Eliminating NAs from a ggplot

Question

Very basic question here as I\'m just starting to use R, but I\'m trying to create a bar plot of factor counts in ggplot2 and when plotting, get 14 little colored blips repr

Answer 1

You can use the function subset inside ggplot2. Try this

library(ggplot2)

data("iris")
iris$Sepal.Length[5:10] <- NA # create some NAs for this example

ggplot(data=subset(iris, !is.na(Sepal.Length)), aes(x=Sepal.Length)) + 
geom_bar(stat="bin")
