I am having some difficulty understanding the implication of lazy evaluation mixed with DUP=F in a .Fortran call. In qr.qty from base DUP is not used as an argument so defaults to T. I am calling qr.qty with a very large array and would like to set DUP=F in the .Fortran call so that qr.qty would be defined as copied below. Is there some risk that a variable used as the argument in the original

The man page for se.contrast, when describing the contrast.obj parameter, states that "Multiple contrasts should be specified by a matrix as returned by contrasts." When doing an unbalanced single factor ANOVA, using a contrast.obj as returned by contrasts results in the following error from qr.qty when se.contrast is called: Error in qr.qty(object$qr, contrast) : qr and y must have

Hi all, Regular and avid readers of this column will know that Don Driscoll and I have recently posted two messages requesting assistance concerning an apparent failure of "se.contrast" to produce an se for a contrast. So far, an ominous silence rings in our ears, but read on Gentle Reader, and see if even the machinations of "debug" doesn't stimulate you to respond with a

Professor Ripley, Following your advice, I am now using an updated version of gcc (4.0.2 to be exact) as well as a true fortran compiler (XL Fortran Compiler v10.1.0.0 from IBM). I am still experiencing difficulty in running "make" after a successful "configure". Any additional insight you could provide would be greatly appreciated. Output of make is as follows: Running

Can anyone help? I am trying to install R-0.62.2 on a Sun with OS 5.6 (Solaris 2.6), and gcc/f77. Unfortunatley the simple commands ./configure --prefix=/opt/R make did not work, complaining when building help/docs. It claims to have problems perl (which has worked fine so far) but in practice it is not only a documentation problem: if I force "make install" and run R, then it

Hello, I've allways had some problems compiling R (R-62.x and R-63.x) on a AIX 4.2.1 System to the end: make produces following output: ... ... mkdir ../../../library/eda/R ld: 0711-327 WARNING: Entry point not found: __start ld: 0711-244 ERROR: No csects or exported symbols have been saved. gnumake[4]: *** [eda.so] Error 8 gnumake[3]: *** [all] Error 1 gnumake[2]: *** [R] Error 1 gnumake[1]:

Hello, I am trying to compile R using the Sun WorkShop 6.0 (Forte) compilers. I don't think I am having a problem with the compilers, but instead with figuring out how to modify the R configuration to use non-Gnu compilers. I found in your documentation that one should modify the config.site file to change compilers, compiler flags, library paths, etc. I made modifications in this file,
