Greetings everybody,
I'm new with R and I'm trying to do some statistical analysis with R using my data.
It is a DNA microarray data with 69 samples(row) and 7070 (column) variables. I read the file using the command 'file.table' and it can be done with no error.However, when I tried running a summary of the data, the result was not what I had expected. Below is an extract of the result. And I knew that the command summary will give a summary of a data's descriptive statistics such as it's median,mean,etc.So, what i want is the statistics summary of each gene (in each column).

     V7065          V7066        V7067        V7068            V7069   
 20     :29   20       :69   117    : 2   39     : 6   20         :69  
 25     : 4   X16699_at: 1   134    : 2   42     : 4   L49218_f_at: 1  
 30     : 4                  142    : 2   44     : 4                   
 23     : 3                  170    : 2   46     : 4                   
 26     : 3                  203    : 2   38     : 3                   
 21     : 2                  96     : 2   58     : 3                   

(Other):25 (Other):58 (Other):46
V7070 V7071 30 : 5 20 :69 21 : 4 Z78285_f_at: 1 51 : 4 64 : 4 27 : 3 36 : 3

(Other):47

My data is in .dat format. Also, I have downloaded a few .rda files to be tried out with R but how do I view them as data per se, like the .dat file can be viewed and edited using Notepad, how about the .rda files? I express my greatest appreciation all who help. Thank you.
