I'm starting out in R and would need a little help! I am trying to make a bar graph with the average of factors.
I have 2 columns:
Col1 with qualitative values to factor : red, black, blue
Col2 with quantitative values so I want to get the average
Here is what I could initiate, but I get the global average...
BDD$Col1 <- as.factor(BDD$Col1)
moy <- mean(BDD$Col2, na.rm = TRUE)
color_table <- data.frame(color = BDD$Col1, mean = moy)
ggplot(BDD, aes(x = Col1, fill = moy)) +
ylab("Average by color")
With the desired result:
(aggregated) Associated mean
Thank you very much for your help!
