coarsen  R Documentation 
coarsen
can be used to obtain a factor from a vector, similar
to cut
, but with less technical and more "aesthetic"
labels of the factor levels.
coarsen(x,...) ## S3 method for class 'numeric' coarsen(x, n=5, pretty=TRUE, quantiles=!pretty, breaks=NULL, brackets=FALSE, sep=if(brackets)";"else if(quantiles) "" else "  ", left="[", right="]", range=FALSE, labels=NULL, ...)
x 
a vector, usually a numeric vector 
n 
number of categories of the resulting factor 
pretty 
a logical value, whether 
quantiles 
a logical value, whether 
breaks 
a vector of break points or 
brackets 
a logical value, whether the labels should include brackets. 
sep 
a character string, used as a separator between upper and lower boundaries in the labels.

a character string, to be used as the left bracket 
right 
a character string, to be used as the right bracket 
range 
a logical value, whether the minimum and maximum of

labels 
an optional character vector of labels.

further arguments, passed on to
