title problem

 It seems that there is a problem in
 displaying subtitle in general, independently from
 multi-plot display. when I do
 
 plot (c(1,2,3), c(9,8,7), type = "l")
  title(main = "Main title", sub ="Sub title",cex.main=2,
 cex.sub = 2)

 subtitle doesn't get displayed

Try the line= argument on title()

opar <- par(oma = 4 * c(1, 1, 1, 1),

no.readonly =

TRUE)

par(mfrow = 1:2)
plot(1:3, 9:7)
plot(1:3, 7:9)
for(i in 1:3) title(main = i, line = i, outer =

TRUE)

par(opar)

I was not sure what Carol was hoping for. I assumed

she was

hoping for  
the full page analog of what subtitle would do with

an

individual  
plot, i.e. that the subtitle would be below the plots

and

centered. If  
she were hoping for just another line below the main

title,

then your  
strategy or using "\n" within the string would be
effective.

I think that she may need to use mtext() in order to

get a

"true" sub- 
title of the first sort.

Thanks Gary. No I want one subtitle for all

plots

below the main  

title. subtitle should work but if doesn't at

the

worst case I  

could do as follows:

title(main = "Main title\nSub title",outer =

TRUE,

cex.main=1.5,...)

You are right David/Carol. It seems

outer=T

does not work for "Sub title". I'm not

sure

what Carol is looking for, but in case

you

need separate sub

titles for each graph, then you may want

to

use more than

one title statement. Like:


par(oma=c(2,2,2,2))par(mfrow =
c(1,2))plot(c(1,2,3),
c(9,8,7))title(sub ="sub title 1",
cex.sub = 0.75)plot(c(1,2,3),
c(9,8,7))title(sub ="sub title 2",
cex.sub = 0.75)

title(main = "Main title",
cex.main=1.5, outer = TRUE)
Not sure about how to do it for a single
"sub title" for whole graph.
Anyone?~Gary

Hi Carol,



Try this




par(oma=c(2,2,2,2))

par(mfrow = c(1,2))

plot(c(1,2,3), c(9,8,7))

plot(c(1,2,3), c(9,8,7))

title(main = "Main title", sub ="Sub
title",outer = TRUE, cex.main=1.5,


cex.sub = 1.5)




I'm curious about what you are seeing

with

that

sequence. On a Mac running R 2.10.0 I am

not

seeing the

subtitle.

par(oma=c(2,2,2,2)) -- can be used to

define

outline of the

plot. Arguments

here are for "bottom", "left",
"top", "right"; which ofcourse can be
changed

according to need. HTH

Hi,

I got problem in using title function to

create a title for

multiple plots

presented together by par. As can be seen

in

the attached

file, the title is

displayed truncated and the subtitle

doesn't

get

displayed. Here is the

code:



par(mfrow = c(1,2))

plot(c(1,2,3), c(9,8,7))

plot(c(1,2,3), c(9,8,7))

title(main = "Main title", sub ="Sub
title",outer = TRUE, cex.main=1.5,

cex.sub = 1.5)
