Dear list,
We have encountered problems with the package mvbutils while creating (or
reading from disk) timeSeries objects. Below is a very simple example of the
problem. We are using R 2.12 in a PC running Windows 7 64-bit Professional.
-----------
library(timeSeries)
cv1 <- as.character(as.Date(1:10, origin = "1970-01-01"))
ts1 = timeSeries(1:10, cv1, units = NULL)
print(ts1)
library(mvbutils)
ts2 = timeSeries(1:10, cv1, units = NULL)
print(ts2)
print(ts1) # Both objects have problems
--------------
This is the error message generated when printing the timeSeries after loading
mvbutils:
Error in validObject(.Object) :
invalid class "timeDate" object: 1: invalid object for slot "Data"
in class "timeDate": got class "POSIXt", should be or extend class "POSIXct"
invalid class "timeDate" object: 2: invalid object for slot "Data" in class
"timeDate": got class "POSIXct", should be or extend class "POSIXct"
The problem does not happen in other versions of R.
Any help would be appreciated.
Thanks in advance,
