For loop in R with increments

Question

I am trying to write a for loop which will increment its value by 2. The equivalent code is c is ``` for (i=0; i<=78; i=i+2) ``` How do I achieve the same in R?

Accepted Answer

See `?seq` for more info:

```
for(i in seq(from=1, to=78, by=2)){
#  stuff, such as
  print(i)
}
```

or

```
for(i in seq(1, 78, 2))
```

p.s. Pardon my C ignorance. There, I just outed myself.

However, this is a way to do what you want in R (please see updated code)

EDIT

After learning a bit of how C works, it looks like the example posted in the question iterates over the following sequence: `0 2 4 6 8 ... 74 76 78`.

To replicate that exactly in R, start at `0` instead of at `1`, as above.

```
seq(from=0, to=78, by=2)
 [1]  0  2  4  6  8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44
[24] 46 48 50 52 54 56 58 60 62 64 66 68 70 72 74 76 78
```
