[R] "ciclo for" in matrix construction ( matlab -> R )

 hi, i'm new to R i have a little script in matlab.... now i'm porting it to R but i've some problem. how can i write in R language this matlab/octave code: LX = L ;                     >>> L is a matrix ss = size(LX,1); E_N_2 = zeros(ss,2); for i = 1:ss E_2 = E_0 + LX(i,1)*C(3)+LX(i,2)*C(4);      >>>> E_0 , C(3), c(4)   are costant N_2 = N_0 + LX(i,2)*C(3)-LX(i,1)*C(4); r=[ E_2,N_2]; E_N_2(i,:)=r; end E_N_2 i'm try so : library(matlab) LX <- L ss <- dim(LX) ss <- ss[1] E_N_2 <- zeros(ss,2) for(i in 1:ss) ..... .....? thanks for any help :-) Massimo my mayor problem is to know how the "cicle for" works         [[alternative HTML version deleted]] ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.
