Backtransform Log scale

[Adrián Naveda-Rodríguez]

Hi,
I am making a regression model plot where the response variable is log
transformed. I want to plot the prediction using the original scale. I have
tried using scales_y_continuous() but it did not work.
Does any body knows how to backtransform log scale in ggplot?

Thanks, Adrian

Unbelievable, i was looking at this an hour ago. I will submit to anyone providing a better solution than this, but in a hurry. But, log2(x) can be transformed back by (2**x)

library(ggplot2)

data=mtcars
data$LogMPG <- log2(data$mpg)
ggplot(data, aes(x=wt, y=(2**LogMPG))) + geom_point()

# or
data$NewMpgFromLog <- 2**(data$LogMPG)
