Dear Sir,
Thanks for your mail and help. I got this error while trying to run your
code.
sbux1.z <- read.csv.zoo(u, FUN = as.yearmon, format = fmt)
Error in read.table(file = file, header = header, sep = sep, quote =
quote, :
'file' must be a character string or connection
Thanks and Regards,
Upananda Pani

Depending on how you created df maybe your code has the column names
wrong. In any case these 4 alternatives all work. Start a fresh R
session and then copy and paste this into it.
library(zoo)
u <- "https://faculty.washington.edu/ezivot/econ424/sbuxPrices.csv"
fmt <- "%m/%d/%Y"
# 1
sbux1.z <- read.csv.zoo(u, FUN = as.yearmon, format = fmt)
# 2
df <- read.csv(u)
sbux2.z <- read.zoo(df, FUN = as.yearmon, format = fmt)
# 3
df <- read.csv(u)
names(head(df))
## [1] "Date" "Adj.Close"
sbux3.z <- zoo(df$Adj.Close, as.yearmon(df$Date, fmt))
# 4
df <- read.csv(u)
sbux4.z <- zoo(df[[2]], as.yearmon(df[[1]], fmt))

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)
Data:
numeric(0)
I will be grateful if anybody would like to guide me where i am making
mistake.
With best regards,
Upananda Pani
