ggplot2: Weighted scatterplot between groups

I am trying to create a weighted scatterplot between three groups.

Example:

library(ggplot2)
df <- data.frame("groups" = c('AA','BB','CC', 'AA','BB','CC', 'AA','BB','CC'), 
               "something" = c('aaaaaa', 'bbbbb', 'cccccc', 'dddddddd', 'eeeeeee', 'ffffffff', 'gggggggggg', 'hhhhhhhhh', 'iiiiiiiii'),
               "value1" = c(1.1, 2.4, 3.5, 5, 4.1, 3, 2.5, 1.4, 4.5),
               "value2" = c(2, 25, 10, 4, 15, 5, 3, 4, 8))

I have tried the below code to plot the weighted scatterplot and get output similar to Scatter.14 from here.

ggplot(data = df, aes(x = groups, y = something, size = value1, color = -log10(value2)))+
geom_point()+
scale_color_gradientn(colors = rainbow(4))+
theme_bw()+
theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank())

I keep getting the error when I run the above code.

Error in farver::decode_colour(colors, alpha = TRUE, to = "lab", na_value = "transparent") : 
unused argument (na_value = "transparent")

The sessionInfo() is like this:

Is there any way to fix this error? Or if there is a better approach?

Try updating your farver package. You have version 2.0.1. I have 2.0.3, and I cannot replicate your error.
