I'm using megacc (MEGA's version for DEBIAN) to produce pairwise difference matrices. Now, I want to load the matrices into R for further analysis. MEGA's format looks like this

#mega
 !Title: ;
 !Format DataType=Distance DataFormat=LowerLeft NTaxa=16;
 !Description
 No. of Taxa : 16
 ... More INFO ...
 ;

 [ 1] #Outgroup
 [ 2] #Seq
 ... More IDs ...

 [   1      2       3      4      5 ....

 [ 1]                
 [ 2]  1245.00000000               
 [ 3]  1180.00000000 1146.00000000               
 [ 4]  1185.00000000 1149.00000000   59.00000000               
 [ 5]  1188.00000000 1154.00000000   58.00000000   43.00000000

Is there a way to safely upload this output file into R? Or even better, produce MEGA output that is already R compatible? Bear in mind that I'm using the command line version of MEGA and not the GUI, which easily allows to export data in csv format.
