#################################################
# APPEND ROWS ITERATIVELY TO A DATA FRAME #
#################################################
# LOOP FROM 1 TO 10
for(i in 1:10)
{
# SET THE RANDOM STATE
set.seed(i);
# CREATE A DUMMY DATA FRAME ITERATIVELY
data<-data.frame(iter = i, x = rnorm(1), y = runif(1));
# ASSIGN THE ROW NAME
row.names(data)<-i;
# APPEND NEW DATA TO THE END OF MAIN DATA FRAME
if (i == 1) main<-data else main<-rbind(main, data);
};
