R CMD check does not recognize S4 functions inside other functions?
...he sparse matrix routines in the package 'Matrix'. When these are loaded in R, they create no problems. However, when running R CMD check, I run into the following error in executing the examples in a .rd file: > DD = Matrix(diag(1,200),sparse=TRUE) > tDD = t(DD) > > fres = FitMatchOpt(coefs=coefs,which=2,pars=pars,proc) Error in t.default(DD) : argument is not a matrix Calls: FitMatchOpt -> t -> t.default Execution halted The first two lines of the function FitMatchOpt are DD = Matrix(diag(1,200),sparse=TRUE) tDD = t(DD) These were fine when given in...

Another good optimization (for PPC only, though)
Using the PPC frsqrte and fres instructions, I got the percentage time take in the smoothing code in _vp_compute_mask() down from 13.64% to 1.88% of the running time. In my local copy of Vorbis I have a fast_math.[hc] in vorbis/lib and have a _fast_sqrt() inline in fast_math.h. If anyone else wants to try it out, it follows....

...it. My reviewer has asked me to use different symbols for each of the forest types. Can anyone send me how I can do this in R in simple steps. I have used the options like ordiplot, sel and pl syntaxes that are not working for the question that I asked for.

...even in R-devel I do not see, directly, how you are using these tools (some projects include either a setup.sh or a buildconf script to standardize how the project does this.) I am quite capable of just calling the tools in sequence, but would prefer to follow your procedure. I Starting again - fresh 3.1.3, 3.2.2 and R-devel - all in 32-bit mode, for the start. The goal is a 64-bit build so that memory management will be easier. This is my "standard command for building a package" CPPFLAGS="-I/opt/buildaix/include -I/opt/include" CFLAGS="-I/opt/include -I/opt/buil...
