[Rd] par(lab= *) / axis(*) bug (PR#791)

[maechler@stat.math.ethz.ch]

As the subject says,
here is example code (with comments) showing the problem:

p1 <- function(lab = c(8,12,7))
{
    ## This `fails' (on a virgin device)
    clab <- paste(lab,collapse=",")
    plot(1,1, xlim = c(0,15), ylim = c(-.8,1), type ="n", axes = FALSE,
         main=paste("plot(*,axes=F); par(lab= c(",clab,"));  axis(*) x 2",sep=""))
    box(col="gray80")
    op <- par(lab = lab) ; on.exit(par(op))
    axis(1, pos = 0)
    axis(2, pos = 0, las = 1)
    par(op)
    op
}

p2 <- function(lab = c(8,12,7))
{
    ## This works  [par()  *BEFORE*  plot() ]
    clab <- paste(lab,collapse=",")
    op <- par(lab = lab) ; on.exit(par(op))

    plot(1,1, xlim = c(0,15), ylim = c(-.8,1), type ="n", axes = FALSE,
         main=paste("par(lab= c(",clab,")); plot(*,axes=F); axis(*) x 2",sep=""))
    box(col="gray80")
    axis(1, pos = 0)
    axis(2, pos = 0, las = 1)
    op ## lab 5 5 7
}

dev.off()
par(mfrow=c(2,1), mar=c(2,2,3,1))
p1()
p2()
