[R] (no subject)

I currently have an instance of R running on Solaris 8 Version 2.2.0 (2005-10-06 r35749)

Package: its Version: 1.0.9

Package: Hmisc Version: 3.0-1  

I decided to build a new install on Linux RedHat As4.0 32 Bit running R version 2.4.0 (2006-10-03)

Package: its Version: 1.1.4

Package: Hmisc Version: 3.1-1

Package: chron Version: 2.3-8  

I am using the library(its) on both machines and one of the functions I have been using for a long time is quantile to determine the 99% value for a given days data set.  

This works fine in the old instance of R but is not working on the new build. The only diferrence I see is the library(its) requires library(chron) to be installed on the newer version but not on the original instance.  

I read in a comma delimited file like the snippet below:

2006-10-16 09:00:01,1.01,23.23,1.98,0.99,1.98,10.89,2.00,0

2006-10-16 09:00:02,1.00,28.00,0,0,1.01,12.00,2.94,0

2006-10-16 09:00:03,1.00,24.00,0,0,1.98,18.00,2.00,0

2006-10-16 09:00:04,1.00,30.69,0,0.99,1.01,12.00,1.01,0

2006-10-16 09:00:05,2.00,26.00,0,0,1.98,15.00,1.98,0

2006-10-16 09:00:06,1.98,25.25,0,0,1.00,12.00,0,0


To get the information I need I run the following:


its.format("%Y-%m-%d %H:%M:%S")





On the older version it returns the proper values, but on the new install I get the following error:

> quantile(x[,1],c(.99))

Error in validObject(.Object) : invalid class "its" object: Dates must be non-decreasing  

Also what is interesting is when I type

I get.

An object of class its

... then towards the end of the data I get the following..

2006-10-16 09:01:50 0.99

2006-10-16 09:01:51 1.00

Slot "dates":

 [1] "2006-10-16 09:00:02 EDT" "2006-10-16 09:00:03 EDT"  [3] "2006-10-16 09:00:04 EDT" "2006-10-16 09:00:05 EDT"  [5] "2006-10-16 09:00:06 EDT" "2006-10-16 09:00:08 EDT"     I am not sure where the Slot "dates" is coming from.  

If anyone could help it would greatly appreciated.  

Thanks in advance.
