r – How to overcome error:attempt to set colnames on an object with less than two dimension in xts object

You probably want:

q <- data.frame(100,200,200,200,200,200)
colnames(q) <- colnames(SPY)
q <- xts(q, as.Date(2016-01-26))
#            SPY.Open SPY.High SPY.Low SPY.Close SPY.Volume SPY.Adjusted
# 2016-01-26      100      200     200       200        200          200

class(SPY)
# [1] xts zoo
class(q)
# [1] xts zoo

tail(rbind(SPY, q))
#            SPY.Open SPY.High SPY.Low SPY.Close SPY.Volume SPY.Adjusted
# 2016-01-19   189.96   190.11  186.20    188.06  190196000       188.06
