Error reading an xlsx file from Dropbox using the R package 'repmis'

问题

I need to be able to read a sheet from an xlsx workbook into R for use in a Shiny app. (I know it should be a csv file, but that is unfortunately not my decision...).(Edited to add: The file I need to read is on dropbox) I am trying to use the repmis package. The code I have tried is simply:

library('repmis')
library('xlsx')
lnk<-"https://www.dropbox.com/s/pzyt86pguko3xg6/TestBook.xlsx?dl=0"
my_data<-source_XlsxData(lnk, sheet="MainData", startRow=1)

Unfortunately I get the following error message:

Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl,  :
java.lang.IllegalArgumentException: Your InputStream was neither an OLE2 stream, nor an OOXML stream

I have no idea what it means... :|

回答1:

I think a recent update removed the ability to read data files stored on Dropbox from within R. I will go look for confirmation, and delete my comment otherwise.

Source: Ran into the same issue myself a couple of months ago

UPDATE: Confirmation of dropped support within the github package https://github.com/christophergandrud/repmis/commit/f85469f38c6f4e4a5735ecc888b4263b969d4e22
