jiggle {plotrix} | R Documentation |
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.
