Has something changed in R that requires an update in the genetics package
by Gregory Warnes? I am using R version 2.5.0
This used to work
> summary(founders[,59])
to prove that it is a genotype class
> class(founders[,59])
[1] "genotype" "factor"
Now when I issue the command:
> summary(founders[,59])
I get:
Error in attr(retval, "which") <- which : attempt to set an attribute on
NULL
In addition: Warning message:
$ operator is deprecated for atomic vectors, returning NULL in:
x$allele.names
Clearly, I am missing something. What am I missing?
