Hi David,
Your code is showing up here with an arrow symbols. If it's an actual cut
and paste, that's your problem: assignment in R is the two-character <- and
not an arrow symbol.
Otherwise your code looks fine.

I've just uninstalled and then reinstalled R on my windows 7 machine.
To test my understanding of data frames, I'm trying the following code.
(I plan to do other things with it, if it would only work.)
Here's the code, which seems pretty basic to me:
ls()
nums ← c(1,2,3,4,5)
ltrs ← c(“a”,”b”,”c”,”
Thanks a lot for the reply!

Hi,
Sorry, a correction:

Question 1: How to get just 2 cumulative incidence curves when there are
multiple covariates.
I don't understand what you want. Assume that we have "liver transplant" and "death
while waiting for a transplant" as my two events. There are overall curves (2), or one
can create curves separate

I would add that:

I have several variables in a data frame that aren't listed by ls()
after I attach that data frame. Where did they go, and how can I stop
