I have generated a dataset from Qualtrics (tried the .sav and .csv options, and manually saving the .csv as .xlsx) and imported it (in the different versions) into R. When I ask R to define the objects in the tbl_df, it displays a long list of objects (including Q9021 below). When I try to get any information about individual objects (using basic commands like "class," "mode," "mean" etc.), I always get an error, e.g.:
"> class(Q9021) Error: object 'Q9021' not found"
What might be the problem here? Please help
