My computer is a pentium 4 running at 2.4 GHz. My R is 1.7.1 I have written a program in R that calls C++. The program spends most of the time in C++ ( > 90% ). R basically deals with output and input. How slower can this be compared with the program I would get from rewriting everything in C++? Thank you.

Hi, I have plotted the graph of x^2 and I would like to add to it a line that is currently outside of the plot ( the points of the line fall outside of the plot ). When I use the function 'lines' the graphics window does not became larger to show this line. Is there any way I can fix this? Also, how can I eliminate the axis from the plot? Thank you.

In "Frequently Asked Questions on R" there is a section "Debugging R from within Emacs" I suppose this is for developpers ( not useful to debug R source code ). Am I right?

Acording to the documentation in gsl "The physical row dimension tda, or trailing dimension, specifies the size of a row of the matrix as laid out in memory" I think that if I pass a matrix to C++ through .C as single ( or.double ), that is, .C ( as.single ( matrix )) then the tda is simply the number of elements of that matrix. Am I right? Thank you.

I would like my program to load variables x,y,x from a file 'myFile.r' but if this file does not exist, I want my program to create/initialize x,y,z. Does anyone know how to do this? Thank you very much. Francisco J. Molina

Is there a function like "is.there" such that is.there ( a ) returns TRUE is object 'a' is in the current environment and FALSE otherwise? Thank you. Francisco J. Molina

I am using 1.7.1 in a PC ( redhat 9, linux ) I created a subroutine in C++, mySubrutine, to be used in R. To debug this subroutine I have a main routine in C++ that calls mySubrutine. The only thing main () does is to provide mySubrutine with its arguments (this is the easiest way for me to debug subroutines written in C++ and intended to be used in R ). I also have a version of the same

I have been checking the information provided with postscript(). Acording to the manual the argument of postscript() is the name of a file with extension ps . The postscript produced by R is EPS (Encapsulated PostScript) compatible, so I tried to pass to postscript() the name of a file with extension eps. Then I included this file in a Latex document and everything worked fine. Does what I

I am calling C++ from R. I want C++ to return a vector whose length is not known when the C++ routine is called. Is it possible to do this without using R objects in the C++ routine? So far I have been using .C, but I do not see how I could use it in this case. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read
