R Open Lab – Writing Loops
The topic for today is writing loops in R. Looping is equivalent to iterating or just replicating instructions. By letting the computer take over the repetitive work, we make our life much easier. We also talked a bit about how to avoid writing loops and make our code more efficient. Thank you to everyone who […]
R Open Lab – dplyr package
This Wednesday we talked about how to use the dplyr package in R. The dplyr package makes data manipulation faster, easier and more straightforward. We covered the syntax and functions of the package, and tried it out on our Walmart Store Sales dataset. We also briefly introduced R Notebook and R presentation. R open lab […]
R Open Labs – Writing Functions
This Wednesday we talked about how to wrie functions in R. The topic is very simple but useful. Thank you to everyone who showed up! See you next Wednesday 11/16/2016 10:00-12:00 at DSSC! Also, we will host a R workshop about regresssion next Friday 11/19/2016 10:00-11:00 at Science & Engineering LIbrary! […]
R Open Labs – Time Series Analysis (contd)
This Wednesday we continued to talk about some broad ideas of time series analysis. We explored seasonal trend decomposition, which can be used to show the seasonal fluctuation and main trend of the dataset. It’s a very involved topic, so thank you and a round of applause to everyone who showed up today. Next week […]
R Open Labs – Time Series Analysis
This Wednesday we talked about time series analysis. It is a very complex and involved topic, but most participants showed great interest, so we would continue talking about this for the next few sessions. Thank you to everyone who showed up! See you next Wednesday 11/02/2016 10:00-12:00 at DSSC! […]
R Open Labs – Data Manipulation
Today we introduced merge(), factor() and some basic techniques for handling missing values during the first 30 minutes of the open lab. For the rest of the open lab, there were free discussions about personal projects the participants are working on. We also introduced package swirl. Swirl package teaches you R programming interactively. Thank you to everyone who […]
R Open Labs – Plotting
Yesterday we briefly talked about how to do plotting in R. We mainly discussed plot(), barplot(), hist() and Lattice package. Thank you to everyone who showed up and we will explore more data visualization techniques for next session. Also, from next session on, the open lab will be much less structured and will involve more […]
R Open Labs – Basic Syntax
Hi all, last Wednesday we kicked off the first session of R Open Lab in the DSSC( based in Lehman Library). We started with basic syntax and briefly discussed how to explore the features of our datasets. We used data from Wal-Mart and we will continue exploring this dataset for the next few sessions. Beginners are welcome […]
R Open Labs: mi
Last week, Professor Ben Goodrich stopped by R Open Labs to show us how to use the mi package, which he worked on with Professor Andrew Gelman. As the name ‘mi’ suggests, this package does multiple imputations to help you predict missing values in your data sets. Check out the demo if you’d like to […]
