data not recognized as data.frame

[jotasolano]

Hello. Sorry to bother you. I'm having issues implementing the library. I tried the example from the documentation but I get the error:

Error in alpha(data$fill, data$alpha) :
Data must either be a data frame or a matrix

Thanks for putting this library out there, I would really like to use it. This is my script:

library(ggplot2)
library(ggmosaic)
library(NHANES)

df.1 <- data.frame(NHANES, stringsAsFactors = F)

ggplot(data = df.1) +
  geom_mosaic(aes(weight = Weight, x = product(SleepHrsNight), fill=factor(SleepHrsNight)), na.rm=TRUE) +
  labs(x="Hours of sleep a night ", title='f(SleepHrsNight)') + guides(fill=guide_legend(title = "SleepHrsNight", reverse = TRUE))

What am I missing?

@jotasolano could you add your session info? - it seems we have overlooked a dependency, and updating to a newer version of (some of) the package(s) we depend on would solve the issue.
Based on this particular error message looks like it might be the scales package.

@heike I re-installed scales and it did it!. Thank you so much for your quick reply. I'll attach the session regardless in case someone else runs with the same issue.
