I had working code under R v3.2 that serialized an object, stored the
serialized object in a database, and then successfully retrieved and
hydrated that object.
I recently updated to R v3.4.1 and the same code now fails.
Here is the code in question (simplified), and the resulting error:
> zz = textConnection('tempConnection', 'wb')
> saveRDS(c("a", "b", "c"), zz, ascii = TRUE)
> serialized_obj = paste(textConnectionValue(zz), collapse='\n')
Error in gzcon(file) : 'read' not enabled for this connection
Docs haven't been much help in this case. I've tried a number of variations
but no luck. readRDS() was updated in v3.4.1, but I'm hesitant to call this
a bug without intimate knowledge of the source. Any help would be greatly
