In order to come up with colors (30:53) you just need to convert the "cyl" column as a factor since 4, 6 and 8 are three fixed values which are essentially factors. This can be done by running the code: mtcars$cyl

Thank you for such a nice tutorial! May I suggest to replace "as.character(cyl)" with "as.factor(cyl)"? Although as.character still works, number of cylinder should be defined as factors in the dataframe.

I have to make a box plot. In that i have to show ratio between two types of cells. But my output in graph should be as - if ratio is 1 out put shall be zero, if ratio is greater than 1 let us assume 10/5= 2/1 it shall show value in box plot +2 or if value is 5/10 =1/2 the value shall be displayed as -2. Can you please guide me how to do this. I found such type of boxplot in a paper. Thanks in advance

Hi I am straggling to write R codes for the following statement my data set is for the first two statement is epldata and for the last statement is eplsummary any idea on what should I write for the codes? Create a visualisation showing the distribution of market value by playing position that highlights which position has the highest median value. Create a visualisation showing the distribution of player ages, facetted by position category. Create a visualisation of the distribution of Wikipedia page views for each player that highlights which club has the highest median number of page views.

Thanks for the tutorial. Is there a reason you are using as.character() instead of as.factor() to convert continuous variables into discrete?
@mohammadshokoohi5412
@mohammadshokoohi5412 5 лет назад
good point!! No preference, both works. I think as.factor() would make more sense.

Hey, I get the same error. If you run the following line of code, though, it works. Maybe the version changes affected the xlab and ylab commands. ggplot(mtcars,aes(mpg))+geom_histogram(binwidth=5)+ggtitle("Distribucion de mpg")+labs(x="kilometraje", y="frecuencia")
