string.
For example:
x-c(5/31/2009 12:34:00,6/1/2009 1:14:00)
I would like to remove the date and have just the time.
I have tried:
gsub([0-9+]/[0-9+]/[0-9+],,x)
Thanks for the help and the various options! Putting the + outside the
brackets worked, but I like the strsplit option. Always nice to learn new
functions!
Aloha,
Tim

Dear guRus:
I am using lmer for a mixed model that includes a random intercept for a
set of effects that have the same distribution, Normal(0, sig2b). This set
of effects is of variable size, so I am using an as.formula statement to
create the formula for lmer. For example, if the set of
Hello,
I'm trying to use the vcd package to analyze survey data. Expert judges
ranked possible features for product packaging. Seven features were
listed, and 19 judges split between 2 cities ranked them.
The following code (1) works, but the side-by-side plots for Cities PX,
SF are shrunk too
Could anybody point me to the latest status of the most user-friendly

How I wish I don't have to stare at my (long) code for ages and stuck...

Could anybody point me to some hands-on books about model selection,

Dear Jim,
Thanks for your suggestion.
I have a follow-up question for fellow R Users that have followed this thread:

decompose the two lists and do some case
I use barplot to plot graph, and there is axis of y, but no x, just label,
so where to add x-axis in barplot.

Dear R Users,
I have some dynamic selection rules that I want to pass around for my functions:
rules - paste(g$TrialList==1 g$Session==2)
myfunction - function(rules) {
index - which(rules)
anotherFunction(index)
}
However, I can't find a way to pass around these selection rules

If you are willing to go down one level and work at the grid level
then you can do it without modifying the panel function.
Below gg.ls$name lists the grid object names. Within that
list look at the ones that have rect in their name. Among
those are 5 in success (the 2nd through 6th rect
