Color error in ggplot2 (Error in grDevices::col2rgb(colour, TRUE) : invalid RGB specification)
Sorry I am late, but the problem is that the function alpha is masked form ggplot2, that's why if you restart R and happen to call alpha after sourcing psych but before ggplot2 it works.
Anyway, the way to solve it is to make explicit that we want the psych function:
reliability = psych::alpha(df)

If I run:
library(ggplot2) ToothGrowth$dose <- as.factor(ToothGrowth$dose) bp<-ggplot(ToothGrowth, aes(x=dose, y=len, fill=dose)) + geom_boxplot() bp
I see the error: Error in grDevices::col2rgb(colour, TRUE) : invalid RGB specification.
If I run the identical code on my other computer, I get the expected plot. I am guessing that some plotting parameter is the culprit, but I have no idea how to find it. What's going wrong?
The computer that behaves strangely is Mac OS X 10_11_3 running R 3.2.2 via RStudio 0.99.489
