Neal Richardson created ARROW-6365:
--------------------------------------
Summary: [R] Should be able to coerce numeric to integer with
schema
Key: ARROW-6365
URL: https://issues.apache.org/jira/browse/ARROW-6365
Project: Apache Arrow
Issue Type: Improvement
Components: R
Reporter: Neal Richardson
Fix For: 0.15.0
R is flexible when it comes to integer vs. floating point, generally obscuring
the details inside a "numeric" class, but it knows how to make it seem like my
integer-looking data stored in a double is actually integer. This means that an
R user can think they have integers even when the underlying storage is not.
So I would have expected this to work, and indeed to be one reason I'd want to
specify a schema when creating a table:
{code:r}
> table(a = 1, schema = schema(a = int32()))
Error in Table__from_dots(dots, schema) :
Invalid: Cannot convert R vector of type REALSXP to integer Arrow array
{code}
