summary.manova rank deficiency error + data
Dear R-users;
Previously I posted a question about the problem of rank deficiency in

the data set.

index.cond in xyplot
Dear R-users
I have 5 dependent variables (y1 to y5) and one independent variable (x) and
3 conditioning variables (m, n, and 0). Each of the conditioning variables
has 2 levels. I created 2*4 panel plots.
xyplot(y1+y2+y3+y4+y5 ~ x | m*n*o,layout = c(4,2))
I would like to reorder the 8 panels. I tried to use index.cond (e.g.,
index.cond = list(c(1,3,2,4,5,7,6,8)) but it didn't work out.

mfrow
Dear members,
I want to create 8 graphs and write it into one page using mfrow=c(4,2).
How to make all graphs (including the titles, legends, line types) to be
scale down (resized proportionally).
As an illustration, below is the code:
pdf("testmfrow.pdf")
par(mfrow=c(4,2))
x<-seq(1:10)
y1<-rnorm(10)
y2<-rnorm(10,mean=2,sd=1)
y3<-rnorm(10,mean=3,sd=1)

[R-pkgs] New package: `lavaan' for latent variable analysis (including structural equation modeling)
Hi Yves
lavaan looks like a very nice package. From the tutorial introduction
I see you create path diagrams for some of the models you describe.
How did you do this? I don't see a function for this in the package.
I know there is a path.diagram function in the sem package that uses
dot to draw the diagram, but I've always found the layouts from dot
somewhat strange for path diagrams

help with a regression
Hello, I have a data frame with the following variables:
ID, X1,X2,X3,X4,X5,Y1,Y2,Y3,Y4,Y5 and some other that do not matter, some of the X and Y can be missing (NA). I want to compute the slope of the linear regression Y ~ X for each subject, so using
apply(DF,1,FUN,ra.rm=TRUE) now How do I define FUN? The X are different for each subject.
Thanks for any help

GLM question
I am unfamiliar with R and I’m trying to do few statistical things like GLM and GAM with it. I hope my following questions will be clear enough:
My datas ( y(i,j ))are run off triangles for example :
J=1
J=2
J=3
I=1

I=2

My model is :
E[y(i,j)] =m(i,j)
Var[y(i,j)] =constant *m(i,j)
Log(m(i,j)) = eta (i,j)
eta (i,j) = c + alpha(i)

RMySql inserts \r when using dbWriteTable

cbind, data.frame | numeric to string?
Complete newbie to R -- struggling with something which should be pretty
basic. Trying to create a simple data set (which I gather R refers to as a
data.frame). So
> a <- c(1,2,3,4,5);
> b <- c(0.3,0.4,0.5,0,6,0.7);
Stick the two together into a data frame (call test) using cbind
> test <- data.frame(cbind(a,b))
Seems to do the trick:
> test

I have a dataset with multiple columns. Some of the columns represent
independent variables, some represent dependent variables. I would like
to run the same analyses on a fixed set of independent variables,
changing only the dependent variable, e.g.

sampling from data.frame
Hi all,
I have a data frame with "clustered" rows as follows:
Cu1 x1 y1 z1 ...

Cu2 x4 y4 z4 ...
Cu2 x5 y5 z5
Cu2 ... # end of second cluster Cu2

"cluster"-size is 3 in the example above (rows making up a cluster are
always consecutive). Is there any faster way to sample n clusters

When bootstrapping a statistics based on more than one vector, from a

I use the library "bootstrap".
Here is an example with a data.frame called "data"

plotting the regression coefficients
Fwiw, encoding magnitude in color is generally a bad idea. Using area(*not*
radius) is also not great, but maybe it will work for you.

plotting the regression coefficients
Hi Dear all;
I would like to create a plot for regression coefficients with each
independent variable (x) along the side and the phenotypes (y) across the
top (as given below). For each data point, direction and magnitude of
effect could be color and significance could be the size of the circle? Is
this possible?
I would greatly be appreciated your help.
Thanks,
Greg
