7:Creating reproducible reports in R
This is very important for R code integration and reports. We want to share our reports with Classfellows, collaborators or instructors.
Then, the R Markdown file can help us to recognise and compile the basic components of reports.
Create the R Markdown file to submit your results in PDF, Word, or HTML using Knit.
