我尝试使用cbind组合2个向量，两个向量大小相同，我运行代码时出错，向量很大，长度= 57605.
final=cbind (counts1,tx_by_gene)
> > Error: cannot allocate vector of size 225 Kb R(473,0xa0cb8540) malloc: *** mmap(size=233472) failed (error code=12)
> *** error: can't allocate region

> *** error: can't allocate region
> *** set a breakpoint in malloc_error_break to debug
任何人都可以帮助我，为什么我会遇到这个错误？或其他一些组合2个向量的方法？
谢谢

答案 0 :(得分：3)
对象tx_by_gene不是矢量。您可以使用is.vector功能
is.vector(counts1)
is.vector(tx_by_gene)
当然，可以定义方法，以便可以组合两个对象

这些向量对于R来说不应该太大。你可能在cbind()操作之前耗尽了大量内存。使用ls()查看您目前拥有的对象，并使用rm()删除不再需要的对象。
