Network Blitz I'm trying to generate a graph to summarize Interest Rate Parity. This involves a scatterplot of x against y where the x and y limits are set so to center the graph on 0,0 and then adding each axis line and a 45 degree line. Using CAR's scatterplot (sample code below) everything except the axes plot fine: scatterplot( Interest.Rate.Dif ~ ForPrm| profit, xlim=c(-1,1),ylim=c(-1,1)) abline(0,1) abline(v=0) abline(h=0). The problem is that the vertical (horz) line lies aprox 3% below (to the left) of the 'zero' tick (or perhaps the zero tick lies above the zero point). My intution is that there are multiple coordnet systems, but who knows.... Any insights, suggestions etc, are welcome, cheers, Joel Kincaid, Asst.

(CAR) Scatterplot and problems (?) with abline
2 messages · Joel Kincaid, John Fox
Dear Joel, To draw marginal boxplots around the scatterplot, the scatterplot function in car sets some plotting parameters, then resets these to their previous value when the function exits, making it impossible to add to the plot. This behaviour is intentional, but I agree that it can be problematic. An immediate fix is to comment out the command on.exit(par(mar = mar, mfcol = mfcol)) in scatterplot.default. If you do this, be aware that these plotting parameters will be changed for the current graphics device. A more permanent solution is to add an argument such as reset.par (defaulting to FALSE) to the function, which I'll do in the next version of car. Thanks for bringing the problem to my attention, John
