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... ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
