Boa tarde, Estou montando um padrão de pre-tratamento de dados, a princípio montei para uma matrix de 39 linhas e 31 colunas, porém gostaria de fazer de uma forma que funcione para qualquer tamanho de matrix. Segue o que fiz (Em negrito estão as informações que necessito calcular) M1<-matrix(min(B1[,1]),39,1);M2<-matrix(min(B1[,2]),39,1);M3<-matrix(min(B1[,3]),39,1);M4<-matrix(min(B1[,4]),39,1);M5<-matrix(min(B1[,5]),39,1);M6<-matrix(min(B1[,6]),39,1);M7<-matrix(min(B1[,7]),39,1);M8<-matrix(min(B1[,8]),39,1);M9<-matrix(min(B1[,9]),39,1);M10<-matrix(min(B1[,10]),39,1);M11<-matrix(min(B1[,11]),39,1);M12<-matrix(min(B1[,12]),39,1);M13<-matrix(min(B1[,13]),39,1);M14<-matrix(min(B1[,14]),39,1);M15<-matrix(min(B1[,15]),39,1);M16<-matrix(min(B1[,16]),39,1);M17<-matrix(min(B1[,17]),39,1);M18<-matrix(min(B1[,18]),39,1);M19<-matrix(min(B1[,19]),39,1);M20<-matrix(min(B1[,20]),39,1);M21<-matrix(min(B1[,21]),39,1);M22<-matrix(min(B1[,22]),39,1);M23<-matrix(min(B1[,23]),39,1);M24<-matrix(min(B1[,24]),39,1);M25<-matrix(min(B1[,25]),39,1);M26<-matrix(min(B1[,26]),39,1);M27<-matrix(min(B1[,27]),39,1);M28<-matrix(min(B1[,28]),39,1);M29<-matrix(min(B1[,29]),39,1);M30<-matrix(min(B1[,30]),39,1);M31<-matrix(min(B1[,31]),39,1);Mmin<-cbind(M1,M2,M3,M4,M5,M6,M7,M8,M9,M10,M11,M12,M13,M14,M15,M16,M17,M18,M19,M20,M21,M22,M23,M24,M25,M26,M27,M28,M29,M30,M31);M1<-matrix(max(B1[,1]),39,1);M2<-matrix(max(B1[,2]),39,1);M3<-matrix(max(B1[,3]),39,1);M4<-matrix(max(B1[,4]),39,1);M5<-matrix(max(B1[,5]),39,1);M6<-matrix(max(B1[,6]),39,1);M7<-matrix(max(B1[,7]),39,1);M8<-matrix(max(B1[,8]),39,1);M9<-matrix(max(B1[,9]),39,1);M10<-matrix(max(B1[,10]),39,1);M11<-matrix(max(B1[,11]),39,1);M12<-matrix(max(B1[,12]),39,1);M13<-matrix(max(B1[,13]),39,1);M14<-matrix(max(B1[,14]),39,1);M15<-matrix(max(B1[,15]),39,1);M16<-matrix(max(B1[,16]),39,1);M17<-matrix(max(B1[,17]),39,1);M18<-matrix(max(B1[,18]),39,1);M19<-matrix(max(B1[,19]),39,1);M20<-matrix(max(B1[,20]),39,1);M21<-matrix(max(B1[,21]),39,1);M22<-matrix(max(B1[,22]),39,1);M23<-matrix(max(B1[,23]),39,1);M24<-matrix(max(B1[,24]),39,1);M25<-matrix(max(B1[,25]),39,1);M26<-matrix(max(B1[,26]),39,1);M27<-matrix(max(B1[,27]),39,1);M28<-matrix(max(B1[,28]),39,1);M29<-matrix(max(B1[,29]),39,1);M30<-matrix(max(B1[,30]),39,1);M31<-matrix(max(B1[,31]),39,1);Mmax<-cbind(M1,M2,M3,M4,M5,M6,M7,M8,M9,M10,M11,M12,M13,M14,M15,M16,M17,M18,M19,M20,M21,M22,M23,M24,M25,M26,M27,M28,M29,M30,M31);M1<-matrix(mean(B1[,1]),39,1);M2<-matrix(mean(B1[,2]),39,1);M3<-matrix(mean(B1[,3]),39,1);M4<-matrix(mean(B1[,4]),39,1);M5<-matrix(mean(B1[,5]),39,1);M6<-matrix(mean(B1[,6]),39,1);M7<-matrix(mean(B1[,7]),39,1);M8<-matrix(mean(B1[,8]),39,1);M9<-matrix(mean(B1[,9]),39,1);M10<-matrix(mean(B1[,10]),39,1);M11<-matrix(mean(B1[,11]),39,1);M12<-matrix(mean(B1[,12]),39,1);M13<-matrix(mean(B1[,13]),39,1);M14<-matrix(mean(B1[,14]),39,1);M15<-matrix(mean(B1[,15]),39,1);M16<-matrix(mean(B1[,16]),39,1);M17<-matrix(mean(B1[,17]),39,1);M18<-matrix(mean(B1[,18]),39,1);M19<-matrix(mean(B1[,19]),39,1);M20<-matrix(mean(B1[,20]),39,1);M21<-matrix(mean(B1[,21]),39,1);M22<-matrix(mean(B1[,22]),39,1);M23<-matrix(mean(B1[,23]),39,1);M24<-matrix(mean(B1[,24]),39,1);M25<-matrix(mean(B1[,25]),39,1);M26<-matrix(mean(B1[,26]),39,1);M27<-matrix(mean(B1[,27]),39,1);M28<-matrix(mean(B1[,28]),39,1);M29<-matrix(mean(B1[,29]),39,1);M30<-matrix(mean(B1[,30]),39,1);M31<-matrix(mean(B1[,31]),39,1);Mmean<-cbind(M1,M2,M3,M4,M5,M6,M7,M8,M9,M10,M11,M12,M13,M14,M15,M16,M17,M18,M19,M20,M21,M22,M23,M24,M25,M26,M27,M28,M29,M30,M31); M1<-matrix(var(B1[,1]),39,1);M2<-matrix(var(B1[,2]),39,1);M3<-matrix(var(B1[,3]),39,1);M4<-matrix(var(B1[,4]),39,1);M5<-matrix(var(B1[,5]),39,1);M6<-matrix(var(B1[,6]),39,1);M7<-matrix(var(B1[,7]),39,1);M8<-matrix(var(B1[,8]),39,1);M9<-matrix(var(B1[,9]),39,1);M10<-matrix(var(B1[,10]),39,1);M11<-matrix(var(B1[,11]),39,1);M12<-matrix(var(B1[,12]),39,1);M13<-matrix(var(B1[,13]),39,1);M14<-matrix(var(B1[,14]),39,1);M15<-matrix(var(B1[,15]),39,1);M16<-matrix(var(B1[,16]),39,1);M17<-matrix(var(B1[,17]),39,1);M18<-matrix(var(B1[,18]),39,1);M19<-matrix(var(B1[,19]),39,1);M20<-matrix(var(B1[,20]),39,1);M21<-matrix(var(B1[,21]),39,1);M22<-matrix(var(B1[,22]),39,1);M23<-matrix(var(B1[,23]),39,1);M24<-matrix(var(B1[,24]),39,1);M25<-matrix(var(B1[,25]),39,1);M26<-matrix(var(B1[,26]),39,1);M27<-matrix(var(B1[,27]),39,1);M28<-matrix(var(B1[,28]),39,1);M29<-matrix(var(B1[,29]),39,1);M30<-matrix(var(B1[,30]),39,1);M31<-matrix(var(B1[,31]),39,1);Mvar<-cbind(M1,M2,M3,M4,M5,M6,M7,M8,M9,M10,M11,M12,M13,M14,M15,M16,M17,M18,M19,M20,M21,M22,M23,M24,M25,M26,M27,M28,M29,M30,M31) N1<-(B1-Mmin)/(Mmax-Mmin);N2<-(B1-Mmean)/(Mmax-Mmean);N3<-(B1-Mmean)/(Mmax-Mmin);N4<-(B1-Mmean)/Mvar;N5<-sqrt(B1);N6<-log(B1);N7<-log(B1,10);N8<-1/sqrt(B1);N9<-1/B1;N10<-log((B1-Mmin)/(Mmax-B1)); Agradeço antecipadamente qualquer tipo de auxílio.
