I have a character "2006-11-06" which was originally scanned from a
csv file. This character is
named date. I now use mtext (date) on a plot and i see strange cluttered
characters instead of
2006-11-06. I tried many ways but i dont know whats going on. Then for testing i
made an
artificial character d <- ("2006-11-06") and now when i do mtext
(d) it shows up on the plot.
While both date and d return "2006-11-06" only d shows up on the
plots. Any help would be appreciated.

I now use mtext (date) on a plot and i see strange cluttered characters instead ofThen it is not a character but some date/time object such as a POSIXlt class. mtext() does not have an appropriate method for it. If this date is x, just plot as.character(x) instead. Uwe Ligges> 2006-11-06. I tried many ways but i dont know whats going on.

When you just print the object, the print method works out that it is a date object and silently converts it to a character string to be printed. Try this: mtext(format(date,"%Y-%m-%d"),...) Also note that it isn't a great idea to use "date" to name a variable. Even though you can now get away with it, using the same name for two things (a function and a variable) often comes back to haunt one. Jim
