How to read xls/xlsx files using ArvadosR SDK


I went through the Arvados R SDK document, but I didn’t find how excel files (.xls or .xlsx) are read in R from Arvados API? So far it seems that only .txt, .tsv, .csv, .json can be read?

I have not used it myself, but according to this, collection$readArvFile() supports reading xlsx:

Thanks! But it didn’t work for me, so I was really looking for some function similar to read.delim but to read xlsx data. Unfortunately, openxlsx or readxl function only takes file not connection
