Batch mode problem: figure margins too large (code corrected for word wrap)

First of all, I apologize for the triple post, but I did not see that the
word wrap on the r-help list site would render my code unusable. So here it
is again.  Hoping that this time it will work if you cut and paste it in
your Rgui.

I have a program that works well in Rgui but that does not work in a batch
file (Execution halted).

Here's the code (it will work on your R, but you need internet access
through R as it will download a table from a US gov site).

#Code Start
download.file("http://www.cftc.gov/files/dea/history/deacot2005.zip",
"c:/deacot2005.zip", "internal", quiet = FALSE, mode = "wb",cacheOK = TRUE)
unzipped<-zip.file.extract("c:/annual.txt", zipname = "deacot2005.zip")
#Unzip
data <-read.table(unzipped, header=TRUE, sep=',')
windows(height=11,width=8.5)

z <- layout(matrix(c(1:8), 4,2, byrow = TRUE))
for (i in 1:8) {  #loop to fill layout
tbonds<-data[data$'Market.and.Exchange.Names'==
"U.S. TREASURY BONDS - CHICAGO BOARD OF TRADE ",] #choose only T-Bonds
ordered<-tbonds[order(tbonds[,3]),]    #order by date
longb<-ordered[,c(3,9)]
longb[,1]<-as.Date(longb[,1],format="%Y%m%d") #to transform to date format
par(mar=c(2.5, 3.5, 2, 4.5)) #need this par for mtext
plot(longb,type="l",las=1,xlab="",ylab="",bty="l",cex.axis=0.9)
end<-(longb)[nrow(ordered),]  #mtext text
end0<-(longb)[nrow(ordered)-1,]   #mtext text
now<- paste(' Last:',end[,2],"\n",'Prev:',end0[,2])    #mtext text
mtext(now,side=4, las=2,adj=0,padj=0.5,cex=0.5) #mtext text
}
dev.print(pdf, file="c:/CFTC.pdf",height=10,width=8,paper="letter")
#Code end

As you can see, I need a special par(mar) to make room for the margin text
(mtext).

When I run this program through a batch file I get this message :

...
+ longb<-ordered[,c(3,9)]
+ longb[,1]<-as.Date(longb[,1],format="%Y%m%d") #to transform to date format
+ par(mar=c(2.5, 3.5, 2, 4.5)) #need this par for mtext
+ plot(longb,type="l",las=1,xlab="",ylab="",bty="l",cex.axis=0.9)
+ end<-(longb)[nrow(ordered),]  #mtext text
+ end0<-(longb)[nrow(ordered)-1,]   #mtext text
+ now<- paste(' Last:',end[,2],"\n",'Prev:',end0[,2])    #mtext text
+ mtext(now,side=4, las=2,adj=0,padj=0.5,cex=0.5) #mtext text
+ }
Error in plot.new() : figure margins too large
Execution halted

I tried to remove the windows(height=11,width=8.5) as I don't need it in
batch mode, but it prevented the PDF creation as it  " can only print from
screen device".

dev.print(pdf, file="c:/CFTC.pdf",height=10,width=8,paper="letter")
Error in dev.print(pdf, file = "c:/CFTC.pdf", height = 10, width = 8,  : 
	can only print from screen device
Execution halted

Here's what I have in my windows batch file

Set TZ=GMT
PATH C:\Program Files\R\rw2010\bin
Rterm --internet2 --no-restore --no-save <problem.R> result.txt 2>&1

I'm on win2k,

Be nice with me.  I've been a R user for only 2 weeks.
