Hi, that depends on whether you want to get the minimum within each list
element or the global minimum across all list elements. The first is
achieved by using lapply(). The second can be achieved by unlisting the list
(which assumes that all list elements are numeric) and looking for its
minimum.

x<-list(c(1,5),c(2,3,4))
lapply(x,min)
min(unlist(x))
