I've an XTS object, x, and I've added a column which is the sum of the other columns:
print(x$sum)shows me the sum for each row, along with the datestamp of that row. I.e.
x$sumis still an XTS object. Normally this is good, but I wanted it as a simple vector, without the dates associated. Here is how you do that:
as.vector(x$sum)Why did I want that? Simply because
summary(x$sum)uses up 7 lines, half of it being noise about the datestamps;
summary(as.vector(x$sum))is 2 lines, all signal, no noise.
