Hi everyone,

I want to extract data from a data set according to dates specified in a
vector. I have created a blank matrix with row names (dates) that I want to
extract from the full data set. I have then performed a merge to try to o/p
rows corresponding to common dates to a results matrix, but the operation
did not fill the results matrix. Coulc anyone offer any advice to assist
with this operation?
