Writing and reading a zoo object - errors

Question

I have a zoo object, prices, which, when I type class(prices), it returns “zoo.” I then create a file using:

write.zoo(prices, file = “foo”, index.name = “time”)

The resulting files looks like this:

"time" "AAPL.Adjusted" “SHY.Adjusted"
2013-05-01 60.31 84.12
2013-05-02 61.16 84.11
2013-05-03 61.77 84.08

I then try and read this file with this statement:

myData <- read.zoo(“foo”)

and I get this error:

Error in read.zoo(“foo") :
index has bad entries at data rows: 1 2 3 4

I’ve tried a number of parameter settings and nothing seems to work. Help much appreciated. Newbie

Answer 1

The file has a header line so try:

z <- read.zoo("foo", header = TRUE, check.names = FALSE)

The check.names part gives nicer looking column names but you could leave it out if that were not important.
