Thanks, Luke, for having a look to it.
Sure, I can give you some reproducible example -- even in two degrees of
completeness ;-): see below.
Thanks again, Peter
%-----------------------------------
(I) first example
%-----------------------------------
Just to reproduce the error, on r-devel, try:
install.packages("RobAStRDA")
require(RobAStRDA)
getFromNamespace(".RMXE", ns = "RobAStRDA")[["GEVFamily"]][["fun.N"]][[1]](1.3)
%-----------------------------------
(II) an example also giving the context
%-----------------------------------
For the "complete" story, not only the R-code needs to be given, but also the
preparation steps to produce the packages on the right R version;
so please follow steps (1)--(6) below; I am not 100% sure whether this already
gives
you all information needed for this, but if not so please let me know.
(1) create a minimal R-package "InterpolTry"
with byte-compilation on in the DESCRIPTION file
and with stats::approxfun imported in the NAMESPACE file
(2) in an R session on R-devel do
require(InterpolTry)
x <- 1:100
y <- 1:100
fun <- approxfun(x,y)
## revise the next line accordingly to your local settings
SrcRPathInterpolTry <- <path_to_(source-)R-folder_of_InterpolTry>
RdaFile <- file.path(SrcRPathInterpolTry, "sysdata.rda")
save(fun, file = RdaFile)
tools::resaveRdaFiles(RdaFile)
(3) re-build package InterpolTry and re-install it
(4) create a minimal R package "UseInterpolTry", again
with byte-compilation on in the DESCRIPTION file
and with stats::approxfun and package "InterpolTry"
imported in the NAMESPACE file
(5) in the R folder of R package "UseInterpolTry" write a function
useInterpolFct() which goes like this
useInterpolFct <- function(x){
fun <- getFromNamespace("fun", ns = "InterpolTry")
fun(x)
}
export this function in the namespace and create an .Rd file to it
(6) (re-)build package "UseInterpolTry" and (re-)install it and try
require(UseInterpolTry)
useInterpolFct(5)
Steps (1)--(6) work with R-3.1.3, but no longer with R-devel.
