Welcome to CloudStat. Today tutorial is about sequence function, seq().
To output from 1 to 10, commonly we will use
And, we can use sequence function, seq()
In this case, we type seq(from=1, to=10, by=1)
We can observe that
# a:b is same as seq(from=a,to=b,by=1) or seq(a,b,1)
What if we wanted only the odd numbers?
We can use c(1,3,5,7,9) or yes we can use seq() funtion, seq(1,10,2)
Sequence function is very useful when we want to output many numbers with different pola.
For example seq(-100,100,10)
We're outputing from -100 to 100 by 10.
Next, we want to find equal points.
We want to find 10 equal points from 1 to 10.
We use seq(1,10,len=10)
To see the different, we type one more,
This command is getting 4 equal points instead of ten from 1 to 10.
Hope you enjoy this tutorial. Have a nice day.
