Is there a reason that the bottom axis changes color when POSIX data is used in plot function? For example: > timedata <- c("2/3/2003","3/4/2003","5/4/2003") > timedata2 <- strptime(timedata,format="%m/%d/%Y") > numdata <- c(2,3,4) > plot(as.POSIXct(timedata2),numdata,col="red",type="o") As compared to: >

Here's the current definition: plot.POSIXct <- function (x, y, xlab = "", xaxt = par("xaxt"), ...) { axisInt <- function(x, main, sub, xlab, ylab, ...) axis.POSIXct(1, x, ...) plot.default(x, y, xaxt = "n", xlab = xlab, ...) if (xaxt != "n") axisInt(x, ...) } The "col" argument is being passed to axisInt, but it should have been intercepted. Here...

Hi List, I have a problem plotting data using the lineplot.CI command in the sciplot package. I want to plot the data of 2 experimental cases using different lines (traces). Time is on the X-axis. The tricky thing is that the data collection in the second case started later than for the first case. This is to say: the first n data points for the second case are missing. So far so good. However,

Dear R-devels, I'd like to create a plot method for a class of objects that passes the '...' argument to both plot() and legend(), e.g., x <- list(data = rnorm(1000)) class(x) <- "foo" plot.foo <- function(x, legend = FALSE, cx = "topright", cy = NULL, ...){ dx <- sort(x$data) plot(dx, dnorm(dx), type = "l", ...) if (legend)
