OK, let's get started with some boring random numbers: \end_layout \begin_layout Standard \begin_inset ERT status open \begin_layout Plain Layout <>= \end_layout \begin_layout Plain Layout set.seed(1121) \end_layout \begin_layout Plain Layout (x=rnorm(20)) \end_layout \begin_layout Plain Layout mean(x);var(x) \end_layout \begin_layout Plain Layout @ \end_layout \end_inset \end_layout \begin_layout Standard The first element of \family typewriter x \family default is \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash Sexpr{x[1]} \end_layout \end_inset . Boring boxplots and histograms recorded by the PDF device: \end_layout \begin_layout Standard \begin_inset ERT status open \begin_layout Plain Layout <>= \end_layout \begin_layout Plain Layout ## two plots side by side (option fig.show='hold') \end_layout \begin_layout Plain Layout par(mar=c(4,4,.1,.1),cex.lab=.95,cex.axis=.9,mgp=c(2,.7,0),tcl=-.3,las=1) \end_layout \begin_layout Plain Layout boxplot(x) \end_layout \begin_layout Plain Layout hist(x,main='') \end_layout \begin_layout Plain Layout @ \end_layout \end_inset \end_layout \begin_layout Standard Do the above chunks work?
