Re: [R] list objects calculation

Hi you maybe can use mapply If you have 2 lists xl<-list(x, x+5) xl [[1]] [1] 1 2 3 4 5 [[2]] [1] 6 7 8 9 10 > yl<-list(9,10) > yl [[1]] [1] 9 [[2]] [1] 10 and this function fff<- function(xl,yl) (xl-yl)/yl mapply(fff, xl, yl) [,1] [,2] [1,] -0.889 -0.4 [2,] -0.778

[R] list objects calculation

I have two kinds of list, for example, one is like t[[1]]= 1 6 2 7 3 8 4 9 5 10 ... t[[731]] the other is k[[1]]= 9 10 ... k[[731]] I want to have a new list,like x x[[1]]= (1-9)/9(6-10)/10 (2-9)/9(7-10)/10 (3-9)/9(8-10)/10 (4-9)/9(9-10)/10 (5-9)/9(10-10)/10 ... x[[731]] How s
