Hello,
I'm following an example in the book, analyzing baseball data with R, but
it's not working for me. The example is:
compute.hr <- function(pid){d <- subset(Batting.60, playerID==pid)
sum(d$HR)}
Every time I try this, it says there's an unexpected symbol. Any idea on
what the unexpected symbol is or how to fix it? Thanks.

Hi Alexander, I suspect that when you write "try" you mean that you try to run the function with some value for "pid". The "unexpected symbol" error message usually includes the offending symbol and that will probably identify the problem.
