r - 加载一个大的 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
