R help - Mar 2011 - applying to dataframe rows

How do I apply a function to every row of a dataframe most naturally? 
Specifically, I'd like to filter out any row which contains an Inf in any
column.  Since all columns are numeric, I guess max should work on a row...

Hi,

maybe this:

df<-data.frame(a=c(1,2,3,Inf,4,Inf),b=c(Inf,2,3,4,5,8))

df[apply(df,1, function(x) !any(x==Inf)),]
df[apply(df,1, function(x) any(x==Inf)),]
