Hi! This is going to be a real newbie question, but I can't figure it out.
I'm trying to plot densities of various functions of chi-square. A simple

only know how to do using density(rchisq()/df). For example:

Thanks, but that wasn't what I was going for. Like I said, I know how to do a

How do I do that with dchisq?

I am using numerical method for my research paper and the computation burden is

OK, for the record, this is not my homework, thanks for asking!
Also, I am sure I could have phrased my question more eloquently, but (hence
the newbie qualifier) I didn't. The code I posted was for the plot I want,
only smoothed i.e not based on random sampling from the distribution.

Hello,
Setup: I have data with ~10K observations. Observations come from 16
different laboratories (labs). I am interested in how a continuous factor,
X, affects my dependent variable, Y, but there are big differences in the
variance and mean across labs.
I run this model, which controls for
One difference is that the random effect in lmer is assumed --
implicitly constrained, as I understand it -- to
be a bell curve. The fixed effect model does not have that constraint.
How are the values of labs effects distributed in your lm model?

Hi all,
I'm trying to plot this two curves in a single cartesian plane, but when I

Hi Stephen,
Maybe it is just me, but I am not clear what your question is. scan()
is a function with a variety of arguments. When these are not
explicitly named, they go in order. So, scan(1, 2, 3, 4, 5) is
equivalent to scan(file = 1, what = 2, nmax = 3, n = 4, sep = 5),
which is clearly

Hi Rookie,
Just as a note, it is generally nicer if you just provide the list
with some sample data that illustrates your problem. This should
answer your question:

mymatrix - mymatrix[, -1] #remove column 1

Hi Rookie,
Sure, just use the dimnames argument. You pass it a list where the
first element contains the row names and the second element contains
the column names. Supposing you only want to name one dimension, just
use NULL for the other (see ?matrix for full details).
Using your data:

Hi,
Here are two options. Depending whether the data is already read in
or being created, one or the other may be more useful to you
###
x1 - matrix(1:4, ncol = 2)
colnames(x1) - c(First, Second)
#OR
x2 - matrix(1:4, ncol = 2, dimnames = list(NULL, c(First, Second)))

Try this:

You are the only one who can tell whether the p-values are actually predictions
