Including >type="l"< or >type="b"< in plot command causes problems with grid: ..... layout <- par(fin=c(3.46,3.46),mai=c(0.63,0.63,0.05,0.05),mgp=c(2,0.7,0), tcl=0.35,las=1,cex.axis=0.9,cex.lab=1,ps=10) plot(data.trout[,1],data.trout[,2],xlim=range(6.5,8.5),ylim=range(120,470), xlab="pH",ylab=expression(paste("P"[O[2]], " (Torr)")),bg="white",grid(lty=2,lwd=0.6)) ..... This plot works fine. Note: the grid is "in the back", i.e. does not overlay tick marks, plot symbols or boundary lines. Including type="b" (or "l") causes an error message: ... Error in plot.window(xlim, ylim, log, asp, ...) : "log=" specification must be character ... Including >log=""< within the plot command gets rid of the message. However, now the grid (light grey) overlays tick marks, lines of the plot, and boundary lines.
