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
