Thank you very much for your response. I think I found the offending code.
It's somewhere in here.
setClass("timeSeries",
representation( Data = "matrix", positions = "character",
format = "character", FinCenter = "character",
units = "character", recordIDs = "data.frame",
title = "character", documentation = "character"),
prototype = list(
Data = matrix(NA, dimnames = list("31-Dec-2006", "timeSeries")),
positions = "31-Dec-2006",
format = "%d-%b-%Y",
FinCenter = myFinCenter(),
units = "Series",
recordIDs = data.frame(),
title = "Time Series Object",
documentation = paste("Created at",
myFinCenter(),
now()@Data)
)
)
myFinCenter <- function() return("London")
Funny enough...this worked in R-2.2.1 but doesn't work in R>2.2.1
