Hi there. I have made a recent page where I work with plotting random walks in the statistical programming language R. The page can be found here. Another related page is a detailed page on the random walk. The featured image is from https://www.r-bloggers.com/wp-content/uploads/2010/12/cointoss.png.
Hi. I have been doing some work with strings in R and needed some understanding of regular expressions in order for replacing/removing certain characters in strings. This page is a good resource for understanding regular expressions in R. Just thought I’d share this to those who are interested. The featured image is from https://www.r-project.org/Rlogo.png.
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 »
Hi. I have been taking this online quiz which tests your skills and knowledge in the statistical programming language R. Trivia and memorization is not my strong suit so this quiz does help with memory and problem solving. I have learned a few new things on R from the quiz. This quiz can be found… Read more »
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 »
Hi there. I have made a recent page about me playing around with the melt() function from the reshape2() package in R. This melt() function is a neat tool in converting wide formatted data into long formatted data. This long formatted data in R can be used for data analysis and for plotting. The page… Read more »
Hi there. A while back I analyzed a babynames dataset on the most popular babynames using R’s data.table package. The page can be found here. In part two, I analyze this same babynames dataset but with a graphical approach. I created sideways bar graphs with the most popular babyname on the top. I ended up… Read more »
