%of% {ggallin}

Composition of scale transforms.

Description

A binary infix operator that allows one to compose together two scale transformations. We should have that the transformation atrans %of% btrans first applies btrans, then applies atrans to the results. This is useful for reversing scales, for example, along with other transformations.

Usage

atrans %of% btrans

Arguments

atrans

a transformation object.

btrans

a transformation object.

Value

a transformation object that perfroms atrans on the output of btrans.

# compose transformatins with %of%:
ggplot(data.frame(x=rnorm(100),y=exp(rnorm(100,mean=-2,sd=4))),aes(x=x,y=y)) + 
  geom_point() + 
  scale_y_continuous(trans=scales::reverse_trans() %of% scales::log10_trans())
