R - avoiding nested loops

Question

I know that for loops, you can avoid almost all the time in R if you understand the language correctly, but I'm struggling to find a smart way to do this

for (i in 1:100){ AllData[[i]]$Div = NULL } 

Where AllData is a list of 100 lists of various sizes. Can someone tell me?

Answer 1

Like this:

 AllData <- lapply(AllData, `[[<-`, "Div", NULL)
