Subject: equating approximate values
Hello List,
I am having trouble finding the command for my problem.
I have two arrays x and y. now i would like to compare the values of x and y
and then get the index of x which is exactly or approximately equal(+/- some
value ) to the values in y.
x <- runif(100,min=0,max=5)
y <- runif(10,min=0,max=5)
the threshold value(+/-) value can vary. for this example lets take it to be
.5
I know the regular method of doing this by writing different if and for
loops. But i have very big dataframe the computation time is very high for
this method. can anyone please tell me if there any functions to do this.
thank you for your help.
