Request help writing a function
I have been wrestling with this function for quite a while, and am not making headway.
1) I want to apply a function to the following columns of a dataframe:
myfunction. <- apply(ph5028[,c(83:107)],2,function(x) ...
2) Within each of the above columns there is a single numeric code, 1, 2 or 3 or an NA.
3) My goal is to determine the percent of time each person used a 2 code. So if a person

Attempting to recode elements contained in a list
Hello R-Masters,
I have a list 's' with three elements, as shown below. I want to recode a.a, a.a2, and a.a3 to NA if the value in a.a is less than 3.
I reivewed my Modern Applied Statistic Book, the online help and did some searching of R-help on the internet. I explored unlist and as.list.data.frame in an attempt to isolate the third element of the list s, but this was not helpful.

Seeking help for outomating regression (over columns) and storing selected output
Hello,
I have spent considerable time trying to figure out that which I am about to describe. This included searching Help, consulting my various R books, and trail and (always) error. I have been assuming I would need to use a loop (looping over columns) but perhaps and apply function would do the trick. I have unsuccessfully tried both.
A scaled down version of my situation is as follows:

Would like to apply a weight variable to the summary function in Hmisc
Hello,
In the Hmisc package, functions describe and summarize can explicitly take a
weight variable.
My question is can a weight variable be applied when using 'summary'?
For example, using...summary(var1 ~ var2) I would like to weight the data
by var 3 (same length).
Is this possible?
Thanks a lot.

How to display each symbol in a different color using plot with summary.formula.reverse
Dear R Masters,
I have searched high and low (the help archives and my various R reference material and help files) for a solution to what appears to me to be quite a simple problem. In the following syntax, variable n10 has three levels. I would like the symbols that appear in the graph for these three levels to be different colors. The best I have been able to do is to have the Key display

contriburl argument to install.packages
Dear list members,
I can't figure out how to specify the contriburl argument to
install.packages() properly when the packages to be installed are in a
directory on my local machine. I have in mind a command something like
install.packages(missing.packages, contriburl=directory,
lib=.libPaths()[1])
Where missing.packages is a character vector of package names (without
versions) and
