  • how are you sir
    i want (ggplot ) for clusters for example bar plots of clusters


  • Hi Joachim,
    Hope you are well.
    Your tutorials are very helpful for understanding R programming for people without any background of the same.
    I’m hardcore biologist and wish to do data analyses and statistical analyses using R. However, I’m having trouble in finding reference for arranging my data (data frame) for certain packages (e.g.: vegan, microbiome, phyloseq, etc.)
    Can you help with these?



    • Hey Shruti,

      I’m fine, and you? 🙂

      First of all, thanks a lot for the very kind words! Glad to hear that you like the Statistics Globe tutorials!

      Regarding your question: I’m not a biologist, so I have never worked with these packages. However, could you explain how your data should be modified? Maybe we can still find a solution.



      • Thank you so much for your reply.
        I deal with with environmental samples and I use molecular methods to draw certain inferences based on data that I get (metagenomic) and relating it to various environmental factors such temperature, pH, etc and sometimes intra-comparison within the samples. There are packages in R (Bioconductor actually) like the ones I mentioned which are widely used and a re known to help create and obtain different interpretations. And my major query is that for each of these packages, for R to read the file, the data has to be arranged in a particular way, so how do we know it or is there a way where changes in the script would make file readable


  • Thank you so much for your reply. I would surely try this and see if it works.


  • Yes, thank you. I hope to find a solution soon too ☺😇

    I just wanted to say thank you for all of your videos, they have been incredibly helpful throughout the project that I’m conducting at the moment. I only started learning R a couple of months ago but I feel like I’ve come a long way thanks to your videos. Whenever I face a problem, I type it into youtube and the first thing that turns up is a clear video by you explaining exactly how to do it! Really appreciate all the hard work you have put into statistics globe, it is the best R resource I’ve used!

    • Wow, thank you so much Lasith! This is a wonderful feedback, and I’m very happy to hear that my videos helped to improve your R programming skills!

      Good luck with your further learning progress! 🙂

    Hello team, I had one year of experience in TECHNICAL CONTENT WRITING (freelance) and TECHNICAL CONTENT REVIEWER (3 Months experience)
    Here’s my articles:

    I am interested to contribute my knowledge in your platform
    On Python,R, PHP etc

  • Hello Joachim,
    Hope you are doing well. I want to find out if you could do a video on Bayesian mixing models using R Statistics software. Thank you.

    Hey Joachim,
    I chanced about this website today, and I am really amazed how simply the tutorials are explained. They have helped me a lot in my project, I just want to say Thank you for your work.

    • Hey Maitreyee,

      Thank you very much for this wonderful feedback! It’s great to hear that my tutorials are helpful for your project! 🙂


  • Hello i have a r project but little struggling, can i have your help? It s for put two charts with a diffferent x-axis beginning in the same point in the xaxis (0)

  • Hi, I have a question about sensitivity analysis in R, i fitted multinomial logit model, we have equations like this:

    consider this equation for example,

    V1 = ASC1 +a1×Inc+b1×HS+c1×Cld+e1×Dri+ f1×Edu+ g1×Loc+h1×HD+m1×Rnt

    for example , V1 is the utility for having one car in the households, we have V0=0 as a base category to compare each category with this reference.

    we have also V2, V3, V4 for having 2,3,4 or more cars,

    we estimated a1,b1,c1, and so on by the multinomial logit model, now I want to test the change in household income; we want to test both a 25% decrease (reflecting a possible economic downturn) and a 25% increase; and see the effects on the predicted number of cars, I know I should use the equations resulting of the model and predict function in R , but i do not know how?

    Best Regards

    • Hey Samin,

      Unfortunately, I’m not an expert for sensitivity analysis. However, I have created a quick example on how to use the predict function, so hopefully this is helpful to you:

      data <- data.frame(y = rnorm(100), # Example data
                         x = rnorm(100))
      my_mod <- lm(y ~ x, data) # Estimate linear regression model
      data_new <- data.frame(x = rnorm(50)) # New data frame without y
      data_new_predictions <- predict(my_mod, data_new) # Predict y for new data frame
      data_new_predictions # Print predictions for y

      In addition, you may ask your question in the Statistics Globe Facebook group:


  • Hello,
    I have built a package in R (with the name MSB), but I forgot to run the dependencies of this package first. So, I need to remove this package and reinstall it again.
    When I write the CMD commands it gives the following error:

    Error: unexpected symbol in “R CMD”

    Can you please help me with this problem?

    • Hey Sarah,

      Usually, you should be able to simply use the install.packages function to re-install a package. Have you already tried that?

    hey sir im a statistics student a researcher and im doing a research on bringing an accuracy in classification in machine learning so i need some help in R can i contact you personally ?

  • Hi Joachim, not a request, not a question – but I just wanted to thank you and the team for the great work! I keep coming back to your website, since it has up-to-date, high-quality, reliable answers to just about any question I have regarding R. Keep up the amazing work!
