hello everyone

we are developing a package that has worked up until R3.0 which we just
tested.

the issue is as above .... when we call a function that works in R 2.15.2
from  R 3.0 we get an error

Error in .Call("antsImageRead", filename, pixeltype, dimension) :
  "antsImageRead" not resolved from current namespace (ANTsR)

this Error occurs when the .Call is made from within the .R function
wrapper that eases access to the C++ version of antsImageRead.

however, a direct  .Call("antsImageRead", etc. ) works as usual.

this happens for some of our functions and not others - not all are .Calls
...

i don't see a pattern to it.

a hack resolution that "works" is to source the .R files again within the R
shell.

of course, this is not a satisfying solution.

finally, if anyone cares to try to reproduce this error, here is what you
would do:


If you have CMake installed, then open R 3.0 and do:


install.packages(c("devtools", "Rcpp", "methods", "signal", "parallel",
    "timeSeries", "mFilter", "MASS", "robust", "magic", "knitr",
"pixmap", "rgl", "misc3d"))

then Clone or Pull ANTsR from this repository as follows:

$ git clone git@github.com:stnava/ANTsR.git

>From the parent directory of the new ANTsR directory, install the package
as follows:

$ R CMD INSTALL ANTsR


finally - the error can be reproduced in R 3.0 as :

library(ANTsR)
fi<-antsImageRead( getANTsRData('r16') ,2)

any help would be appreciated -

brian
