Jonathan Keane created ARROW-14428:
--------------------------------------
Summary: [R] Allow me to write_parquet() from an arrow_dplyr_query
Key: ARROW-14428
URL: https://issues.apache.org/jira/browse/ARROW-14428
Project: Apache Arrow
Issue Type: Bug
Components: R
Reporter: Jonathan Keane
Right now, I can:
{code}
ds <- open_dataset("some.parquet")
ds %>%
mutate(
o_orderdate = cast(o_orderdate, date32())
) %>%
write_dataset(path = "new.parquet")
{code}
but I can't:
{code}
tab <- read_parquet("some.parquet", as_data_frame = FALSE)
tab %>%
mutate(
o_orderdate = cast(o_orderdate, date32())
) %>%
write_parquet("new.parquet")
{code}
In this case, I can cast the column as a separate command and then
{{write_parquet()}} after, but it would be nice to be able to us
`write_parquet()` in a pipeline.
