I am trying to convert some data as shown below into xts format. using as.xts I get an error about unambiguous format, but my understanding is my date column is already in the standard format.
Ex = as.xts(Ex)
Gives me error Error in as.POSIXlt.character(x, tz, ...) : character string is not in a standard unambiguous format
Or
Ex = as.xts(Ex[,-1], Ex[,1]) Error in xts(x, order.by = order.by, frequency = frequency, ...) : order.by requires an appropriate time-based object
Head of my data:
# A tibble: 6 x 3
Date A B
<date> <dbl> <dbl>

2 2013-08-12 10.3 6.38
3 2013-08-13 10.5 6.37
4 2013-08-14 10.5 6.40
