Re: [R] Best and worst values for each date

Ira, You may try also with ?ddply() dat2<- data.frame(S1=rep(Pred1[,1],ncol(Pred1)-1),variable=rep(colnames(Pred1)[-1],each=nrow(Pred1)),Predict=unlist(Pred1[,-1],use.names=FALSE),Actual=unlist(Actual1[,-1],use.names=FALSE),stringsAsFactors=FALSE)  identical(dat,dat2) #[1] TRUE dat2New<- dat2[!(

Re: [R] Best and worst values for each date

Hi, May be you can try this: obj_name<- load("arun.RData") Pred1<- get(obj_name[1]) Actual1<- get(obj_name[2]) library(reshape2) dat<-cbind(melt(Pred1,id.vars="S1"),value2=melt(Actual1,id.vars="S1")[,3])  # to reshape to long form colnames(dat)[3:4]<- c("Predict","Actual") dat$variable<- as.cha
