I suppose it's conceivable that your object named "object" has some
non-standard character(s) in it that cause the code underlying cat()
to do something weird. For example,
cat('abcdef','\r','\n')
bcdef
Appears to truncate the first character.
Basic debugging suggests breaking down the problem expression into
its components in the hopes that the problem will manifest itself.
So, what happens if you do just
paste(object$components[1], object$components[2],
object$components[3], object$components[4], sep = ",")
Or simpler yet, what happens if you do each of these?
cat(object$components[1],'\n')
cat(object$components[2] ,'\n')
cat(object$components[3] ,'\n')
cat(object$components[4] ,'\n')
And are any of these very different if you use print() instead of
cat(), without the ,'\n', of course.

It has to be related to 'cat' because the output of 'cat' is

why it is truncated. I have been unable to form an array like is in
the test program. Do you think there is something else that is
gobbling up the output from cat that would make it appear to be
truncated?

I certainly wouldn't draw that conclusion. Without a reproducible
example, my assumption would be that it is unrelated to cat().

if that is the case that a reference error is not thrown and just
the output of the cat call is affected.
