For base graphics, 'thigmophobe.lables' in the plotrix package also works to
avoid label overlap.

The xlabs= (rows) and ylabs= (columns) arguments handle the labels, but they do
not recycle so you need to specify values for each row and each column:

Dear all;
I did biplot in R. How can I interpret them in order that i can create two
or more groups in each biplot. I wanna determine the variables that have
the same origin.
please help me.
many thanks.

Hello,
I am doing a principle component analysis on a dataset with a lot of
different variables and have constructed a biplot of the data.
Unfortunately, as can be seen on the attached image, the biplot is very
messy, cluttered, and hard to read. I have performed a few modifications
including

Hi everyone,
I am doing PCA with labdsv package. I was trying to create a biplot graphs
in order to observe arrows related to my variables. However when I run the
script for this graph, the console just keep saying:
*Error in nrow(y) : element 1 is empty;
the part of the args list of 'dim' bei
Probably so that the end of the arrow does not overplot the labels.

Dear forum,
I need to create biplot graphic. I took a look at the code of the
biplot.default function from the stats package and I found that the arrows for
the variables are multiplied by a coefficient of 0.8 before plotting:
...
if (var.axes)
arrows(0, 0, y[, 1L] * 0.8, y[, 2L] * 0.8,

Hi, You can make a biplot on Your own, it is not so hard. And in this
case You can change parameters for every low level function as You
wish.
PC <- prcomp (iris[,1:4])
lambda <- PC$sdev * sqrt(nrow(PC$x))
plot (t(t(PC$x)/lambda),pch=16,col=as.numeric(iris[,5]))
par (new=T)
Rot <- t(t(PC$rotation)

Dear R-help fellows
good afternoon.

results of princomp) but I can't apparently manage to change anything but the

How exactly do you want to connect them? One approach is:
qplot(V1, V2, data=f, colour=date) + geom_path()
# or maybe
I would like to connect the dots based on when they occur in time. Is
there an easy way to do this?
thanks

That's not how biplot.defa
Also check the asp= parameter in plot.default and plot.window; this sets
the aspect ratio so that 1 unit in x is the same physicla length as 1
unit in y. I don;t know whether it is respeced by your particular

Hi,
I am wondering how to draw biplot with the same scales on both plots?
For example, if the two plots have much different scales, generally
the two x-y's are scaled so that the two plots are sitting in the
center automatically. How to disable this?
Thanks
