Vector of Prettied Values

DESCRIPTION:

Returns a vector of ordered and equally spaced (pretty) values that span the range of the input.

USAGE:

pretty(x, nint = 5) 

REQUIRED ARGUMENTS:

x
vector of data; prettied values will cover the range of x. Missing values ( NAs) are allowed.

OPTIONAL ARGUMENTS:

nint
approximate number of intervals desired.

VALUE:

vector of approximately nint values that are ordered and equally spaced numerically over the range of the input x. The individual values will differ by 1, 2 or 5 times a power of 10.

EXAMPLES:

mydata <- 1:10 
pretty(mydata, 10) 
pretty(0:1) # returns c(0, .2, .4, .6, .8, 1) 
pretty(0:1, 2) # returns c(0, .5, 1) 
pretty(0:1, 1) # returns c(0, 1) 
pretty(c(.1, .98), 3) # returns c(0, .2, .4, .6, .8, 1) 
pretty(c(.1, 1.05), 3) # returns c(0, .5, 1, 1.5)
