plot legends without border and with white background

Question

I have a legend in a plot with a line  from an abline-statement  going through it  How can I achieve that the abline gets invisible in proximity of the legend  This should be achievable by setting the legend background white  without borders  but how can I achieve this  Assume the graph should look like this   windows options width 30  height 12  plot 1 10  abline v seq 1 10 1   col  grey   lty  dotted   legend 4 8  3   This legend text should not be disturbed by the dotted grey lines     And to get it a bit more complicated  If the legend interferes with the dots of the dot-plot  How can I achieve that the ablines gets invisible in proximity of the legend  as above   but that the dots are still visible   windows options width 30  height 12  plot 1 10  abline v seq 1 10 1   col  grey   lty  dotted   legend 1  5   This legend text should not be disturbed by the dotted grey lines  but the plotted dots should still be visible     And finally  Is there a way to introduce line-breaks in legend statements

Use option bty    n  in legend to remove the box around the legend  For example   legend 1  5          This legend text should not be disturbed by the dotted grey lines  nbut the plotted dots should still be visible          bty    n

As documented in  legend you do this like so   plot 1 10 type    n   abline v seq 1 10 1   col  grey   lty  dotted   legend 1  5   This legend text should not be disturbed by the dotted grey lines  nbut the plotted dots should still be visible  box lwd   0 box col    white  bg    white   points 1 10 1 10      Line breaks are achieved with the new line character  n  Making the points still visible is done simply by changing the order of plotting  Remember that plotting in R is like drawing on a piece of paper  each thing you plot will be placed on top of whatever s currently there   Note that the legend text is cut off because I made the plot dimensions smaller  windows options does not exist on all R platforms
