In a time series ts object, like the z1.ts below:
z1 = array(1:235)
z1.ts = ts(z1, frequency =12)
I would like to select only a certain month, for instance the "February"
data
If I transform the data to a matrix, I have the problem that 235 is not
a multiple of 12
I do not like to cut or add data, or program a loop to pick out the
correct data.
I am wondering if exist an easier way to select month data in a ts object.
Thank you a lot for your help.
