问题 I have a dataset I'm trying to tidy up. I read in the file with read.xlsx, contained in the header is date values that I need to retain their values even when duplicated when I gather/spread the data. The data set looks like the below. The dates from excel read in as numbers (which is fine) the issue is that there can be duplicate dates (e.g. 43693) , which I need to keep their original values. Date 43693 43686 43686 43714 43693 1 Contract 111 222 333 444 555 2 Org1 NR NB NR NB P 3 Org2 P P P
