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
