I am often taking the absolute value of a difftime object (after
coercing it to numeric) in order to see how far apart in time
two events are. For example, I might want to know if two events
occurred within 100 days of each other using something like
abs(difftime(Date1, Date2)) < 100
Below is a s

As Peter said, matplot plots matrices. The columns of a matrix are
vectors of numbers. A POSIXlt object is not a vector of numbers, it
is a list. So it shouldn't work. And should not be expected to work.
But with a POSIXct object it will work.
x <- strptime(as.character(x), format="%Y-%m-%d")

Hi,
Matplot works with x being Date class but not POSIXt. Here is the
example with R version 2.5.0 Under development (unstable) (2006-12-06
r40129)
Example:
x <- Sys.Date() - c(1:10)
y <- cbind(1:10, 10:1)
class(x)
## [1] "Date"
matplot(x, y)
x <- strptime(as.character(x), format="%Y-%m-%d")

That it does not run does not mean there is a bug in R, so why do you
submit a bug report that must be handled manually by some R Core member?
Please tell us the error message, we cannot help you unless you provide
us with the relevant details.
