Hi R users:
I got an error that "l1" is not found.
This is a sample code:
f1<-function(i,l1){
print(l1[[i]])
l1[[i+1]]<<-i
return(i)
}
z1<-list(x=100,NULL,a=c(1,1))
lapply(1:3,f1,l1=z1)
My final goal is to update the value of
each list component to use it in the following
step.
I see that print function founds l1[[1]],
but the assign instruction not.
Thank you for your help.
Kenneth

Yes... It assing to each list component the index... As you see I want to modify each component of the list so I can use it at the following step o the lapply procedure.
