Description

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.
