The loop constructs will keep you mired in SAS-brain

Plz provide a reproducible example (using dput).
Anyway, I suspect your data to be 'factor' and not numeric.
y=rbinom(100,1,0.5)
x=runif(100)
plot(x,y) #OK
plot(x,as.factor(y))
See ?factor and ?as.numeric.

Hello,
Anyone know why the

if you really wants to use this code.

You did not specify any object in the function. Thus R is building the
package test with all the objects present in your session when you are
calling the package.skeleton function. I suppose that one of these
objects is causing problem. I suggest you list all the
variables/function necessary
See ?sparseMatrix from package Matrix.

Dear R people.
I´m facing a big problem.

Hello,
When i generate data with the code below there appear NA as part of the
generated data, i prefer to have zero (0) instead of NA on my data.
Is there a command i can issue to replace the NA with zero (0) even if it is after generating the data?
Thank you

plot(dend1, xlab='',ylab='',sub='', nodePar=list(pch = c(1,NA), cex=0.8,

See ?plot.hclust and ?plot.dendrogram. They are not using the same

Hi Chris,
I personally found the documentation rather...indigestible. At least 3
years ago when I developed my R package. It seems they have nicely
improved this part of the documentation though.
I'm not an expert at all, but at least you will have the point of view
of a beginner.
