You haven't told us how you wrote the file, but my guess is that you used
dput(). If so, consult the help page and note it says
Deparsing an object is difficult, and not always possible. With
the default 'control = c("showAttributes")',
'dput()' attempts to
deparse in a way that is readable, but for more complex or unusual
objects, not likely to be parsed as identical to the original.
Use 'control = "all"' for the most complete deparsing;
use
'control = NULL' for the simplest deparsing, not even including
attributes.
so your problem is described right there on the help page.
And please don't sent multiple messages on the same topic: your second
message is about an inaccurate dput of the file, and not about an actual
object in R.
