I get the following error message followed by instability in R after the
error message:
Error: Cannot pop the top-level viewport (grid and graphics output
mixed?)
Have reduced something much more complex in my code to a simple test case.
I run the following and then resize the window:
X = seq (1,10)
Y = X^2
opar <- par(no.readonly=TRUE, mar = c(2.5, 3.1, 1, 2))
grid.newpage()
pushViewport (viewport(x=0,y=0,width=1,height=1,just=c(0,0), name='base'))
pushViewport (viewport(x=0,y=0.5,width=1,height=0.5,just=c(0,0)))
par (fig=gridFIG())
# plot in top half of page
plot (X,Y,col='black',xlab="",main='',cex.axis=.7)
# get toplevel view
seekViewport('base')
# create lower viewport
pushViewport(viewport(x=0,y=0,width=1, height=0.5, just=c(0,0)))
par(new=TRUE,fig=gridFIG())
plot (X,Y,col='grey')
Upon resize will display the above error. R will then become unstable
and I have to terminate. This is in the windows version of R 2.8.0.
Am I doing something wrong? I am using viewports as I am doing something
more complex than the above in code with a number of additional viewports
(In this case I could use
layout or split.screen)
