I will give you two ideas that would possibly help for the two problems you mention. First, I create some pattern information:

set.seed(175) alternatives <- c("A", "B", "C", "A,B", "A,C", "B,C", "A,B,C") data <- information.frame(respondent = 1:15, letter = pattern(choices, 15, replace = TRUE)) knowledge ## respondent letter ## 1 1 A,C ## 2 2 B,C ## 3 3 A,B ## 4 4 C ## 5 5 B,C ## 6 6 A,B ## 7 7 B ## 8 8 A ## 9 9 B,C ## 10 10 C ## 11 11 A ## 12 12 B ## 13 13 C ## 14 14 A,C ## 15 15 A,B,C

For simplicity, I used only three ranges.

1) The following serve as can be used to plan `information$letter) directly in the method you need:

plot_allapply <- function(possible choices) # convert to persona choices <- as.personality(alternatives) # break up at comma and unlist choices_split <- unlist(strsplit(possible choices, ",")) # convert back to issue and plot plot(as.issue(choices_split)) plot_allapply(information$letter)

It works as follows: First, the knowledge in letter needs to be transformed from type factor to character. (I know that this is a factor, because differently you would not get a plot at all.) Then, each element of the persona vector is split at the commas. (Run strsplit(as.character(data$letter), ",") to look how this works on your data and ?strsplit for more information.). Since this yields a listing, it's converted to a character vector the usage of unlist. The ultimate line converts again to issue (which is wanted to ensure that plot to create the proper of plot) and plotted.

2) There are some ways how you should paintings with the knowledge in data$letter. If you are interested to know, which respondents selected "B", it's essential do

grepl("B", data$letter)

This will go back a logical vector that is TRUE on every occasion "B" is contained in a respondents answer. Thus, all of those will give TRUE: "B", "A,B", "A,B,C".

Maybe it helps so as to add this information on your knowledge frame. This may well be finished as follows:

knowledge <- turn out to be(knowledge, isA = grepl("A", letter), isB = grepl("B", letter), isC = grepl("C", letter)) data ## respondent letter isA isB isC ## 1 1 A,C TRUE FALSE TRUE ## 2 2 B,C FALSE TRUE TRUE ## 3 3 A,B TRUE TRUE FALSE ## 4 4 C FALSE FALSE TRUE ## 5 5 B,C FALSE TRUE TRUE ## 6 6 A,B TRUE TRUE FALSE ## 7 7 B FALSE TRUE FALSE ## 8 8 A TRUE FALSE FALSE ## 9 9 B,C FALSE TRUE TRUE ## 10 10 C FALSE FALSE TRUE ## 11 11 A TRUE FALSE FALSE ## 12 12 B FALSE TRUE FALSE ## 13 13 C FALSE FALSE TRUE ## 14 14 A,C TRUE FALSE TRUE ## 15 15 A,B,C TRUE TRUE TRUE
