memory - 尝试使用众多组合功能，但都耗尽内存，如何定期写入输出以避免内存问题？

Question

"A" = seq(5,25,4)

"B" = seq(10,30,4) "C" = seq(5,15,2) "D" = seq(2,6,2) "E" = seq(0,2,1) "F " = seq(2,5,1) "G" = seq(1,5,1) "H" = seq(2,8,2) "I" = seq(0,6,2) "J" = seq(24,34,2) "K" = seq(0,12,2) "L" = seq(0,2,1) "M" = seq(4,10,2) "N" = seq( 0,4,2) dt6 <- data.table(A ,B,C,D, E,F,G,H,I,J,K,L,M,N) 有 13 个警告（使用 warnings()去看他们）

与（dt6，交叉（A，B，C，D，E，F，G，H，I，J，K，L，M，N））％>％

• filter(rowSums(.) == 100) 错误：无法分配大小为 7.0 Gb 的向量

write.csv(dt6,"C:\Users\M201967\Desktop\grid_out3.csv",row.names = TRUE) 交叉
