Convert normal signed fold change to log2 fold change
fold_to_log2fold(x, ...)
x |
|
This function takes fold change values as input, and returns log2 fold change values.
This function recognizes two forms of input:
ratio, which includes values between 0 and 1, but no negative values;
fold change, as from log2fold_to_fold()
which includes no values
between 0 and 1, but may include negative values.
For example, for ratio input:
ratio = 4
becomes log2 fold change = 2
.
ratio = 0.25
becomes log2 fold change = -2
.
For example, for fold change input:
fold change = 4
becomes log2 fold change = 2
.
fold change = -4
becomes log2 fold change = -2
.
numeric
