I'm trying to massage some data from Matlab into R. The matlab file
has a "struct array" which when imported into R using the R.matlab
package, becomes an R list with 3+ dimensions, the first of which
corresponds to the structure fields, with corresponding row names, and
the second and third+ dimensions correspond to the dimensions of the
original struct array (as matlab arrays always have 2+ dimensions).
For example a 1x1 matlab struct array with three fields becomes:
> data
, , 1
[,1]
trials List,1002
beforeRun List,8
afterRun List,8
If I load two data files, I would want to concatenate them into a
single list. cbind() doesn't preserve the row names, possibly because
the array has three dimensions?
> cbind(data1, data2)
data1 data2
[1,] List,1002 List,479
[2,] List,8 List,8
[3,] List,8 List,8
Then I looked into abind(), which is even more puzzling: it preserves
the names and dimensions correctly, but converts the entries into
strings?!
> abind(list(data1, data2), along=2, force.array=FALSE)
, , 1
[,1] [,2]
trials "0" "1"
beforeRun "2079647.50207592" "0"
afterRun "1" "0"
Is there a quick way to accomplish the effect I want? I want an output
that looks like:
> somebind(data1, data2, along=2)
, , 1
[,1] [,2]
trials List,1002 List,479
beforeRun List,8 List,8
afterRun List,8 List,8
Cheers,
Peter
