加载大型RData文件

Question

我无法加载RData文件，我收到以下错误消息

> load("GPL570_matrix.Rdata")
Error: cannot allocate vector of size 8.9 Gb
In addition: Warning messages:
1: Reached total allocation of 5941Mb: see help(memory.size) 
2: Reached total allocation of 5941Mb: see help(memory.size) 
3: Reached total allocation of 5941Mb: see help(memory.size) 
4: Reached total allocation of 5941Mb: see help(memory.size)

我尝试使用

增加内存限制

memory.limit(size=11264)

但是R最终崩溃了。这是我的会话信息
