Hi All,
I have a data frame like this:
> head(b)
LRET02 LRET04 LRET06 LRET08 LRET10 LRET12 LRET14
1 0 0.6931472 . 1.0986123 1.0986123 1.0986123 0.6931472
2 2.1972246 2.4849066 2.4849066 . 2.5649494 2.6390573 2.6390573
3 1.6094379 1.7917595 1.6094379 1.7917595 2.0794415 1.9459101 2.0794415
4 0 0 0 0 0 0 0
5 0.6931472 0 1.0986123 1.0986123 0.6931472 0.6931472 0.6931472
6 1.0986123 1.0986123 1.0986123 0.6931472 1.0986123 1.3862944 1.0986123
All values in this data frame are product of natural log. I have to do
inverse of it.
So for example do do inverse of 0.6931472 I would do:
> 2.718281828^0.6931472
[1] 2
How do I perform this operation for every single value in this data frame?
The original data frame is this dimension:
> dim(b)
[1] 1441 18
Thanks
Ana
