I have an excel spreadsheet that has different date formats. R reads in the dates correctly when they're formatted as m/dd/yy, but when they're m/d/yy, it reads them as a code like this: 36251.
To fix it, I found this, which seems useful, but it is only for one date and I have multiple.
How to convert Excel date format to proper date in R
This was what was suggested:
as.Date(42705, origin = "1899-12-30")
So I tried this:
stockindices0$Date <- as.Date(stockindices0$Date , origin = "12-30-99")
but got the error:
Error in charToDate(x) :
character string is not in a standard unambiguous format
I also tried it with the year as 1899 with no success.
