Adjuts number of digits for small pvalue to be displayed in title of a plot using renderPlot in Shiny in R

In R one can use options(digits=n) to adjust the number of digits in the output value. However, this does not work in Shiny, and sprintf() does not work with very low numbers either since it would only display zeros. So, how could i obtain in Shiny something like options(digits = 4) p.val$p.value [1] 3.724e-23 So… Read More Adjuts number of digits for small pvalue to be displayed in title of a plot using renderPlot in Shiny in R

How to extract lower and upper bounds from confidence level in R from t test function?

I used the following code to retrieve a confidence level for my data: c <- t.test(my_data$my_col, conf.level = 0.95) c This returns something like: data: my_data$my_column t = 30, df = 20, p-value < 2.1e-14 alternative hypothesis: true mean is not equal to 0 95 percent confidence interval: 62.23191 80.11201 sample estimates: mean of x… Read More How to extract lower and upper bounds from confidence level in R from t test function?

ggplot2 dual axes plot with character vector on secondary axis

I want to include a secondary y-axis in my coefficient plot. On the secondary axis, I want to display a var which contains the point estimates and their 95% CI. The examples I have seen so far work if the information on the secondary axis is numeric but my var is character. For example, in… Read More ggplot2 dual axes plot with character vector on secondary axis

Is there a way I run this script?

I have a large dataset that I intend generating a sample of 10% from it to run my machine learning model 20 times. To test how it will work, I decided to use iris dataset to try it. First, I split the dataset into training and testing dataset and then used a While loop to… Read More Is there a way I run this script?

Why is my summary in R only including some of my variables?

I am trying to see if there is a relationship between number of bat calls and the time of pup rearing season. The pup variable has three categories: "Pre", "Middle", and "Post". When I ask for the summary, it only included the p-values for Pre and Post pup production. I created a sample data set… Read More Why is my summary in R only including some of my variables?
