Frequency table to histogram
I have read a frequency table in to R called "temp." I now want to create a histogram table from it, but I obviously first have to expand the data - to the sample size of 100. I want to use the command rep(), but I'm not sure how to go about it..I tried using the code:
temp1<-rep(temp$Chest,100)
hist(temp1)
But this creates a v. odd histogram so I know it must be wrong!

"taking the log then later exponentiate the result" query
Hi,
I am trying to figure out the observed acceptance rate and M, using generalised rejection sampling to generate a sample from the posterior distribution for p.
I have been told my code doesn't work because I need to "take the log of the expression for M, evaluate it and then exponentiate the result." This is because R is unable to calculate high powers such as 545.501.

axis thickness in plot()
Hello,
I am trying to increase the thickness of the axis in plot() without
reverting to the use of paint programs
i see posts on that topic for the xyplot function but want to see if i can
do it with plot() because i've already setup my graph script using that
i thought i could use axis() function and specify lwd="thickness" or
lwd.axis= but that does not work like it does for

replace elements in a list
Dear all, I have a list like this: l <- list(list(a=1,b=NULL), list(a=2,b=2))
I want to find out the elements with value of NULL and replace them with NA.
The actual case has a very long list, so manually find out and replace
them is not an option.
I can use for loop to do this, but I want to know if there is
vectorized way (or other ways) to do it?
Thanks

Visualization of coefficients
Dear all,
I try to show a subset of coefficients in my presentation. It seems

Example scripts for R Manual
Hi,
I am wondering if some experienced users would help put the
ready-to-run code of the examples in the manuals. It would help new
users learn R faster by putting all the examples in an ready-to-run R
script file. Can somebody help do so sometime and post the code along
with the pdf manuals?

Urgent - odfWeave produces graphs /images with Read-Error
Dear list,
I have been working on a report with around 60 images in it, and
everything has been fine, until now. I find that the image output that
is produced by odfWeave produces images that are NOT readable by
OpenOffice or NeoOffice. I get empty boxes with Read-Error written in
them. While generating the file using odfWeave, I can see them being
generated on the screen, and they all seem fine.

Removing objects from workspace
Hi all,
I am currently woking with hundreds of objects in workspace and whenever I
invoke ls() to observe the names of the objects, there are too much of
unnecessary variables.
For example, if I only require say 3 or 4 objects from hundreds of objects
in workspace, are there any methods that may do the job?
I have tried rm(-c(x,xx,xxx)), but no luck..
