Hi,
I tried to use naivebayes in package 'e1071'.
when I use following parameter, only one predictor, there is an error.
m - naiveBayes(iris[,1], iris[,5])

Ok, I think I've got it this time.
The problem was that you have two different types of data in the same data
structure,
the first row are the result's column names, then the actual numeric data.
First, in what follows I've called your data.frame 'df1',
df1 - structure(list(A2 = structure(c(9L,

Dear all,
I have a MA plot for replicate single channnel arrays, the loess curve is
aligned to M=0. However, I expect that M values be as close as possible to
M=0 for replicate arrays, which is not the case. How may I obtain a measure
that indicates the average distance of points to M=0?
Given your starting values, there is nothing to optimize:
f - function(x, A=10, b=152, T=100, c=100) A*(1-exp(-b*(x-T) -
c*(sqrt(x) - sqrt(T

What's the big picture of what you're trying to do? eval(parse(text

Some guesses:
Are you trying to construct a formula object (in the strict sense of
something that you pass to a modeling function)?
Maybe lazy evaluation of the deparse(substitute(x))
I think that if you're not familiar with emacs or vim I suggest you to
use RStudio. If you're a programmer that knows how to use eclipse I think
eclipse with statet it will be the best solution. Another option that you

The alarm() function just sends a ctrl-g (ASCII BEL character) to the console
terminal. If the terminal type recognizes this byte according to that
interpretation, and it is not locally configured to disable sound, then you
should hear an audible alert. Linux consoles typically do handle this.

My guess is that somewhere you've accidentally redefined c to be

Open the Terminal and type

this will start R totally clean and then try
