I want to know how to store the values of the complete loop output into a single dataframe in R. For example,

for(i in unique(x$id)){
    .
    .
    .
    y=out

    You can do this simply by

    y  <- NULL;
    for (i in unique(x$id))
     { 
      tmp <- [output of one iteration]
      y <- rbind(y, tmp)
     }
