistently till 1. Instead, when the matrix is left with one row only, its nrow jumps to 2 because the matrix gets transposed. How come ? Thank you, Maura > B <- c(1,2) > B <- rbind(B,c(3,4)) > B <-
