R Biplot Example
- Below the result of just calling biplot: biplot(a) And now one can 'zoom in' to have a closer look at 'Murder' and 'Rape' using xlim and ylim and also use the scaling argument expand from?biplot: biplot(a, expand=10, xlim=c(-0.30, 0.0), ylim=c(-0.1, 0.1)) Please note the different scaling on the top and right axis due to the expand factor.
- A biplot is plot which aims to represent both the observations and variables of a matrix of multivariate data on the same plot. There are many variations on biplots (see the references) and perhaps the most widely used one is implemented by biplot.princomp.
Dear R-help fellows
good afternoon.
I am struggling in the attempt to impose some graphical conditions (changing point symbols, colors, etc) to biplot function (I am using it to visualize the results of princomp) but I can't apparently manage to change anything but the axis... and I have been browsing manuals and vignettes without finding any explicit suggestions on how to operate...
Can anyone, please, point my attention to the relevant documentation?
Thank you in advance and best regards,
Marco

For example there is a correlation between Unreliable and Here today, gone tomorrow. The biplot also allows us to see associations between the brands. For example Virgin mobile, Orange (Hutchison), AAPT, and New Tel each have similar response patterns, and are most strongly distinguished by Don’t know much about them.
