Dear list, I read in ?plotmath that I can use bgroup to draw scalable delimiters such as [ ] and ( ).

Dear All, I am sure this is a one-liner, but I cannot find the R command to generate the LaTex symbols \perp and \parallel. Consider for instance the figure (one can use any kind of data for the plot) pdf("friction_linear_chain_perpendicular.pdf") par( mar = c(4.5,5, 2, 1) + 0.1) plot(data[ ,1], data[
