list as object in dataframe
Hi All,
I need to place lists or vectors within dataframes as single
elements. However when I try this:
df=data.frame(y=1, x=I(list(c("a","b"), c("f","c"), c("a"))))
df
df[1,'x']=I(c("a","d"))
I get this error, even though I am using I():

adding error bars to lattice plots
Dear R users,
About a year ago Deepayan offered a suggestion to incorporate error bars
into a dotplot using the singer data as an example
<<http://finzi.psych.upenn.edu/R/Rhelp02a/archive/63875.html>>.

stating that the subscripts argument is missing. I have tried to insert
them in various ways, but cannot

passing arguments to functions within functions
Dear R Users,
I am trying to write a wrapper around summarize and xYplot from Hmisc
and am having trouble understanding how to pass arguments from the

There must be a way, but I have not been able to figure it out.
An example is below.
Any advice would be greatly appreciated.
Thanks, Dan
