Hi Folks,
I'd be grateful for suggestions about approaching the
following kind of data. I'm not sure what general class of

Where were you "reading about" that function?
simple.densityplot seems to be from a user-supplied package called "UsingR".
Try

Howdy,
In SPSS, there are 2 ways to weight a least squares regression:
1. You can do it from the regression menu.
2. You can set a global weight switch from the data menu.
These two options have no, in my experience, been equivalent.
Now, when I run lm in R with the weights= switch set accordingly,

Hello,
I have one more question. I looked through MASS.c file but I couldn't find
lda(...) function here. I expected that 'lda' function is a part of MASS source
code. Where can I find the source code for 'lda' - function?
Best wishes,
Alexey.

I cannot access internet through R.
My IT-guys told me that I should set the proxy and the port and then
everything will be fine. Where can I set them?
I use R 2.6.2 under Windows 2000 and these settings are those of the
Internet Explorer (no password).

Sorry, I missed the part about not having th leading zero. It is too
early yet with daylight savings time and no coffee so far.

You can also use sprintf:

[1] "0.44" "-0.22"

use %Y instead of %y in the format statement in
the split so that "2000" > "1999"; otherwise,

Hi there!
I have i.e. v = c(0.43554, -0.22343), and so on. Now I'd like to make a
format like
format(v, digits=2) but without the leading 0, so 0.43554 becomes .44,
-0.22343 becomes -.22
How can I do that?
runnable example for copy and paste:
v = c(0.43554, -0.22343)
format(v, digits=2)

I have the following problem: how appropriate is my aov model under the

Hi all,
I am trying to read a text file in R! I have a warning message:
In read.table(file = "data1.txt", header = T) : uncompleted last line of

Could you please tell me why? and how can I deal with missing value when I read
this file?
all the best

Dear R list,
again a newbie question here, so I wish I do not exasperated reader.

Hi Petr,
"barp" will compare the two columns displaying the values as heights of
bars.
"stackpoly" will display superimposed polygons, the upper edges of which
