解释这行代码library(groupdata2) res_list <- list() for(i in 1:times){ res_list_tmp <- partition(data=inputArr, p=partition1_size, cat_col=cat_col, num_col=num_col, id_col=id_col) names(res_list_tmp) <- c("train", "validate") res_list[[i]] <- res_list_tmp }

这段代码首先引入了 R 语言中 groupdata2 库,然后定义了一个空的列表 res_list。接下来进入循环,循环次数为 times。在每次循环中,调用 partition() 函数对输入数据 inputArr 进行划分,其中 p 参数指定了每个子集的大小,cat_col 参数指定了分类变量的列名,num_col 参数指定了数值变量的列名,id_col 参数指定了 id 变量的列名。划分后的训练集和验证集存储在 res_list_tmp 中,然后将其命名为 "train" 和 "validate",最后将 res_list_tmp 添加到 res_list 中。循环结束后,res_list 中存储了 times 个划分好的训练集和验证集。
