R help - Apr 2013 - call a variable from outside of for loop

Dear useRs,
While using print command in "for" loop, i designated a variable being
printed by "e". 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])))

Kindly help me on it..

Give us a reproducible example of what you are trying to do.
This doesn't make sense.

Hello,

It seems that you're recreating the variable 'e' every time through
the
loop. In the end you only have 1 row. Try to create it outside the loop, 
like

e <- vector("list", 35)

Then inside the loop

e[[i]] <- print(...)

Hope this helps,

Rui Barradas
