Hi, Gabor:
I just lost perhaps a day's work due to that very problem: I
couldn't get read.zoo to work, so I used read.table, which created
factors, because some of my numeric columns included, ", NA", which got
translated as a level " NA" (note this three character code with a space
before the NA). Then I did "as.matrix" of the data.frame that I thought
was numeric; the result was a zoo object with coredata of class
character rather than numeric.
Best Wishes,
Spencer
