请教R语言.Rdata的问题

tempo8

文章作者发给我一个.Rdata包，作者提示：
By loading this object in an R session (using the load command) and having the "Matrix" package installed which you most probably have【我确实安装了】, you will get a variable named
M:
M$PPI is the protein-protein interaction matrix (sparse binary matrix)
M$COEX is the co-expression matrix
M$S: is the Interpro signature matrix
M$L: is the GO annotation matrix

于是我在R2.15中用
> load("D:\\My Documents\\2012.Rdata")
请问接下来怎么看运行的数据？谢谢

tempo8

ls()显示[1] "M"
>M$PPI
运行后得到一个矩阵matrix,
可是如何输出这个矩阵的数据呢？谢谢

回复 2# tempo8

write.table(M$PPI,"example.txt")

具体可以参考

help(write.table)
