Convert log2 fold change to signed fold change
log2fold_to_fold(x, ...)
x |
|
This function takes log2 fold change values as input, and returns normal space fold change values that retain the positive and negative sign, and the magnitude.
For example:
log2 fold change = 2
becomes fold change = 4
.
log2 fold change = -2
becomes fold change = -4
.
This function therefore differs from similar functions that convert
log2 fold change into a ratio. Instead, log2fold_to_fold()
specifically retains the magnitude of negative changes.
numeric
