Issue is on Stack Overflow with example code - Roland suggested I table issue here. Please see [http://stackoverflow.com/questions/34809554/r-xts-and-data-table-and-idate]

When I set dates with IDate (integer dates), I then get errors when looking at the table after an xts conversion with this error message:

Error in index.xts(x[1, ]) : unsupported ‘indexClass’ indexing type: IDate.

so with date as IDate in the data table:

dt.xts <- as.xts.data.table(dt) # seems to work okay but...
str(dt.xts) # gives indexing type error above

R3.2.2. versions: xts: 0.9-7 zoo: 1/7-12 data.table: 1.9.6

    as.xts.data.table support only POSIXct and Date classes at the moment. IDate could be supported without much hassle. IDateTime on the other hand is stored as 2 columns, so would not fit into current assumption that first data.table column is used as xts index.

    Likely to be affected by zoo issue with masking as.Date.IDate.
    To test when #1500 resolved.
