## Kaplan-Meier Survival Curves In R With ggplot2

by | May 19, 2017

Hi there. I have been self-learning/reviewing some statistics and R topics as of late. Through experimentation and trial and error, I have made Kaplan-Meier survival curves in R with the ggplot2 package. Kaplan-Meier survival curve plots are used to model time to event data between groups. In one of the plots generated in R (see… Read more »

## Producing Correlation Plots In R

by | May 12, 2017

Hi. I have made a recent page on producing correlation plots in the statistical programming language R. You can find the page here. Through trial and error I have used the packages ggplot2 and corrplot to create various correlation plots. Correlation measures are used to assessing the relationship and strengths between two variables. One example… Read more »
