zoo's na.locf function not filling fields with R script in Power Query Editor

I'm trying to use the zoo package's na.locf() function to fill missing values in adjacent rows. It works when I run it in RStudio, but it does not work in PowerBI. Here's an abridged version of the R...

Hi rlu,

I am not familiar on R script, I will discuss this with outhers and try to reproduce this in my environment. I will inform you as soon as I get it 

In addition, if you want to fill it up, why not use M code to achieve this goal

You could replace empty cell by null, then click Fill->down

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcjQ0MjYxNVPSUXIEYkMgDstMLXfJTy7NTc0rAQkZ6BsZ6RsZGFoqxeoMPvVICl0rUpNLS1KDUxOLkjMwVTpZWpibmZoQbTKp6ol0SSwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [MetaGuid = _t, User = _t, Serial = _t, Action = _t, ClientTime_clean = _t]),
    #"Replaced Value" = Table.ReplaceValue(Source,"",null,Replacer.ReplaceValue,{"MetaGuid"}),
    #"Filled Down" = Table.FillDown(#"Replaced Value",{"MetaGuid"})
in
    #"Filled Down"

Thanks for your understanding and support.

Best Regards,
Zoe Zhi

Thanks for your response Zoe. I'm looking to maintain just one data munging pipeline as I use the same R script for offline analysis as well and wanted to use the same script to turn on a PowerBI dashboard to monitor metrics. Thus, M code will not be beneficial for me.
