Export the data into Excel by using R language code, this is working in desktop level not in PBI Service

Hi , I have created one report, which can export the data into XLSX file based on the users selection values.This i had implemented using R language code by installing "openxlsx" package available. This feature is working fine in Power BI desktop, but the same is not working in power bi service. Once if we get the "openxlsx" package supports to run the R code in PBI service then it could run smoothly. Could you please look into this feature
