One option is mapply(), e.g.,
mylist <- list("v1"=c(1,2,2,1), "v2"=c(2,2,2,1), "v3"=c(1,1,1,1))
myvector <- c(100, 10000, 1000000)
mapply("*", mylist, myvector)
mapply("*", mylist, myvector, SIMPLIFY = FALSE)
I hope it helps.
Best,
Dimitris

hello everybody,
i have got a question about lists:
i have got the following commands:
mylist<- list("v1"=c(1,2,2,1),"v2"=c(2,2,2,1),"v3"=c(1,1,1,1))
myvector<- c(100,10000,1000000)
now i would like to multiply each element of the list with the corresponding
element of the vector, that is to say:
v1*100
v2*10000
v3*1000000
i only could think of lapply which can only be used to multiply each element
of the list with the same number, i think.
thank you very much in advance for your help,
marion
