In the original post you mentioned that e only held the first row.
But with what you showed I would have expected e to hold the last number printed.
So it's still unclear what you wanted to do or you didn't explain in enough detail what you were doing.
Which is why I asked for a reproducible example which you have not provided.

Although the output was shown inside the loop but when i tried to call the variable outside the loop it only gave the first row, where as it should have 35 rows as it showed inside loop.The command which i used in the loop is
>>> e<-print(sum(abs(b-m[,i])))
