Hi everybody,
I've recently write my first R package and when I run :
R CMD check myPackage
I got the following message :
* Installing *source* package 'myPackage' ...
** R
** save image
Error in exists(x, envir, mode, inherits) :
invalid first argument
Error: unable to load R code in package 'myPackage'
Execution halted
ERROR: execution of package source for 'myPackage' failed
** Removing '/home/dmahieux/svn/microarray/src/package.Rcheck/myPackage'
In this package, I've 2 classes :
- a virtual one : MArrayExperiment
- a second which extend the first one : AffyExperiment.
I think that the problem is when building AffyExperiment , the
MArrayExperiment is not yet known and so the exists function is aborded.
Is there a special trick to tell that the MArrayExperiment class is
present in my package ?
Sincerely...
