Dear colleagues, I wish to create a figure with 6 plots arranged vertically with no spacing between them as they all have a common x-axis. However, using the code below I'm unable to get the plot area the same size for each plot. The bottom plot with the x-axis label is smaller than the others, as is the top plot which has larger margins. How can I get the plot region the same size for all 6 plots, whislt still having a large enough margin for the x-axis label on the bottom plot? y<-rnorm(1:100) x<-rnorm(1:100) par(mfrow=c(6,1)) par(mar=c(0,5,2,5)) plot(y~x, xlab="", xaxt="n", ylab="y") par(mar=c(0,5,0,5)) plot(y~x, xlab="", xaxt="n", ylab="y") plot(y~x, xlab="", xaxt="n", ylab="y") plot(y~x, xlab="", xaxt="n", ylab="y") plot(y~x, xlab="", xaxt="n", ylab="y") par(mar=c(4,5,0,5)) plot(y~x, xlab="x", ylab="y") Regards Richard -- View this message in context: http://r.789695.n4.nabble.com/Plot-Area-Dimensions-tp4650051.html Sent from the R help mailing list archive at Nabble.com.
I think this task would be easier in lattice
library(lattice)
xyplot(y + y + y + y + y + y ~ x, outer=TRUE, layout=c(1,6),
strip=FALSE, strip.left=TRUE,
ylab="6 copies of the Y variable",
main="put an interesting title here")
Six different y variables instead of six copies of the same would give a
more
interesting plot:
tmp <- data.frame(matrix(rnorm(700), 100, 7,
dimnames=list(1:100,
c("x","y1","y2","y3","y4","y5","y6"))))
xyplot(y1 + y2 + y3 + y4 + y5 + y6 ~ x, data=tmp,
outer=TRUE, layout=c(1,6),
strip=FALSE, strip.left=TRUE,
ylab="6 levels of the y response",
main="put an interesting title here")

You can also use layout() with base graphics. This example sets up a column of 14 strips and allocates 3 strips to the top and bottom graphs and 2 strips To the four middle graphs. Using Richard's tmp dataframe: layout(matrix(c(1, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 6), 14, 1)) layout.show(6) par(mar=c(0,5,2,5)) plot(y1~x, tmp, xlab="", xaxt="n", ylab="y") par(mar=c(0,5,0,5)) plot(y2~x, tmp, xlab="", xaxt="n", ylab="y") plot(y3~x, tmp, xlab="", xaxt="n", ylab="y") plot(y4~x, tmp, xlab="", xaxt="n", ylab="y") plot(y5~x, tmp, xlab="", xaxt="n", ylab="y") par(mar=c(4,5,0,5)) plot(y6~x, tmp, xlab="x", ylab="y") --------------------------------------------- David L Carlson Associate Professor of Anthropology Texas A&M University College Station, TX 77843-4352> -----Original Message----- > From: r-help-bounces at r-project.org [mailto:r-help-bounces at r- > project.org] On Behalf Of Richard M.

The key is to not change the margins, set them once and stick with those margins. The next question then becomes "how do I leave area at the top/bottom for the title and common axis?" to which the answer is "Set outer margins at the beginning". Modifying your code: y<-rnorm(1:100) x<-rnorm(1:100) par(mfrow=c(6,1), mar=c(0,5,0,5), oma=c(4,0,2,0)) plot(y~x, xlab="", xaxt="n", ylab="y") plot(y~x, xlab="", xaxt="n", ylab="y") plot(y~x, xlab="", xaxt="n", ylab="y") plot(y~x, xlab="", xaxt="n", ylab="y") plot(y~x, xlab="", xaxt="n", ylab="y") plot(y~x, xlab="x", ylab="y") On Mon, Nov 19, 2012 at 8:51 AM, Richard James <Richard.J.Cooper@uea.ac.uk>wrote:> Dear colleagues, > > I wish to create a figure with 6 plots arranged vertically with no spacing > between them as they all have a common x-axis. > > However, using the code below I'm unable to get the plot area the same size > for each plot. > > The bottom plot with the x-axis label is smaller than the others, as is the > top plot which has larger margins. > > How can I get the plot region the same size for all 6 plots, whislt still > having a large enough margin for the x-axis label on the bottom plot? > > y<-rnorm(1:100) > x<-rnorm(1:100) > par(mfrow=c(6,1)) > par(mar=c(0,5,2,5)) > plot(y~x, xlab="", xaxt="n", ylab="y") > par(mar=c(0,5,0,5)) > plot(y~x, xlab="", xaxt="n", ylab="y") > plot(y~x, xlab="", xaxt="n", ylab="y") > plot(y~x, xlab="", xaxt="n", ylab="y") > plot(y~x, xlab="", xaxt="n", ylab="y") > par(mar=c(4,5,0,5)) > plot(y~x, xlab="x", ylab="y") > > Regards > > Richard > > > > -- > View this message in context: > http://r.789695.n4.nabble.com/Plot-Area-Dimensions-tp4650051.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >-- Gregory (Greg) L.
