[R-SIG-Finance] R - Error Question for chart.Correlation(PerformanceAnalytics)

[Guy Yollin]

Interesting, I wasn't calling data(managers), I was just calling
library(PerformanceAnalytics) and then accessing the dataframe:

> head(managers)

I see that calling data(managers) first supplies the dataframe with the
expected format; thanks for the clarification.  I don't know enough
about building packages to know if this is the expected behavior or not.

Best,

Can you clarify this?  How are you loading the data?  The examples,
which are 
all run (tested) as part of the submission to CRAN, simply load the data

using:

If you use read.csv, you'll want to set row.names=1 so to capture the 
appropriate label.

Also, these data objects are now zoo objects and degrade nicely with
as.matrix 
and other similar functions.
