# cbreaks

From scales v0.4.1
by Hadley Wickham

##### Compute breaks for continuous scale.

This function wraps up the components needed to go from a continuous range to a set of breaks and labels suitable for display on axes or legends.

##### Usage

`cbreaks(range, breaks = extended_breaks(), labels = scientific_format())`

##### Arguments

- range
- numeric vector of length 2 giving the range of the underlying data
- breaks
- either a vector of break values, or a break function that will make a vector of breaks when given the range of the data
- labels
- either a vector of labels (character vector or list of expression) or a format function that will make a vector of labels when called with a vector of breaks. Labels can only be specified manually if breaks are - it is extremely dangerous to supply labels if you don't know what the breaks will be.

##### Examples

`library(scales)`

```
cbreaks(c(0, 100))
cbreaks(c(0, 100), pretty_breaks(3))
cbreaks(c(0, 100), pretty_breaks(10))
cbreaks(c(1, 100), log_breaks())
cbreaks(c(1, 1e4), log_breaks())
cbreaks(c(0, 100), labels = math_format())
cbreaks(c(0, 1), labels = percent_format())
cbreaks(c(0, 1e6), labels = comma_format())
cbreaks(c(0, 1e6), labels = dollar_format())
cbreaks(c(0, 30), labels = dollar_format())
# You can also specify them manually:
cbreaks(c(0, 100), breaks = c(15, 20, 80))
cbreaks(c(0, 100), breaks = c(15, 20, 80), labels = c(1.5, 2.0, 8.0))
cbreaks(c(0, 100), breaks = c(15, 20, 80),
labels = expression(alpha, beta, gamma))
```
