Hi guys I am getting this error while plotting a bar graph and I am not able to get rid of it, I have tried both qplot and ggplot but still the same error.
Following is my code
#Investigate data further to build a machine learning model
data_country = data %>%
summarise(conversion_rate = mean(converted))
qplot(country, conversion_rate, data = data_country,geom = "bar", stat ="identity", fill = country)
ggplot(data_country)+aes(x=country,y = conversion_rate)+geom_bar()
stat_count() must not be used with a y aesthetic
1 China 0.001331558
2 Germany 0.062428188
3 UK 0.052612025
4 US 0.037800687
First off, your code is a bit off.
aes() is an argument in
ggplot(), you don't use
aes(...) + layers
Second, from the help file
By default, geom_bar uses stat="count" which makes the height of the bar proportion to the number of cases in each group (or if the weight aethetic is supplied, the sum of the weights). If you want the heights of the bars to represent values in the data, use stat="identity" and map a variable to the y aesthetic.
You want the second case, where the height of the bar is equal to the
conversion_rate So what you want is...
data_country <- data.frame(country = c("China", "Germany", "UK", "US"), conversion_rate = c(0.001331558,0.062428188, 0.052612025, 0.037800687)) ggplot(data_country, aes(x=country,y = conversion_rate)) +geom_bar(stat = "identity")
