Rescale vector to have specified minimum, midpoint, and maximum

rescale_mid(x, to, from, mid, ...)

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

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

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

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

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

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

Arguments

x	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`
mid	mid-point of input range
...	other arguments passed on to methods
