[R] Help for par(mfrow)

[ctu at bigred.unl.edu]

Hi, R users
I have a question with par(mfrow). I try to histograms and qqplots  
form boot output for 5 statistics but par(mfrow=c(5,2)) or  
par(mfrow=c(5,1)) does not work. R still display each figure  
separately. What did I do wrong? (I check ?par)
> c1.boot<-boot(c1data,c1.fun,R=999)
> c1.boot

ORDINARY NONPARAMETRIC BOOTSTRAP
Call:
boot(data = c1data, statistic = c1.fun, R = 999)

Bootstrap Statistics :
