[R] How to extract information from .Rdata format

[Ana Marija]

do you think that this is useful output from Basics of R?
> load("paired_example.Rdata")
> str(rawdata)
 num [1:4482, 1:10] 46 4 3 48 1 4 0 60 0 12 ...
 - attr(*, "dimnames")=List of 2
  ..$ : chr [1:4482] "gene1" "gene2" "gene3" "gene4" ...
  ..$ : chr [1:10] "a.cancer" "b.cancer" "c.cancer" "d.cancer" ..

I think this one is better:
> dat<-local(get(load("paired_example.Rdata")))
> head(dat)
      a.cancer b.cancer c.cancer d.cancer e.cancer a.normal b.normal c.normal
gene1       46        4       33        5        8       61        5       42
gene2        4        0        2        1        5       24        1       30
gene3        3        4        4        2        1        3        0        0
gene4       48        2       10        0        6        9        4        3
gene5        1        5        2        3        6        1        0        3
gene6        4        0        0        1        1        4        0        7
