A very nice vignette indeed!  Didn't know about these.
Thank you, Sarah, and thanks to the author, Baptiste Auguie !

Hi,

You're mixing base plot and ggplot2 grid graphics, which as you've
discovered doesn't work.

Here's av strategy that does:

This vignette has a good overview, well as info specific to that package.

Re: [R] par(mfrow=c(3,4)) problem

[PIKAL Petr]

Hi

You combine basic graphic (par) and grid graphic (ggplot), which is possible 
but not strightforward.
You could check it e.g.
par(mfrow=c(1,2))
plot(1,1)
plot(1,2)
library(ggplot2)
d <- ggplot(diamonds, aes(carat, price))
d + geom_point(alpha = 1/10)
d + geom_point(alpha = 1/20)

In grid graphic you could use ?facet_grid to get multiple plots on one page.

Or you could use Google and find

www.cookbook-r.com/Graphs/Multiple_graphs_on_one_page_(ggplot2)/
http://www.sthda.com/english/articles/24-ggpubr-publication-ready-plots/81-ggplot2-easy-way-to-mix-multiple-graphs-on-the-same-page/

I'm not sure if it's on CRAN but you can devtools::github_install it.

[R] par(mfrow=c(3,4)) problem

[greg holly]

Hi all;

I need to put 12 different plot2 into the same matrix. So my array for the
matrix will be par(mfrow=c(3,4)).  I am running ggplot2 to produce my 12
plots. For some reason, par(mfrow=c(3,4)) did not turn out 3*4 matrix.

my basic R codes for each plot is
par(mfrow=c(3,4))
library(ggplot2)
p <- ggplot(a, aes(x=Genotypes, y=Plant_hight, size=Plant_hight,
color=Showing_rate)) +
.
.

Best regards,

Greg

Re: [R] par(mfrow) for heatmap plots

[Jeff Newmiller]

The answer is "don't do that" because that function abuses par. Use lattice or 
ggplot2 with grid graphics to plot multiple heatmaps.

I'm currently using the R base version for Mac Os, 3.0.3 .

But that's correct, if you don't plot something afterwards. Try plotting 8 x-y 
graphs, then you'll see that 8 small plot will appear (unless the margins will 
prove to be too large).

Re: [R] par(mfrow=c(1,3)) and postscript(file=)

[Sarah Goslee]

Probably you need to put the par() function after the postscript() function
- the par changes apply only to the current device, and there's no
postscript device until you start it.

But since you haven't provided an example, it's impossible to be certain.

[R] par(mfrow) or split.screen with climatol roseavent plot?

[Jan Näs]

Hi
I trying to add a wind rose as a plot together with other plots.
Im unsing the roseavent function from the climatol package.

Ive tried par(mfrow=c(2,2))
but when plotting the windrose:
rosavent(windfreq_rose,4,3,ang=-3*pi/16,main=Windrose) it skips one
position, and when plotting the next one it blanks everything else.

Ive also tried split.screen, but the roseavent only blanks everything
else as it is plotted.

Does anyone have an idea how I can add my windrose without haveing to
cut and paste it in gimp afterwards?

Kind regards
Jan

Many specialized plotting routines will override the par settings.   
Notice that in the rosavent code you find:


 par(mar = margen, new = FALSE)

You may need to do a bit of code hacking to get your desired 2 x 2  
arrangement.

[R] par mfrow in function problem

[casperyc]

Hi all,

I defined the following

#
myhist=function(x){
hist(x,xlab=,main=)
h=hist(x)
xfit=seq(min(x),max(x),length=100)
yfit=dnorm(xfit,mean(x),sd=sd(x))
yfit=yfit*diff(h$mids[1:2])*length(x)
lines(xfit, yfit, col=blue, lwd=2)
}
#

individually, it worked fine

however, if I used

par(mfrow=c(2,2))

each time i run myhist

it produces TWO plots,

one without the 'lines',
and one with the 'lines'

why is that??

Thanks.

Re: [R] par mfrow in function problem

[Joshua Wiley]

Dear Casper,

This is because you create two histograms, the first with the direct
call to hist(), the second at: h = hist(x).  That is also why even
though you set the xlab and main to be blank in your first one,the
histogram with the normal line added actually was titled.  Normally,
hist() just overwrites the plot in the current device, but since there
are 4 slots in the device (par(mfrow = c(2, 2))), you then saw
multiple histograms.  You can avoid this by setting the plot = FALSE
argument in the histogram you do not want plotted.  Here is how I
would revise it:

par(mfrow=c(2,2))
#
myhist=function(x){
   hist(x,xlab=,main=)
   h=hist(x, plot = FALSE)
   xfit=seq(min(x),max(x),length=100)
   yfit=dnorm(xfit,mean(x),sd=sd(x))
   yfit=yfit*diff(h$mids[1:2])*length(x)
   lines(xfit, yfit, col=blue, lwd=2)
}
#

## an example
myhist(rnorm(400))


HTH,

Josh

Re: [R] 'par mfrow' and not filling horizontally

[Ivan Calandra]

  Hi!

I think you've got already all useful solutions, but I usually just 
change mfrow to c(2,2).
There is then free space left, but I usually edit my graphs in 
Illustrator anyway.

 Greetings, Folks.
 I'd appreciate being shown the way out of this one!
 I've been round the documentation in ever-drecreasing

plot(X0,Y0,pch=+,col=blue,xlim=c(-3,3),ylim=c(-3,3),
xlab=X,ylab=Y,main=My Plot,asp=1)

 As you will see, both plots have been extended laterally
 to fill the plotting area horizontally, hence extend from
 approx X = -8 to approx X = +8 (on my X11 display), despite
 the xlim=c(-3,3); however, the ylim=c(-3,3) has been
 respected, as has asp=1.

 What I would like to see, independently of the shape of
 the graphics window, is a pair of square plots, each with
 X and Y ranging from -3 to 3, even if this leaves empty
 space in the graphics window on either side.

 Hints?

 With thanks,
 Ted.

[R] 'par mfrow' and not filling horizontally

[Ted Harding]

Greetings, Folks.
I'd appreciate being shown the way out of this one!
I've been round the documentation in ever-drecreasing
circles, and along other paths, without stumbling on
the answer.

The background to the question can be exemplified by
the example (no graphics window open to start with):

  set.seed(54321)
  X0 - rnorm(50) ; Y0 - rnorm(50)

  par(mfrow=c(2,1),mfg=c(1,1),cex=0.5)
  plot(X0,Y0,pch=+,col=blue,xlim=c(-3,3),ylim=c(-3,3),
  xlab=X,ylab=Y,main=My Plot,asp=1)

  par(mfg=c(2,1))
  plot(X0,Y0,pch=+,col=blue,xlim=c(-3,3),ylim=c(-3,3),
  xlab=X,ylab=Y,main=My Plot,asp=1)

As you will see, both plots have been extended laterally
to fill the plotting area horizontally, hence extend from
approx X = -8 to approx X = +8 (on my X11 display), despite
the xlim=c(-3,3); however, the ylim=c(-3,3) has been

Ted, 

Try this:

 set.seed(54321)
 X0 - rnorm(50) ; Y0 - rnorm(50)

 # add pty = s
 par(mfrow=c(2, 1), mfg = c(1, 1), cex = 0.5,
 pty = s)  

 plot(X0, Y0, pch = +, col = blue,
  xlim = c(-3, 3), ylim = c(-3, 3),
  xlab = X, ylab = Y, main = My Plot,
  asp = 1)

 par(mfg = c(2, 1))
 plot(X0, Y0, pch = +, col = blue, 
  xlim= c(-3, 3), ylim = c(-3, 3),
  xlab = X, ylab = Y, main = My Plot,
  asp = 1)


See ?par and 'pty', which defaults to m.

Thanks Greg, William, Marc  Bert for the suggestions. It seems
that Bert's suggestion of 'layout' may work best for my real example
(the one I posted was a simple one). It is also necessary to add
par(pty=s).

Greg: I must study squishplot() -- it looks useful.

William, Marc: I had tried pty=s in my real example (I inadvertently
omitted it from the dummy example I posted), but it still did not
work -- see Case B of the real example below.

Anyway, here is an instance of the real problem. DISCLAIMER: This
is being done as an exploration of concept and does not necessarily
represent my true state of mind ...

## Code common to all approaches (Alterbative continuations A and B):
library(MASS)
M - 10 ; N - 2  ; plur - 's
set.seed(54321)
mu - (-3)+6*(0:(M-1))/(M-1)
mu - rep(mu, N)   ## M evenly spaced on (-3,3)
Y - matrix(rnorm(M*N,mean=mu),ncol=N) ## N Y's for each mu
KDE - kde2d(x=mu, y=Y, h=2.5,  n=100, lims=c(-5,5,-5,5,-5.0,5.0))
S.x - KDE$x ; S.y - KDE$y ; S.z - KDE$z
## For each value of Y in the KDE grid, find the mu with max KDE:
Mxs - numeric(100)
for(j in (1:100)){ Mxs[j] - S.x[which(S.z[,j]==max(S.z[,j]))] }

## A: Using Bert's 'layout' approach with pty=s as well:
layout(matrix(1:2, nrow=2),wid=1,height=c(1,1), resp=TRUE)
par(cex=0.5,pty=s)

plot(mu,Y,pch=+,col=blue,asp=1,xlim=c(-5,5),ylim=c(-5,5),
 xlab=True mu, ylab=Sampled Y's,
 main=paste(KDE for (mu,Y),
 M, mu's, ,N, Y,plur, per mu,sep=))
contour(S.x, S.y, S.z, nlevels=7, drawlabels=FALSE, add=TRUE)
lines(S.x,S.y,col=green)
for(j in (1:100)){ Mxs[j] - S.x[which(S.z[,j]==max(S.z[,j]))] }
lines(Mxs,S.x,col=red)

plot(S.x[1:100],Mxs[1:100],asp=1,pch=+,col=red,
xlim=c(-5,5),ylim=c(-5,5),
xlab=Future Observed Y,ylab=MLE of mu by KDE,
main=MLE of mu by KDE for this Sim vs Future Y)
lines(c(-3,3),c(-3,3),col=green)
lines(c(-3,-3),c(-3,3)) ; lines(c( 3, 3),c(-3,3))
text(0,3.5,-- Range of True mu used --)

##C: Using par(pty=s) with par(mfrow) leaving out 'layout':
plot.new()
par(mfrow=c(2,1),mfg=c(1,1),cex=0.5,pty=s)
plot(mu,Y,pch=+,col=blue,asp=1,xlim=c(-5,5),ylim=c(-5,5),
 xlab=True mu, ylab=Sampled Y's,pty=s,
 main=paste(KDE for (mu,Y),
 M, mu's, ,N, Y,plur, per mu,sep=))
contour(S.x, S.y, S.z, nlevels=7, drawlabels=FALSE, add=TRUE)
lines(S.x,S.y,col=green)
for(j in (1:100)){ Mxs[j] - S.x[which(S.z[,j]==max(S.z[,j]))] }
lines(Mxs,S.x,col=red)

par(mfg=c(2,1))
plot(S.x[1:100],Mxs[1:100],asp=1,pch=+,col=red,
xlim=c(-5,5),ylim=c(-5,5),
xlab=Future Observed Y,ylab=MLE of mu by KDE,
main=MLE of mu by KDE for this Sim vs Future Y)
lines(c(-3,3),c(-3,3),col=green)
lines(c(-3,-3),c(-3,3)) ; lines(c( 3, 3),c(-3,3))
text(0,3.5,-- Range of True mu used --)
#

Anyway, thanks! It has helped.
Ted.

remove your asp=1 and try again to see if that is what you want.

[R] par(mfrow = ) resets par('cex'), not reduces it

[[EMAIL PROTECTED]]

Hello group!

I use R 2.8.0 . I've just found out that par(mfrow =) *resets* par
('cex'), not reduces it as documented. To reproduce:

par(cex = 0.5)
par(mfrow = c(2, 2))
print(par('cex'))

It outputs 0.83, not 0.415 as expected.

Particularly such a behavior makes plot.acf effectively ignore par
('cex') value for multivariate case. I guess there are more situations
where the documented behavior would be more appropriate.

I think it is bug in par implementation not in documentation. Could
anyone comment on this?

 Hi All,

 I'm going to draw 8 plots in one page. I want the plots to be arranged
 in two rows, each row has 4 plots. So, I set the it par(mfrow=c(2,4)).

 However, there might be too many plots in a page, all the 8 plots were
 drawn in triangular shape, which makes the x-y coordinate scale not in
 same length, the x-axis length is much shorter than the y-axis length.

 Could anybody let me know how to make the x-y coordinate length be the
 same, like the square box?


 Thanks in advance.

[R] par(mfrow=c(4,2)) vs. lattice

[stephen sefick]

I have had good sucess with the par(mfrow=c(#,#)) for formating graphs and
they look good to me.  I have seen a lot of use of the lattice package and
thought I would go fishing on the list for y'all's comments.  Is there a
time when lattice would be easier more appropriate for certain graphics over
par(mfrow(#,#)).
Just wondering

Re: [R] par(mfrow=c(4,2)) vs. lattice

[Bert Gunter]

FWIW:

I use lattice exclusively. One difference from the mfrow approach is that
lattice automatically provides (if desired) the same scaling on all plots,
necessary to make visual comparisons. It also provides an easy way to
appropriately label and and arrange the plots, as well as to provide
standard enhancements (e.g. a benchmark curve or line on all graphs) on all.
Again, this makes visual comparison among the plots possible, which is what
I mostly have to do. Customizable panel functions give me all the
flexibility and control I need. Generally, it's not hard to write your own,
using the extensive building blocks Deepayan has provided.

All of this is possible through mfrow of course --- you just have to do it
manually. Lattice makes it easy (for me!).

Note: there **is** a considerable learning curve, but Deepayan has done an
exemplary job of documenting lattice, and his new book is a well-written and
extensive resource for self-learning (all IMHO, of course).

Just my $.02.

Subject: [R] par(mfrow=c(4,2)) vs. lattice

I have had good sucess with the par(mfrow=c(#,#)) for formating graphs and
they look good to me.  I have seen a lot of use of the lattice package and
thought I would go fishing on the list for y'all's comments.  Is there a
time when lattice would be easier more appropriate for certain graphics over
par(mfrow(#,#)).
Just wondering

Re: [R] par(mfrow=c(4,2)) vs. lattice

[Gabor Grothendieck]

mfrow is for classic graphics and when the graphs are unrelated.

lattice is for grid graphics and typically when the panels are related
such as being the same plot but conditioned on different factor levels.

These are typical uses only as one can write arbitary panels with lattice
and produce related graphs using mfrow with some extra work.
