editing a correlogram

Hi,

In this case the spdep::plot.spcor() function, which I think you are using, doesn't provide the mechanism for the caller to override the default pch value.  You can see this by looking at the pl.spcor function (as shown way below.)  I think it may be easiest for you to simply rewrite the function with the plotting parameters assigned as arguments.

Cheers,
Ben

spdep::plot.spcor

function (x, main, ylab, ylim, ...) 
{
    if (missing(main)) 
        main <- x$var
    if ((x$method == "I") || (x$method == "C")) {
        lags <- as.integer(rownames(x$res))
        to.plot <- which((x$res[, 3] > 0) & (x$res[, 3] != Inf))
        sd2 <- rep(0, nrow(x$res))
        sd2[to.plot] <- 2 * sqrt(x$res[to.plot, 3])
        if (missing(ylim)) {
            ylim <- range(c(x$res[, 1] + sd2, x$res[, 1] - sd2))
        }
        if (missing(ylab)) 
            if (x$method == "I") 
                ylab <- "Moran's  I"
        if (x$method == "C") 
            ylab <- "Geary's  C"
        plot(lags, x$res[, 1], type = "p", pch = 18, ylim = ylim, 
            main = main, ylab = ylab, xaxt = "n")
        arrows(lags, x$res[, 1] + sd2, lags, x$res[, 1] - sd2, 
            length = 0.1, angle = 90)
        arrows(lags, x$res[, 1] - sd2, lags, x$res[, 1] + sd2, 
            length = 0.1, angle = 90)
        axis(1, at = lags)
        abline(h = x$res[1, 2])
    }
    else {
        res <- as.vector(x$res)
        lags <- as.integer(names(x$res))
        if (missing(ylim)) 
            ylim <- c(-1, 1)
        if (missing(ylab)) 
            ylab <- "Spatial autocorrelation"
        plot(lags, res, type = "h", ylim = ylim, main = main, 
            ylab = ylab, lwd = 4, xaxt = "n")
        axis(1, at = lags)
        abline(h = 0)
    }
}

I tried the function par() and arguments inside the plot(), but some
parameters doesn't change.
For example, the argument pch=, which changes the symbols that represents
the points in the plot doesn't work.

Of course.

The ... argument to the plot method means that you can use standard
base graphics options to customize as you wish.

?par gives the whole list, although they may not all be useful for
correlograms.

If you have specific questions after you try customizing to your
liking, the list can certainly help with details.

Hello,

I've been tried to use the function "sp.correlogram". After plot the
correlogram, I would like to edit the grafic's appearence, to publish it.
It is possible?

Thanks
