Rescale Data to Lie Between Specified Limits
Rescales a dataset so that the values range exactly between the specified limits.
Usage
scaletointerval(x, from=0, to=1)
## S3 method for class 'default':
scaletointerval(x, from=0, to=1)
## S3 method for class 'im':
scaletointerval(x, from=0, to=1)
Arguments
- x
- Data to be rescaled.
- from,to
- Lower and upper endpoints of the interval
to which the values of
x
should be rescaled.
Details
These functions rescale a dataset x
so that its values range exactly between the limits
from
and to
.
The method for pixel images (objects of class "im"
)
applies this scaling to the pixel values of x
.
Rescaling cannot be performed if the values in x
are not
interpretable as numeric, or if the values in x
are all equal.
Value
- An object of the same type as
x
.
