[R] Using lapply when there are dependencies

Hi all, Let's say I have a vector: vv<-c(1,2,3) And suppose I have a function f(a,b), which is a function of 2 scalar inputs. I would like to evaluate this function separately for each element of the vv vector while the second input to f( ) will be the previous output from f( ). So, the valu

Dear R users, I have a question regarding retrieving data from nested lists. To illustrate, here is an example input: d1<-data.table(v1=c(3,4),v2=c(2,5)) d2<-data.table(v1=c(1,2),v2=c(1,1))l1<-list(d1,name="test")l2<-list(d2,name="test2")motherlist<-list()motherlist$l1<-l1motherlist$l2<-l2 Let's s
