Convert data into zoo object using Performance analytics package
Dear All,
Thanks a lot for your help. Would you please let me know if i want to read
a csv file as zoo object from my local file rather than directly from the
website, how to do that?
library(zoo)
u <- "https://faculty.washington.edu/ezivot/econ424/sbuxPrices.csv"
fmt <- "%m/%d/%Y"
With sincere regards,
