Dear R People: I am reading in a file via read.table. Is there a way to bring in the time that the file was created, please? Thanks, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: erinm.hodgess at gmail.com

You could write a wee wrapper and give the file an attribute. For
example,
copy <- function (file = "clipboard", sep = "\t",
na.strings = c("NA",
"*"), as.is = T, ...)
{
myX <- read.table(file, sep = sep, na.strings = na.strings,
as.is = as.is, ...)
attr(myX, "copy time") <- Sys.time()
myX
}
I did this some time ago, but I must admit that I find it of limited
value.

Peter, that is assigning the time of creation of the object name.
I think Erin might be looking for the file.info function, see ?file.info .
