TimeSeries Data Manipulation

["Chen,Sichong" <sichong.chen@postgrad.manchester.ac.uk>]

Dear Users

I have a silly question. How can I change a Time Series vector or matrix into a non-Time Series vector or matrix?

My problem is that I have one time series vector A (280*1) and one time series matrix B (280*3), which has the same time period. What I want to do is to combine these two together and create a new matrix (280*4) like rbind for the no-time series dataframe. Since rbind does not work for time series data, I tried to use B[,4] = A, but fails if it is, which says “Problem in x[, j] <- value: Array subscript (2) out of bounds, should be at most 1”. So I want to convert A, B back to non-time series object, combine and convert again.

Do you have some idea what’s going wrong in my problem. I though it should not be that difficult and complicated to add one more column to a time series object.

Many thanks,
