List of multidimensional arrays

Dear Berend,

I am not familiar at all with ascii text. If you could suggest me a good link to learn about it, then it would be really helpful!

Best wishes,
Loukia

You were asked to provide R code in ascii text.
Also use dput to get the objects into a mail.

Nobody is going to make the effort to copy from your pdf. I certainly will not.

x and y are the frequencies of missing participants in the intervention and
the control treatment respectively! vector t contains the code of the
interventions (we have 11 interventions). I re-attach the PDF with some
small modifications. I am trying to create a list, where each list element
is a vector of different length arrays that contain 2by2 matrices. To be
more specific there are 11 treatments that are compared with placebo (we
have 11 comparisons) and each comparison is studied by a different number
of trials and each trial has a different number of missing participants in
both arms. The length of the list is equal to the number of comparisons. In
each comparison the number of arrays is equal to the number of trials that
study this comparison. For instance 4 trials compare PAR with placebo. So,
for this comparison we have 4 arrays and each array has a length equal to
the producy of the number of participants in each arm. These arrays contain
2x2 matrices.

I have attached a document with the data and the code. I cannot create the
list results the way I have described above. It creates only the  matrices
for the first array (that has length equal to 135) of the first comparison
leaving the rest 10 comparisons "NULL".

I am looking at your pdf file.

it doesn't match your description.

There are no missing values in the vectors
x, y, t.
Each vector has length 55 which is not a multiple of 4,
so we don't know where the 2x2 matrices come from.

The code doesn't run.  There are are too many "}".
PDF files are formatted and are not ascii.

Please send your code in ascii text in the body of the email.
Please pick it up from your email and paste it into
a fresh R session to be sure that it works.

Perhaps consrtruct manually an example of what you want the answer to look
like.
