installing on arch and gentoo is hard (arch user gave up installing Rstudio and used command line; gentoo user had to use VNC!). Installing on Ubuntu was hard too.

When specifically asking people for verbal feedback the general responses were that it was helpful, friendly, nice format. Many people wanted more (quite a few without prompting asked if it was running next week at the same time). When specifically asked what did people want more of the responses were: more R (twice); pandas; iceberg; SPSS; bring-our-own-data.

Q: What are integers shown when do
str(dataset$someFactor? A: when a categorical variable is encoded as a factor then each of the valid values that the factor can take is mapped to an integer and only this integer is stored per observation (partly for efficiency reasons).We should revisit factors in a later session and aim to cover things like setting factor levels, factor ordering and converting factors to numeric or character vectors.
