Description

For example, retrieving the object stored with the script https://repository.dataone.org/software/allsoftware/demos/r-demo-EAB-2012/d1_client_r_demo03-1.R, the retrieved object has the $date column classified as text, not date. For this column, an as.Date() coercion addresses the problem. However, the $id column isn't right. Run https://repository.dataone.org/software/allsoftware/demos/r-demo-EAB-2012/d1_client_r_demo3-retrieve.R and compare the summary of SeedPred and d1_SeedPred. This may be something best addressed as documentation, but I'm recording the issue to track it to whatever resolution makes sense and to consider writing a test to use as part of the package.

For this to work, we need much more complete support for metadata creation and parsing. The asDataFrame methods would then use the metadata available with objects to properly coerce variables to the right types in R before handing over control to the user. I am changing this to a feature request, as this functionality has not yet been implemented, but would be desirable.
