Changing the xlim of numeric value causing error ggplot R

Question

I have a grouped barplot produced using ggplot in R with the following code

ggplot(mTogether, aes(x = USuniquNegR, y = value, fill = variable)) +
geom_bar(stat =         


        

Answer 1

You need to remove the cbind from

together<-data.frame(cbind(USperReasons,USperReasonsNY,USuniquNegR))

because str(together) tells that all three columns are factors.

With

together <- data.frame(USperReasons, USperReasonsNY, USuniquNegR)

the plot looks reasonable to me (without having to use ylim or xlim).

So, the error was not within ggplot2 but in data preparation. Therefore, please, provide a full working example which can be copied, pasted and run when asking a question next time. Thank you.

Answer 2

The problem is that you are cbind()ing your column vectors together, which converts the numbers to characters. Fix that and the rest should fix itself.

together<-data.frame(USperReasons,USperReasonsNY,USuniquNegR)
