How to modify the colors of bars in a ggplot2 barplot in the R programming language. More details: statisticsglobe.com/change-co...
R code of this video:
data ＜- data.frame(x = LETTERS[1:5], # Create example data
y = c(4, 2, 7, 3, 5))
install.packages("ggplot2") # Install ggplot2 package
library("ggplot2") # Load ggplot2 package
ggplot(data, aes(x, y)) + # ggplot2 barplot with single color
geom_bar(stat = "identity")
ggplot(data, aes(x, y, fill = x)) + # Using default colors
geom_bar(stat = "identity")
ggplot(data, aes(x, y, fill = x)) + # Manually specifying colors
geom_bar(stat = "identity") +
scale_fill_manual(values = c("A" = "#353436",
"B" = "#1b98e0",
"C" = "red",
"D" = "red",
"E" = "green"))

[@matthias.statisticsglobe]

Thanks for your great response and good to hear that the video helped you out! May you want to subscribe the channel to be better prepared next time ;)

Thank you for this video! This is exactly what I was looking for. My plot looks so much better 🥲

[@StatisticsGlobe]

Glad it was helpful Ruby, thanks for the comment!

Thank you so much. This video was very helpful. Can I just ask, how did you load up your dataset with the x and y column in R?, I tried it and it didn’t work for me.
I’m very new to R and I want to know as much as possible. Thanks.

Hi Ifeanyi, thanks a lot for the kind words, glad you like my tutorials! Regarding your question: You can create this data set by running the first lines of code, i.e.
data ＜- data.frame(x = LETTERS[1:5], # Create example data
y = c(4, 2, 7, 3, 5))
Afterwards, the new data set with x and y has been created. Regards, Joachim

Hi, How to specify a nonlinear colorbar with equal spaces using filled.contour function?

[@StatisticsGlobe]

Hey Maher, thanks for the interesting question! Unfortunately, I have no experience with the filled.contour function yet, but this might be an interesting topic for a future tutorial.

[@mahersahyoun2355]

@@StatisticsGlobe Thanks. I've been searching, but no luck finding an answer to that 🙂. It would be great if you can help soon.

[@ahmed007Jaber]

now if you provided in this function 3 colours and you have say 6 bars; is there a way to let are make different shades of the provided colours?

[@StatisticsGlobe]

I think the simplest way to do this is to specify six different colors using a hex color code picker (see here: htmlcolorcodes.com/color-picker/). This way, you can use slightly darker colors to create a shading effect. Regards, Joachim

[@ahmed007Jaber]

@@StatisticsGlobe thank u for the tip; I was thinking there might be a solution to use regardless of the number of colours, it would self generate if it needs more

[@StatisticsGlobe]

Maybe it could be useful to you to create your own range of colors using colorRampPalette? Have a look here for more details: statisticsglobe.com/create-color-range-between-two-colors-in-r
