I am a beginner and am trying to make some basic graphs for school, and every time I try to load, the following error occurs:
load("UmsatzImEinzelhandel_Quartalsdaten.xlsx")
Error: bad restore file magic number (file may be corrupted) -- no data loaded In addition: Warning message: file 'UmsatzImEinzelhandel_Quartalsdaten.xlsx' has magic number 'PK' Use of save versions prior to 2 is deprecated
I need to load a simple data table created in Excel, but it keeps popping this error message. I have tried to even recreate the whole table and it simply does not work. I don't know what I have to do. Thanks a lot for your help in advance!
