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?

Regards,

Shruti

  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.
  
  Regards
  
  Joachim

    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

      The required data format depends on the functions and packages you are using. First, I would have a look at the help documentation of the function you want to use (i.e. write a ? in front of the function name and execute it in the RStudio console). This should give you an idea on how to format your data.
      
      Once you know the required format, you can use the search function on Statistics Globe. I have created many tutorials on data manipulation already. Some tutorials that might be useful to manipulate your data:
      
      https://statisticsglobe.com/reshape-data-frame-from-wide-to-long-format-in-r
      https://statisticsglobe.com/r-order-data-frame-rows-according-to-vector
      https://statisticsglobe.com/add-column-to-data-frame-in-r
      
      If you don’t find a solution, you may post your question to the Statistics Globe Facebook group. In this group, people can ask questions about R programming and statistics. By posting there, others can contribute as well: https://www.facebook.com/groups/statisticsglobe
      
      I hope that helps!

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!

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

Joachim

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: https://www.facebook.com/groups/statisticsglobe

Regards,
Joachim
