Hi,
I am new in writing R extension.
I read the "Writing R Extensions", and search online but just cannot
find the answer.
I am trying to add c-code, which depend on GSL C library, into my R
package.
I am using Max OS-X 10.4.3, powerpc-apple-darwin8-gcc-4.0.1
I begin wtih package.skeleton, and then add my c file into folder src
and then add file Makevars:
PKG_LIBS=-lgsl -lgslcblas -lm
In the zzz.R file, I add the function .First.lib:
.First.lib <- function(lib, pkg) {
library.dynam("anovaGSL", pkg, lib)
}
I think these two things are enough. then I just run R CMD check
anovaGSL (my package name)
followed is the error message:
Error: .First.lib failed for 'anovaGSL'
Call sequence:
2: stop(gettextf(".First.lib failed for '%s'", libraryPkgName(package)),
domain = NA)
1: library(package, lib.loc = lib.loc, character.only = TRUE, verbose
= FALSE)
Execution halted
See section 'Generic functions and methods' of the 'Writing R
Extensions'
manual.

Execution halted
In R, the argument of a replacement function which corresponds to the
right
hand side must be named 'value'.

appreciate any help!!!
