Hi, I am new to R. I am trying to regroup data frame using multiple constrains. for example
data frame: data value class percent 15526 36 4.6875 15527 62 85.9375 15527 82 32.4564 15528 36 70.3125 15528 62 9.375 15528 82 74.6875 I need to regroup each class that have greater than or equal to 70 percent into new group. Similarly, I also need to regroup each class that have less than 70 percent into new group. I can do this by using following syntax for each class class36<- data[data$class==36&data$percent>70,] class36a<- data[data$class==36&data$percent<=70,] but I have 100 different classes. In order to do this for all 100 classes, I have write that syntax 100 times. There would be some way to do dynamically to regroup for 100 classes (may be using for loop) but I dont know. Can you please help in this. Output should be like data frame: class36 value class percent 15528 36 70.3125 data frame: class36a value class percent 15526 36 4.6875 data frame: class62 15527 62 85.9375 data frame: class62a 15528 62 9.375 data frame: class82 15528 82 74.6875 data frame: class82a 15527 82 32.4564 Thank you very much your help..
