Histograms in R: How to Create and Modify Histograms with R

►In this R video tutorial, we will learn how to produce histograms in R and add a density curve to the plot using the "hist" and "lines" functions. We will also explain how to modify the histogram by adding titles, changing axes labels, changing the line colour or width and many more by using "main", "xlab", "xlim", "col", "lwd" arguments and more .

Dear Mike,
Your tutorial is absolutely amazing and easy to comprehend.
Thank you for those beneficial videos.
However, do you have any tutorials about time-series regression in R?

[MrKocharrohit]

I have watched all your R videos till this one and I loved them all. I work as a data analyst so I was wondering if you have a video where you analyse data by connecting R to SQL Server or Oracle?

Hi Mike, how are you?  I have a question about the LOGIT function.  How do you using?  The syntax.  I trying to answer a question with the information give - The logit transformation is often useful for the proportion between 0 and 1.  If p is the proportion then the logit is log[p/(1-p)]  This is the log of the ratio of the amount of pollen removed to the amount not removed.

Hi, I am trying to do a Hist as well but I seem to encounter an issue that states "Error in hist.default(HW9Data) : 'x' must be numeric" not sure what I need to do. I also tested it on the data you have for lung capacity, "> hist(LungCapData)
Error in hist.default(LungCapData) : 'x' must be numeric"
