I am experiencing a problem trying to use a method from the bigmemory.
Specifically, I am using attach.big.matrix but the problem manifests when
trying to call attach.resource. My environment is as follows:
> sessionInfo()
R version 2.10.1 (2009-12-14)
x86_64-pc-linux-gnu
locale:
[1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C
[3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8
[5] LC_MONETARY=C LC_MESSAGES=en_US.UTF-8
[7] LC_PAPER=en_US.UTF-8 LC_NAME=C
[9] LC_ADDRESS=C LC_TELEPHONE=C
[11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C
attached base packages:
[1] stats graphics grDevices utils datasets methods base
other attached packages:
[1] bigmemory_4.2.3
loaded via a namespace (and not attached):
[1] tools_2.10.1
The generic function attach.resource has the following methods:
> showMethods("attach.resource")
Function: attach.resource (package bigmemory)
obj="big.matrix.descriptor"
obj="character"
I am trying to call the second version of the method with "character"
signature.
> attach.resource('my_big_matrix.desc')
Error in function (classes, fdef, mtable) :
unable to find an inherited method for function "attach.resource",
for
signature "list"
I would expect this to dispatch correctly as the class of the argument is
correct:
> class('my_big_matrix.desc')
[1] "character"
I suspect something may be wrong with my installation of R. It is version
2.10.1 on Ubuntu 64bit. Any help is appreciated.
