When I do this (highly simplified example):
plot(as.POSIXct(c("1984-01-01","1984-01-02")), c(1,2), col=2)
I get a partially red (col=2) x-axis between and including the first and last tick marks. Otherwise ok. Only happens with POSIXct or POSIXlt dates.
This one has already been fixed in r-patched and r-devel (to be R-1.8.0).
Also, POSIX dates cannot be used on the y-axis? POSIXlt gives an error, and POSIXct is unformatted.
[That's a question for r-help, not appropriate for a bug report.]
?plot.POSIXct points you to a function axis.POSIXct() to be used as in:
plot(c(1,2), as.POSIXct(c("1984-01-01","1984-01-02")), yaxt="n")
axis.POSIXct(2, as.POSIXct(c("1984-01-01","1984-01-02")))Uwe Ligges
