Rescale continuous vector to have specified minimum and maximum

rescale(x, to, from, ...)

# S3 method for numeric
rescale(x, to = c(0, 1), from = range(x, na.rm = TRUE, finite = TRUE), ...)

# S3 method for dist
rescale(x, to = c(0, 1), from = range(x, na.rm = TRUE, finite = TRUE), ...)

# S3 method for logical
rescale(x, to = c(0, 1), from = range(x, na.rm = TRUE, finite = TRUE), ...)

# S3 method for POSIXt
rescale(x, to = c(0, 1), from = range(x, na.rm = TRUE, finite = TRUE), ...)

# S3 method for Date
rescale(x, to = c(0, 1), from = range(x, na.rm = TRUE, finite = TRUE), ...)

# S3 method for integer64
rescale(x, to = c(0, 1), from = range(x, na.rm = TRUE), ...)

Arguments

x	continuous vector of values to manipulate.
to	output range (numeric vector of length two)
from	input range (vector of length two). If not given, is calculated from the range of `x`
...	other arguments passed on to methods
