11 Vector
- Generate a vector of numbers
11.1 R 
| Function | Explanation | Example. |
|---|---|---|
: |
Generate a sequence of values | x = 1:5; y = 7:9 |
seq |
Generate a sequence of values with specified start, stop and step | z = seq(from = 2, to = 10, by = 2) |
c |
Concatenate vectors | x = 1:5; y = 7:9; z = c(x,y) |
rep |
Generate repetitive values | rep(1:5, times = 2); rep(1:3; each = 3) |
11.2 Python 
| Function | Explanation | Example. |
|---|---|---|
range |
Generate a sequence of values | x = range(1, 6); y = range(2, 10, 2) |
arange |
Generate a sequence of values with specified start, stop and step (import numpy as np) |
z = np.arange(2, 10, 2) |
concatenate |
Concatenate vectors (import numpy as np) |
x = range(1,6); y = range(2, 10, 2); z = np.concatenate((x,y)) |
concatenate or repeat
|
Generate repetitive values (import numpy as np) |
x = range(1, 5); w = numpy.concatenate((x, x, x)); z = np.repeat(x, 3, axis = 0) |
