Subject: [Rd] Matplot does not work with x being POSIXt class (PR#9412)
Message-ID: <20061207125601.00D2257349@slim.kubism.ku.dk>

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")
## [1] "POSIXt"  "POSIXlt"
matplot(x, y)
Error in matplot(x, y) : 'x' and 'y' must have only 1 or the same number
of columns

Additionally, matplot with x being Date class does not use apropriate
annotation for x axis.

Thank you!

Gregor
