r scale 0 1

scale a series between two points in R Does any know of an R function to perform range standardization on a vector? I’m looking to transform variables to a scale between 0 and 1, while retaining rank order and the relative size of separation between values.

The first value represents the replacement for the min value, the second is the substitute for the max value. So it is possible to reverse the order by giving range = c(1,0). Default is c(0,1). margin [integer(1)] 1 = rows, 2 = cols. Same is in apply Default is 1.

O scale (or O gauge) is a scale commonly used for toy trains and rail transport modelling. Originally introduced by German toy manufacturer Märklin around 1900, by the 1930s three-rail alternating current O gauge was the most common model railroad scale in the United States and remained so until the early 1960s.
