Write a different tag value for every element of an xts

[xanderdunn]

Based on my experimentation with xtsAttributes and looking at the documentation, it looks like setting attributes on an xts are global attributes for all values in the matrix?

What I'd like to do is be able to set xtsAttributes(my_xts) <- (tag_key = my_tags), where nrows(my_xts) == nrows(my_tags) so that every item in my_xts has a different value for the same tag_key.

This is easy to do in influxdb-python where the column of a data frame can be specific as a tag column in the influx_write function.

Yeah, that would be great! We therefore need to parse a data.frame to influxdb's line protocol and modify influx_write.

It must be further specified, which columns are fields and which are tags (optionally, a datetime column, too)

I'm closing this issue and opening the #20
