[R] time attribute from a file

[Erik Iverson]

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 .

Tena koe Erin

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.

HTH ....
