我在R做一些扫把套装的练习。kclusts <- data.frame(k=1:9) %>% group_by(k) %>% do(fit=kmeans(data.frame, .$k))Error in as.vector(x, mode) : cannot coerce type 'closure' to vector of type 'any'
我在想我是不是漏掉了什么东西
children.push(c); j.join().expect("thread joining issue");}error[E0373]: closure may outlive the current function, but it borrows `i`, which is owned bythe current function
既然i的类型是i32,而且没有引用,那么R
