Dear useRs!

Welcome to the fourth R useR group MeetUp in the larger Stockholm area.

The next session will be on Text analytics and R.

If you want to talk about something (possibly at least remotely related to text analytics), like a project you're working on, a library/framework/tool or something else - contact the event hosts and we'll add it to the agenda.

There are no experience requirements whatsoever, so don't hesitate to attend even if you're just curious about R.

Proposed agenda

18:00 - 18:30: Mingle and "fika" at cost price (20 SEK).

18:30 - 20:30: Intro + Talks + Breaks

  • Text analytics and R by Marina Santini

  • Wordclouds from Twitter with R by Måns Magnusson

  • An example of text analytics in R by Joakim Lundborg

20:30 - : After-meetup-beer at Tjoget/Linje tio (http://tjoget.com/)

    Given the hosting locale, were you thinking about a seminar on R in financial engineering? David Ruppert's Springer monograph seems a good starting point, but it would be interesting to hear from practitioners! kind regards, Lukasz

      Hi Lukasz,
      That's a really interesting idea!

      This would be a great topic of the first meetup in the fall of 2013 - I would suggest not to arrange it earlier (i.e. this May) since it would probably take a bit more preparations than our usual meetups. What do you think? Would you be interested in holding a short introductory talk on Ruppert's monograph?

    I had trouble with Swedish characters, even when my setlocale was right, but only if I was sourcing a file. I corrected it using source("MyScript.r",local=TRUE,encoding="native.enc")

    Thanks Serdar & Maria!
    system("defaults write org.R-project.R force.LANG sv_SE.UTF-8")
    works for RStudio, although don't know why Sys.setlocale doesn't work. One can choose between UTF-8 and Windows 1252 in the place that Maria suggested.

    Try to change the encoding in Rstudio. You can change the encoding in Options-General. If there is a problem with a single script you can try file - Re-open with encoding. Good luck!

    I dont use RStudio but Sys.setlocale("LC_CTYPE", "sv_SE") works for me when I produce graphs

    Anyone got idea how to enable åäö in RStudio coding?
    My sys.getlocale() shows correct Swedish settings:
    Try to append LANGUAGE=se in shortcut - properties - target, but not validdated!
