Removing white space around R figures

Published on 22 February 2013

When I want to insert fig­ures gen­er­ated in R into a LaTeX doc­u­ment, it looks bet­ter if I first remove the white space around the fig­ure. Unfor­tu­nately, R does not make this easy as the graphs are gen­er­ated to look good on a screen, not in a doc­u­ment. There are two things that can be done to fix this problem.

Man vs Wild Data

Published on 21 December 2012

I’m speak­ing on this topic at the Young Sta­tis­ti­cians Con­fer­ence, 7–8 Feb­ru­ary 2013. If you’re a young sta­tis­ti­cian and live in Aus­tralia, please book in. It promises to be a great cou­ple of days. Early reg­is­tra­tions close on 2 Jan­u­ary. Abstract for my talk: For 25 years I have been an intre­pid sta­tis­ti­cal con­sul­tant, tack­ling the wild fron­tiers of real data, real prob­lems and real time con­straints. I have faced prob­lems rang­ing from lin­guis­tics to river beds, from mak­ing paper plates to sell­ing pies at the MCG, from tax office audits to sur­veys about the colour pur­ple. Uni­ver­sity edu­ca­tion helps pre­pare you to be a sta­tis­ti­cal con­sul­tant in the same way that Google maps helps pre­pare you to cross the Simp­son Desert. You have some idea of the main fea­tures, but when you get there, noth­ing looks famil­iar. I will describe some of my adven­tures, and explain how to bluff your way through igno­rance, work with inad­e­quate tools, and deal with smelly clients. I will tell you the story of the client who wouldn’t give me the data, the client who wouldn’t tell me the prob­lem, and the client who wanted all meet­ings held at ran­dom loca­tions for secu­rity rea­sons. Along the way we will learn about the skills

Bare bones beamer

Published on 1 August 2012

Beamer is far and away the most pop­u­lar soft­ware for pre­sen­ta­tions amongst researchers in math­e­mat­ics and sta­tis­tics. Most con­fer­ence and sem­i­nar talks I attend these days use beamer. Unfor­tu­nately, they all look much the same. I think peo­ple find beamer themes too hard to mod­ify eas­ily, so a small num­ber of tem­plates get shared around. Even the oth­er­wise won­der­ful LaTeX Tem­plates site has no beamer exam­ples. The beamer user guide explains how to make changes but it is not for the faint-​​​​hearted (although it is a fan­tas­tic resource once you have some exper­tise). So I thought it might be use­ful to pro­duce a very sim­ple beamer tem­plate that is easy to extend and modify.

Data visualization videos

Published on 30 November 2010

Prob­a­bly every­one has seen Hans Rosling’s famous TED talk by now. If not, here it is: I recently came across a cou­ple of other excep­tional talks on data visu­al­iza­tion: Hans Rosling again: “Let my dataset change your mind­set”. If only all sta­tis­tics lec­tur­ers were this dynamic! David McCan­d­less: “The beauty of data visu­al­iza­tion”. Not so excit­ing as Hans, but some great exam­ples. And here’s an hour-​​​​length doc­u­men­tary hosted by Hans Rosling called “The Joy of Stats”.

Animated plots in R and LaTeX

Published on 13 October 2010

I like to use ani­mated plots in my talks on func­tional time series, partly because it is the only way to really see what is going on with changes in the shapes of curves over time, and also because audi­ences love them! Here is how it is done.

Attending research seminars

Published on 14 October 2009

Most research stu­dents don’t seem to attend sem­i­nars. When asked, they usu­ally say the sem­i­nars are not on their topic, or they don’t under­stand them, or they find them bor­ing, or some other sim­i­lar rea­son. I think this is because stu­dents don’t under­stand the pur­pose of research sem­i­nars, and have not learned how to lis­ten to them. Admit­tedly, many research sem­i­nars are badly pre­sented, and sem­i­nar speak­ers also fre­quently mis­un­der­stand the pur­pose of the sem­i­nar, which makes the prob­lem worse. In a pos­si­bly vain attempt to improve the sit­u­a­tion, here are some thoughts on attend­ing research sem­i­nars. First, some advice to speak­ers: under­stand that sem­i­nars are intended to pro­vide brief and infor­mal tasters of a wide range of research. Peo­ple will get the detailed and for­mal ver­sion of research in the pub­lished papers. But often an infor­mal expla­na­tion with­out the details is more acces­si­ble. Also, a speaker can pro­vide the back­ground overview that is often miss­ing in the pub­lished papers. Speak­ers need to realise that there is no need to present detailed proofs, tables, and tech­ni­cal­i­ties — a sem­i­nar is a very poor medium for pro­vid­ing details about sta­tis­ti­cal and econo­met­ric research. You have given a suc­cess­ful sem­i­nar if every­one in the audi­ence has some idea about what

The 7 secrets of highly successful PhD students

Published on 28 September 2009

It seems every­one has 7 secrets to suc­cess, and now some­one has hopped on the 7-​​​​secrets band­wagon with some­thing for PhD stu­dents. Thinkwell is an Aus­tralian com­pany offer­ing a sem­i­nar and asso­ci­ated work book on “The 7 secrets of highly suc­cess­ful PhD stu­dents”. I bought the book out of curios­ity, but “book” is a gross exag­ger­a­tion — only eleven pages of fairly sim­plis­tic advice. I hope the sem­i­nar has more sub­stance. For what it’s worth, here are the so-​​​​called seven secrets. Care and main­te­nance of your super­vi­sor. Write and show as you go. Be real­is­tic. Say no to dis­trac­tions. It’s a job. Get help. You can do it. If you can work out what is meant from those head­ings, you’re doing bet­ter than me. After read­ing the “book”, I think a bet­ter sum­mary would be as fol­lows. Meet reg­u­larly with your super­vi­sor. Write up your research ideas as you go. Have real­is­tic research goals. Beware of dis­trac­tions and other com­mit­ments. Set reg­u­lar hours and take hol­i­days. Make full use of the avail­able help. Per­se­vere. Noth­ing too sur­pris­ing there. Per­haps it should have been called “Seven obvi­ous things PhD stu­dents should already know”. If I haven’t put you all off, one of the authors is pre­sent­ing the sem­i­nar at Monash in a cou­ple of weeks. The
