Convert data into zoo object using Performance analytics package

Dear All,

While i am trying convert data frame object to zoo object I am
getting numeric(0) error in performance analytics package.

The source code i am using from this website to learn r in finance:
https://faculty.washington.edu/ezivot/econ424/returnCalculations.r

# create zoo objects from data.frame objects
dates.sbux = as.yearmon(sbux.df$Date, format="%m/%d/%Y")
dates.msft = as.yearmon(msft.df$Date, format="%m/%d/%Y")
sbux.z = zoo(x=sbux.df$Adj.Close, order.by=dates.sbux)
msft.z = zoo(x=msft.df$Adj.Close, order.by=dates.msft)
class(sbux.z)
head(sbux.z)

head(sbux.z)

Data:
numeric(0)

I will be grateful if anybody would like to guide me where i am making the
mistake.

With best regards,
Upananda Pani
