infinite-recursion

问题 Intuitively, I would expect the "mathematical" answer to all (==1) [1,1..] to be True because all of the elements in a list that only contains 1s are equal to 1. However I understand that "computationally", the process of evaluating the infinite list in order to check that each element does in fact equal 1 will never terminate, therefore the expression instead "evaluates" to bottom or ⊥ . I find this result counter-intuitive and a little unnerving. I think the fact that the list is an

问题 I'm trying to use a function in order to read in different models. Using the code below without a function works. When I use the function and call it, I will get the error Error: evaluation nested too deeply: infinite recursion / options(expressions=)? Can anyone tell me why? x=rnorm(1000)+sin(c(1:1000)/100)#random data+ sinus superimposed plot <- function(model){ par(mfrow=c(2,2))# plot window settings plot(model) lines(filter(model,rep(1/30,30)),col='red') plot(filter(model,rep(1/30,30)))

问题 First, here are my entities. Player : @Entity @JsonIdentityInfo(generator=ObjectIdGenerators.UUIDGenerator.class, property="id") public class Player { // other fields @ManyToOne @JoinColumn(name = "pla_fk_n_teamId") private Team team; // methods } Team : @Entity @JsonIdentityInfo(generator=ObjectIdGenerators.UUIDGenerator.class, property="id") public class Team { // other fields @OneToMany(mappedBy = "team") private List<Player> members; // methods } As many topics already stated, you can
