Help in using PCR
Hi,
Currently I have a dataset of 2400*408. And I would like to apply PCR method
to study the any correlation between the tests.
My current data is in data.frame and I have formed horizontal(1-407) to be
the exact data, and (408) to be my results data(Yes and No)
I have also binarized these Yes and No to 1 and -1s.
However, when I refer to PCR manual on R, the example of yarn.pcr <-

spaghetti plot - urgent
Hi everyone,
I?m trying to do a spaghetti plot and I know I?m doing all wrong, It must be.
What I need:
15 subjects, each with measurements over 5 different times (t1, ..., t5), and the variable that I need to represent in the spaguetti plot is given by:
PCR = b0 + b1 * ti + epsilon
B0, - baseline of each subject
B1 - trajectory of each subject over time (so multiply by t)
Epsilon - error

spaghetti plot - urgent
Hi Rosa,
You pass a vector to ggplot, which expects a data.frame. I am sure you
meant to do this:
point7$y_point7 <- point7$beta0_7 + point7$beta1_7*point7$time + point7
$epsilon_7
ggplot(point7, aes(time, y_point7)) + geom_line()

R graphs in LaTeX documents?
I have tried to find a neat way to include graphs from R in LaTeX documents,
but have not succeeded (I work with a WinEdt/MikTeX combination). The two
roads I have stumbled along so far are the following:
*Generate postscript files and convert them into EPS files by means of
GhostScript or other not so straightforward tools.
*Generate pictex files and include these.

What has been swapped out?
I have a SunRay server that I am looking at to determine some sizing requirements in my department. The machine has 16G of ram and 10G of swap. Currently, I have about 4G of swap used. I am wondering if dtrace/mdb can be used to find out what lwp/processes have been swapped out?
Any hints?

Predicting with a principal component regression model: "non-conformable arguments" error
Hello all,
I have generated a principal components regression model using the pcr()
function from the PLS package (R version 2.12.0). I am getting a
"non-conformable arguments" error when I try to use the predict() function
on new data, but only when I try to read in the new data from a separate
file.

problem with pls(x, y, ..., ncomp = 16): Error in inherit s( x, "data.frame") : subscript out of bounds
I don't know the details of pls (in the pls.pcr package, I assume), but if
you use validation="CV", that says you want to use CV to select the best
number of components. Then why would you specify ncomp as well?

computation with vectors of length 0 (PR#2716)
Full_Name: Klaus Hermann
Version: 1.5.0

Submission from: (NULL) (213.61.59.254)
if we produce a numeric vector of length 0 and want compute the sum over its

the sum function returns 0 - this is obviously misleading. Better would be to
return
NA and give a corresponding warning.
There should be a unified strategy to handle vectors of length 0.

loadings matrices in plsr vs pcr in pls pacakage
Dear list,
I have a question concerning the above mentioned methods in the pls

some work I am doing I have found that the values produced are nearly of
the same magnitude but of opposite sign. When I use the example data
(sensory) I find this result reproduced. I am prepared to work this
through but I have a feeling that

center or scale before analyzing using pls.pcr
Dear all,
I found pls.pcr package will give different results if the data are
centered and scaled using scale().
I am not sure about when I should scale my data, and whether the
dependent variable should be scaled. If the dependent variable is
scaled, how I give a prediction to the real data?
I appreciate for any suggestions and comments.
Best regards,
