-----------------------------------

             Summary: coerce_timestamps does not work in write_parquet in Apache arrow R package
                 Key: ARROW-9219
                 URL: https://issues.apache.org/jira/browse/ARROW-9219
             Project: Apache Arrow
          Issue Type: Bug

         Environment: macOS 10.15.5, R  4.0.0
            Reporter: Slim Bentami


i am trying to truncate timestamps to milliseconds when writing a parquet file.

with:

 

{{tutu <- as.POSIXct("2020/06/03 18:00:00",tz = "UTC")}}

if i do:

 

{{write_parquet(data.frame(tutu),"~/Downloads/tutu.test.parquet")}}

i get 1591207200000000

if i do:

 

{{write_parquet(data.frame(tutu),"~/Downloads/tutu.test.parquet", coerce_timestamps = "ms", allow_truncated_timestamps = TRUE)}}

i get the error message:

 

{{Error in parquet___ArrowWriterProperties___Builder__coerce_timestamps(unit) : 
  argument "unit" is missing, with no default}}

what am i doing wrong? thanks in advance.
