Let's get started with R (beginner's workshop)

This meeting is full (over full, actually), so if you can, please sign up for the alternate time (February 8 at 1:00pm at the Leawood Pioneer Library).

Bring your laptop! We'll start with showing you how to get R and RStudio installed on your computer. Then we'll show you how to read data into R and write it out again. Finally, we'll get you to run some simple descriptive statistics. 

This meeting will last 90 minutes.

    After R is installed at the meeting today, I'll discuss Reading and Writing Data in R. This page shows the notes I'll discuss: http://earlglynn.github.io/R/in...­. In particular, the sections: writeLines/readLines, read.csv/write.csv, and Reading Excel files. There are several other R I/O topics listed on that page that I'd be happy to discuss if there are questions.

  • Mary G.

    I had originally signed up for the Jan 18th meeting. I've now signed up for the Feb 8th meeting to help with crowding. My name is probably still listed for the 1/18 meeting - because I don't know how to "un-sign-up"! :)

  • Bob W.

    The attendance list is still sitting at 20. I'm unavailable on the 8th otherwise I'd wait until then. Just to reiterate, if you can go to the second session please do. I'm getting the feeling that there won't be space for people to put their laptop down on a table or we'll have people trying to work on the floor.

    Don't forget that we have an alternate date for this beginner's workshop (February 8, 1:00pm-2:30pm, Leawood Pioneer Library). Sign up for that talk if you can, instead of this one, because we will be very crowded on Saturday.

    All of my material for Saturday's talk is now available. Go to http://blog.pmean.com/beginners...­

    and download the appropriate files to your computer prior to the talk, if you can. Also, if you are adventurous, please feel free to install R prior to the meeting. It will save you (and us) a bit of time. If you have trouble installing R or just want a helping hand, that's okay. We'll be glad to look over your shoulder at the start of the meeting and make sure you get things done right.

    The R Studio and R Commander files are very nice to have, but not strictly required. We'll also put the key files on a USB flash drive and have that available at the talk, just in case you have problems with the Internet connection at the meeting.

  • Earl F G.

    I'm putting some pages online about read and writing files in R for the meeting on Saturday. Here are some draft notes about writeLines/readLines, http://earlglynn.github.io/R/in...­. Here are some notes about read.csv/write.csv, http://earlglynn.github.io/R/in...­. I'm hoping to also get some notes written about reading data directly from an Excel file. Give me feedback about these notes. Suggest additional future I/O topics. I list a few other topics here: http://earlglynn.github.io/R/in...­

    Two more things.

    I'm looking at a variety of locations for future meetings, assuming that the interest in R continues. Myles Gartland has offered meeting space at Rockhurst University and that may be a nice long term solution. Madelaine's suggestion about Cedar Roe Library did not work out, but that led to finding out about the Leawood Pioneer library. I'm very interested in any other suggestions for meeting spaces.

    Second, I'd like suggestions either on this message board or at the meeting on future topics for beginner's workshops. We definitely want to talk about graphics in R and about R Commander but there are others. I'll take suggestions from beginners, of course, but if you're a seasoned R user, your suggestions are also welcome. And if you can suggest a topic and can teach it too, I'll come to your house and clean all your toilets.

    I've been looking around and cannot find any good alternatives just yet for the January 18 meeting. But a very nice meeting room fell into my lap on February 8 from 1:00pm to 2:30pm. It is at the Leawood Pioneer Library near the Town Center Plaza. It can hold 50 people. So I'd like to repeat the beginner's workshop on that date at that location. I've checked already with Earl so we've got two out of three speakers. Caleb, can you make the February 8 meeting and would you mind repeating your talk about installing R?

    Note that this starts at 1pm and not 2pm!!!

    If you are currently registered for this beginners workshop and can attend on February 8 instead, please unRSVP here and RSVP for that meeting. We really would be crowded on January 18 and I'm still willing to try to make this work. But I suspect that we would be sardines on January 18.

  • Bob W.

    I'd like some one to talk about how to efficiently organize an R project. Like, code files here, data files here, etc. Like how MS has project folders and certain files go certain places.

    January 13

    • Steve S.

      That certainly sounds like an interesting topic and we should see about talking about it at one of our regular meetings (as opposed to a beginner's workshop). Another closely related topic is the use of sweave and/or knitr to create reproducible data analyses.

      January 13

    • Steve S.

      Our next regular meeting is scheduled for March 1, and we already have a couple of topics scheduled (wavelets and shiny). If someone is willing to tackle rstudio, I'd be glad to add it to the agenda of the March 2 meeting.

      January 13

  • Steve S.

    I thought of a couple of things we might want to add to the agenda. First, how to use the help system within R. Second, data frames and factors in R. We don't have to go through all the different data types in R (e.g., lists), but when you import data in R, you need to import into a data frame, so we need to define that. We also need to explain what a factor is because you have the option of importing character data as a factor or not as a factor when you import using read.table or read.csv.

    January 13

    • Earl F G.

      Steve: As part of the R I/O talk, I planned to show 3 or 4 versions of read.csv to show how that can affect data. In the context of a data.frame created from read.csv, I planned to briefly discuss types: integer, factor, numeric, character and Date. Would that work for you?

      January 13

  • Madelaine

    I'll try to attend to help walk around and answer questions / help individually. One option to look into for future meetings is Cedar Roe library meeting room. No nice online booking abilities, but it would hold more people and I think they have a projector available.

    January 7

    • Madelaine

      Oh, I guess you can book online, but not check availability.

      January 7

  • Myles G.

    Steve. Want to have it on our campus? I can easily get a room for 30 or more that already has a projector and wifi. Just an offer if you need it. Myles.

    1 · January 7

  • Steve S.

    I've bumped the attendance limit up to 20.

    We'll be standing room only at this meeting! We can't move to the large meeting room as it is already booked by some other group. We might think about repeating this offering (assuming that the speakers are willing) on a separate date. For now, let's just all cram in together.

    Thanks, Dan, for bringing a projector. We'll need it!

    January 7

  • Monica G.

    Please increase the numbers. I am on the waitlist. :(

    January 7

  • Dan W.

    FYI, I'll bring a projector.

    January 7

  • Steve S.

    At the last 10 minutes of this meeting, I'd like to discuss what topics you'd like to see in future beginner's workshops. We definitely want to cover simple graphics (like boxplots and scatterplots). Bring your ideas to this meeting or offer suggestions here.

    January 7

  • Steve S.

    All our meetings last 90 minutes. I thought I put that information in, but apparently it is not displayed. I just still learning how to use meetup.

    How long do you anticipate this meeting being?

I decided to start Reno Motorcycle Riders Group because I wanted to be part of a group of people who enjoyed my passion... I was excited and nervous. Our group has grown by leaps and bounds. I never thought it would be this big.
