R ggplot - Error stat_bin requires continuous x variable

Question

My table is data.combined with following structure:

\'data.frame\':   1309 obs. of  12 variables:
 $ Survived: Factor w/ 3 levels \"0\",\"1\",\"None\": 1 2 2         


        

Answer 1

I had the same issue but none of the above solutions worked. Then I noticed that the column of the data frame I wanted to use for the histogram wasn't numeric:

df$variable<- as.numeric(as.character(df$variable))
