That's because the parser knows how to deal with that stuff. However,
when you type the same if/else at the command line, it will be parsed

Hello,
Hi all,
I created a plot function which used par(mfcol=c(2,1)) so that I could
have two plots together using just one command.
For exampe:
plot.foo - function(data){
par(mfcol=c(2,1))
hist(data)
plot(data)
}
Later I wanted to show 4 of these foo objects in the same picture. So
I used
see the row.w argument of the function dudi.pca in the ade4 package.
Cheers.

I'm trying to do a weighted principal components analysis. I couldn't find any
such option with princomp or prcomp. Does anyone know of a package or way to
do this?

I'm not sure what you are doing when you Normalize. Would you explain?
To see if the slope is significant, look at the model summary, in your
example:

For science yes. For pleasure I'll still take a pint instead of 570ml!

Hello R community,
I have cross-posted with r-sig-geo as this issue could fall under either
interest group I believe.
I just came accross the alphahull package and am very pleased I may not
need to use CGAL anymore for this purpose. However, I am having a
problem computing alpha shapes

And you might experience a disappointment then if you order it in the
US where the pint is apparently 450ml; at least, I won several
97 matches
