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.

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.

Loukia,
Please send your replies to the Rhelp list. I am CC'ing this to the Rhelp list. On 25102012, at 15:30, Loukia Spineli wrote: > 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! If that is so, then how are you making your R code or R script? You must be using a plain text editor but we don't know your version of R, your OS, or anything else. If you are only using an R console you should look in the documentation of your system to find out how to work with plain text.

hello,
I want to make a two dimensional matrix from the data table.That data table has three column 1st is userid,2nditemid and 3rd is rating corresponding to the itemid given by userid.I want to make a m*n matrix in which 'm' is userid and 'n' to be itemid .That 2D matrix should b filled with that corresponding rating for that itemid for that userid. please help me out. 
You are very lucky. This question was answered last week in
https://stat.ethz.ch/pipermail/rhelp/2012October/326597.html For the future, please read the posting guide referenced below and include an example of your data and the result of the calculation you would like to see. Please use Rhelp directly and not the nabble interface.
