I keep entering the following statement and it states "x" must be numeric and I have no clue why!

hist(cars,ylab = "Frecuencia por paises",xlab = "Automoviles por mil habitantes",main = "Histograma de automoviles por cada 1000 habitates",ylim = c(0,10),col = ("magenta"))

  • `x` clearly isn't numeric. [Please show your dataset](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) the way we can make at least an educated guess. A reproducible example would be the ultimate goal, though. – Roman Luštrik Mar 03 '17 at 11:53

define your dataset (say as df)

#to convert cars column into numeric format
df$cars<-as.numeric(as.character(df$cars))

hist(df$cars,....)

... other arguements

Also u can try ggplot for better visualization

library(ggplot2)
ggplot(df, aes(Country,Cars))+geom_bar(stat="identity")
