Advantages: youget complete control over your layout. Disadvantages: just
abouteverythingelse. Yourgureisnolongerreproducible. Thiscanbecome
increasingly annoying as analyses inevitably get re-run. It can also be time-
consumingto perfectly line upyour panels. I try andavoidthis at allcosts,
butoccasionally it’s youronlyorbest choice.
grid graphics, lattice, ggplot2 Packages like ggplot2 and lattice are great.
Where I think they excelis in exploratory dataanalysis. You might be able
to generate tenggplot gures in the time it would take you to do the same

outswhereeachpanelis thesamesize.

combinepanels.

havetobe simpleratiosofeachother.
2 Where I make a silly analogy to explain the in-
creasing levels of complexity
par(mfrow), layout(), and split.screen() are all capable of basic equal-sized-
panel grid layouts. If you think of creating asmallmultiple layout in Rto be like
putting screws into a wall: par(mfrow) would be the equivalent of grabbing your
Leatherman tohangonepicture frame |it’s allyouneedandit’s fast. layout()
wouldbetheequivalentofhuntingaroundforaproperscrewdrivertohangabunch
ofpictureframes. split.screen wouldbetheequivalentofndingandpluggingin

Don’t graba toolthat’s morecomplexthanit needstobe,butdon’ttry andbuild

3 Questions to ask yourself when making a multi-
panel plot
1. WhatcomparisondoIwanttoemphasize?
2. HowcanIuseordertoenhancethe comparison?
3. Is this a series of plots or does the grid layout matter? (facet_wrap vs.
facet_grid inggplot2terminology)
4. What’s areasonablenumber ofpanelstoshow? Everything? Asample?
5. WhichaxescanIx andwhichneedto vary? Would alogtransformationbe
appropriateandallowtheaxestobecombined?

8. CanImakeitallsmallerandincreasetheinformationdensitywithoutdetract-
ingfromreadability? (Almostalways,yes.)
9. Ifthelayoutis complicated,haveIdrawnitout onpaperrst?
4 Margin space
Extra margins are usually wasted space and a break in the comparisons between
panels. You willalmost always want to shrink your margins. Set your margins for
eachpanelwithmarandyouroutermargins withoma. Ifalltheaxescanbeshared
thenset mar = c(0,0,0,0). Thesenumbersreferto the space onthebottom,left,
top,andright. Thenyoucanusepar(oma) toset youroutermarginsto create the
necessaryspaceforaxes. Ifyourcontentwon’tshowupintheoutermargins,you’ll
needtosetpar(xpd = NA).
5 Ways to iterate through your data
Common approaches are to use a for loop with subsetting or an apply function.

6 Basic multipanel layouts with par(mfrow)
For most basic grid layouts, par(mfcol) or par(mfrow) are your simplest option.
mfrowplotsrowbyrowandmfcolplotscolumnbycolumn. mfrowisthereforelikely
the most commonly used option. You’re going to give mfrow vector of length two
correspondingtothenumberofrows followedby thenumberofcolumns.
