I'm working with questionnaire survey data which has multiple choice questions - all categorical (e.g. What beverages do you consume - tea, coffee, something else etc.). Responses from each respondent is currently stored as a list - e.g. Respondent 1 - list(tea, coffee, something1), Respondent 2 - list(tea, something2) etc.
Can anyone recommend a good package to handle such Multiple Response Categorical Variables to make them easier for analyses - to summarise, carry out univariate/multivariate analyses and so on? I found the MRCV package (https://journal.r-project.org/archive/2014/RJ-2014-014/RJ-2014-014.pdf) which looks useful, but it doesn't specifically address how to prepare such data for further analyses. Are there any existing R packages which help with this, or will you have to manually organise the data for analyses?
Thanks
