Hi everybody,

I'm working on Mac OS X and R-2.1.0 (by the way, sorry for the multiple 
emails last time, had a technical problem, and thanks for the constructive 
comments.)

I have a .R function which calls a .C function.  The R function's name is 
K_MEANSR.R and the other is K_MEANSC.C.

I compile it with 'R CMD SHLIB K_MEANSC.C' in the terminal.  I get both .so 
and .o files.

I use the function

 > dyn.load ('K_MEANSC.so')

with no error.  We can, I believe, see here that it is loaded:


 > getLoadedDLLs()
                                                                                 Filename
base 
base
grDevices 
/Library/Frameworks/R.framework/Resources/library/grDevices/libs/grDevices.so
stats 
/Library/Frameworks/R.framework/Resources/library/stats/libs/stats.so
methods 
/Library/Frameworks/R.framework/Resources/library/methods/libs/methods.so
K_MEANSC 
/Users/admin/Desktop/Marie/Marie_labo_29_juin/K-means_versions/MAC/K_MEANSC.so
R_X11 
/Library/Frameworks/R.framework/Resources/modules/R_X11.so
           Dynamic.Lookup
base               FALSE
grDevices          FALSE
stats              FALSE
methods            FALSE
K_MEANSC            TRUE
R_X11               TRUE


I then source the R code:

 > source(file.choose())

Construct a matrix that I will use for the analysis:

 > tab<-c(1,1,3,4,6,6,3,5,7,67,5,6,65,3,5,1,5,42,3,567,6,4,7,7)
 > tab<-matrix(tab,6,4)

And try to use the function:
 > K_MEANSR(tab,centers=c(2,4))
[1] "AA"
[1] "AAA"
[1] "A"
[1] "B"
Error in .C("K_MEANSC", xrows = as.integer(xrows), xcols = 
as.integer(xcols),  :
         "C" function name not in load table

Everything that is printed on the screen is correct, but why does it says 
that 'K_MEANSC' function is not in load table??? It then just stops at that 
stage of the .R function.

Thank you all for your time,
Marie-Hélène
