• Type: Bug

Description

This succeeds:

Array$create(1)$cast(decimal(10, 2))

but this fails:

Array$create(1, type = decimal(10, 2))

with error:

NotImplemented: Extend

because the Extend method of the RPromitiveConverter class for the Decimal type is not yet implemented.

The error is thrown here: https://github.com/apache/arrow/blob/7184c3f46981dd52c3c521b2676796e82f17da77/r/src/r_to_arrow.cpp#L601
