The only Hungarian R User Group so far, the Budapest Users of R Network, with already more than 100 members, is hosting two talks on the 27th of November on DataKind and the tm package.

Bence Arató, head of a BI consulting company and the program chair of several Hungarian conferences, will give a short talk on the data-related problems of nonprofit organizations and how professional data analyst could help there.

Then Zoltán Varjú, computational linguist working at Precognox,  will talk about the theory of text mining and present a real-life use case (probably with Twitter data) of what could be done with R and the tm package in 30 mins or so.

Please find below a promo image made by me, who has nothing to do with text-mining, but I suppose we will see something like the below image (FIXME). Here I fetched and tabulated the dependencies of all the CRAN packages to be visualized on a (log-scaled) word-cloud in the colours of the Hungarian flag:

## compile a list of available packages on CRAN
aps   <-
## get the list of Depends and clean up a bit
deps  <- gdata::trim(unlist(strsplit(as.character(aps$Depends), ',')))
deps  <- gsub('[ \\(].*|\\n', '', deps)
## freq table
depst <- table(deps)
## plot it!
wordcloud(names(depst), log(as.numeric(depst)), colors = c('green', 'red'))

Resulting in:
