regarding 3d Bar Plot

it can be interpreted as like this A - I are the matches and P - X are
the players. Thus Player P scored 20% of the runs during this season in
Match C, 60% in Match D and remaining 20% in Match G.

Removing a list of Objects
Hi,
I have a simple beginner's question on removing a list of
objects. Say I have objects C243.Daily1, C243.Daily2...C243.Daily5 in my
workspace. I'd like to remove these without using rm five times.
So I write.
> a <- list(paste("C243.Daily",sep="",1:5))
> rm(a)
Obviously this wouldn't work, as it would only remove the object a.
But is there any way

reliability, scale scores in the psych package
Dear Professor Revelle and R-helpers,
This is a two-part question: the first part is general, and the second
is specific to the psych package.
First question: In the past I've constructed composite variables from
questionnaire data by using rowMeans(), and then correlating items
with the scale using cor() as an informal check for "bad" items. Over
the weekend I decided to take a

regarding 3d Bar Plot --- correction.
I mis-spoke. It seems I had two collections of functions in the same
directory. One by Colin Goodall, and one by David Scott (I have no
record of where he is/was located). It is the *latter* collection
that does all its work from within Fortran.
I'll have another look at what Colin Goodall actually wrote to see if
it could be useful to guarav.
