Calculate equally spaced values within a range.
Calculates a specified number of equally spaced values in a range
jiggle(n,range=c(-1,1))
n |
The number of values to calculate. |
range |
The range within which to fit the values. |
jiggle is an alternative to the jitter function. Instead of using runif to provide the values, it calls sample and then scales the resulting values to the range specified. This guarantees that the values will be evenly spaced.
A vector of n values within the range specified.
