[R] Need R code

[bogdan romocea]

Here's an example.

lst <- list()
for (i in 1:5) {
   lst[[i]] <- data.frame(v=sample(1:20,10),sample(1:5,10,replace=TRUE))
   colnames(lst[[i]])[2] <- paste("x",i,sep="")
   }
dfr <- lst[[1]]
for (i in 2:length(lst)) dfr <- merge(dfr,lst[[i]],all=TRUE)
dfr <- dfr[order(dfr[,1]),]
print(dfr)
