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

extractTitle <- function(Name) {     
Name <- as.character(Name) 

  if (length(grep("Miss.", Name)) > 0) { 
    return ("Miss.")
  } else if (length(grep("Master.", Name)) > 0) { 
    return ("Master.") 
  } else if (length(grep("Mrs.", Name)) > 0) { 
    return ("Mrs.") 
  } else if (length(grep("Mr.", Name)) > 0) { 
    return ("Mr.") 
 } else { 
    return ("Other") 
  } 
}

titles <- NULL 

for (i in 1:nrow(data.combined)){
  titles <- c(titles, extractTitle(data.combined[i, "Name"]))
}

data.combined$title <- as.factor(titles)

ggplot(data.combined[1:892,], aes(x = title, fill = Survived))+
       geom_bar(width = 0.5) +
        facet_wrap("Pclass")+
         xlab("Pclass")+
         ylab("total count")+
         labs(fill = "Survived")
