If you want to leave the last plot(s) in a such a figure blank,
and continue on with another figure, how does that work?

For example:

par(mfrow=c(2,3)) #set up 2 rows x 3 columns
plot(1:10, main="Plot 1")
plot(1:20, main="Plot 2")
plot(1:30, main="Plot 3")
par(mfg=c(2,2))  # start next plot at 2,2 instead of 2,1
plot(1:40, main="Plot 4")

# What if 5th plot is to start on next page?
# Why do plots 5 and 6 overlay plots 1 and 2 instead
# of being on a new page?
par(mfg=c(1,1))
plot(1:50, main="Plot 5")
plot(1:60, main="Plot 6")

If "par(mfg=c(1,1))" is left out, Plot 6 is on the next figure.

The "new=T" parameters seems like a possible solution, but gives this
warning and is ignored:
     Warning messages:
     1: parameter "new" couldn't be set in high-level plot() function

par(mfrow=c(2,3)) #set up 2 rows x 3 columns
plot(1:10, main="Plot 1", new=T)
plot(1:20, main="Plot 2")
plot(1:30, main="Plot 3")
par(mfg=c(2,2))  # start next plot at 2,2 instead of 2,1
plot(1:40, main="Plot 4")

# What if 5th plot is to start on next page?
# Why do plots 5 and 6 overlay plots 1 and 2 instead
# of being on a new page?
par(mfg=c(1,1))
plot(1:50, main="Plot 5", new=T)
plot(1:60, main="Plot 6")

How do I create a series of plots in one figure and control
when a new figure is created? (without using dummy blank placeholder plots)

The example above is only for discussion.  I really want to do this in a
loop
and create 5 plots per figure, and repeat this for many pages in a PDF file.


Does this do what you want?

layout(rbind(c(1, 2, 3),
             c(0, 4, 0)))
plot(1:10, main="Plot 1")
plot(1:20, main="Plot 2")
plot(1:30, main="Plot 3")
plot(1:40, main="Plot 4")
# new page!
plot(1:40, main="Plot 5")
