regrouping factor levels
Hi all,
I had some trouble in?regrouping factor levels for a variable. After some experiments, I have figured out how I can recode to modify the factor levels. I would now like some help to understand why some methods work and others don't.
Here's my code :
rm(list=ls())
###some trials in recoding factor levels
char<-letters[1:10]
fac<-factor(char)

Regrouping data
Dear R forum
I have just started my venture with R. While I am trying to learn R through the tutorials, I think the current problem I need to address to is beyond my knowledge about R.
I have a dataframe as defined below -
rat_dat = data.frame(name = c("A", "A", "A", "B", "B", "B", "C", "C", "C",

problems while correlating values
Hi,
I am a newbie to the world of R.
I have a data converted in csv format. Few cells in
some of the rows of the data are blank ( in the sense
that there is no value available for the particular
experiment). When i try to open the file in R. I get
an warning message.
The specific warning message i get is
{Warning message:
NAs introduced by coercion }

Inversions in hierarchical clustering were they shouldn't be
Hi,
I''m using heatmap.2 to cluster my data, using the centroid method for clustering and the maximum method for calculating the distance matrix:

factor creation
Another newbie question....
I want to create a factor (say cT)from a numerical variable (sy temp) by
regrouping the values in classes (say cT <390, [390,400[,[400,409[...>=550)
Is there a simple way of doing that using the factor function?
AND I do not find how to manipulate strings (I want to concatenete characters

transformation of data.frame
Hello all R users,
I have a problems transforming (or maybe better regrouping) a data.frame.
I have a big data.frame, which I would like to sum up according to a
specific column.
This is an example of my matrix:

0016070 gen2
0016070 gen3
0007409 Gen1

dotplot as a background for multiple barchart plots (with Lattice)
Hi R users,
I'm kind stuck in my R experience...
I want to have a multiple barchart with n windows, but with the same
background for each window, and I want that background to be a recorded
dotplot.
First, is it possible ?
If so, I guess I have to call a record plot in the panel function but how ?
As there is no panel.plot and I can't use the recorded plot as an
argument for the

testing parallel slopes assumption for Ordinal Logistic Regression
Hi everyone, I'm a bit new here (and new to R), and I was trying to do an
OLR, and testing the parallel slope assumption seems be very important. I
browsed through past postings, and didn't find much to help me in this area.
I was wondering if anyone knew how I could go about doing this. Thank you.

Regroup and create new dataframe
Responses should be copied to r-help using ReplyAll. You are still sending html formatted emails. If you are using Microsoft Outlook, click the Format Text tab and select ?Aa Plain Text?. No one has asked you to reveal the data set, only to create one with a similar structure. Is the data I sent reasonably close? What should it look like after it is transformed?

Hello folks,
I have a big project to work on and the dataset is classified so I am just

Let's take Target as an example: We consider three brands of tape: Target
brand, 3M and Avery. The original data frame has 4 columns: Year of Record,
Product_Name(which contains three brands of tape), Sales, and Region. I

USB ports on Lenovo T400 do not work after a suspend/resume
Hi,
FreeBSD-9 works fine on this Lenovo T400 - except that suspending with
no USB devices plugged in result in no ports working after resume.
If I have a device plugged in during suspend - on any port - then all
the ports work fine after resume.
I've attached usbconfig and acpidump output.
here's what is logged in the kernel buffer during suspend and resume:

Reordering a numeric variable
I'm running a linear model in R using the car package.
I have a variable education, which i have recoded and regrouped to my
wishes.
However, R seems to place each element of that variable in alphabetical
order.
When I am running the model, don't I need the model order from lowest to
highest to make an inference that

Mancova with R
Dear all,
I'm trying to compare two sets of variables, the first set is composed exclusively of numerical variables and the second regroups factors and numerical variables. I can't use a Manova because of this inclusion of numerical variables in the second set. The solution should be to perform a Mancova, but I didn't find any package that allow this type of test.
I've already
