Bert,
What you are saying - is a problem with people who are using Excel. It is not
Excel's problem that people are sending data in an unstructured way. I agree -
Excel may not be the right tool when you are doing some complicated data
analysis (like for e.g. statistical modeling) - but that

Thank you for the replies, Uwe and Marc. These are explanations that make
perfect sense. However, shouldn't the behavior of plot.factor include the
option of type = n for consistency with the default plot function?

y = c(2, 7, 9, 10, 11)

Output will be: 7, 9.
Hope it helped. :)

Dear R-Gurus
I have a data frame (from CSV file) which has its first column called Date.
The Date is in the format mm/dd/. I was trying to get the weekday for
these dates and I tried using wday() and day.of.week() functions and both
of them gave me precisely the wrong answers. I think the
Yes dput() for a reproducible example with some minimal
reproducible code (and the packages day.of.week and wday() come

precisely the wrong answers -- interesting turn of phrase.
