Plotting participants within a pair on individual axis' in R? -

i have data experiment, participants have been working in pairs, , have rate enjoyment after task.

participant<-(c(1:20))   pair<-(c(1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10))   position<-(c(1:2))   enjoyment<-(c(2,6,8,4,5,6,2,3,9,8,6,5,3,2,6,6,6,7,8,8))   data<-data.frame(participant, pair, position, enjoyment) 

i plot each participant enjoyment score, have each participant within pair on different axis (position 1 enjoyment on x-axis , position 2 enjoyment on y-axis).

any suggestions how might that?

follow pro's: how plot highest score within pair on y-axis?

thank you.

i don't have enough privileges comments, here goes:

i don't understand means:

(position 1 enjoyment on x-axis , position 2 enjoyment on y-axis)

wouldn't need 2 dimensions regardless? one-axis solution dots along axis line, seems. if clarify in question (perhaps visual aid), more helpful.

as code attempting answer question:

plot(pair ~ enjoyment) 

would position pairs on y-axis , enjoyment on x-axis, see difference between enjoyments (or in case 1 dot present, fact enjoyment similar).

if want add type of labels in order make clearer (with base r):

plot(pair ~ enjoyment, ylab="pair", xlab="enjoyment") text(enjoyment, pair, labels=position,pos=3) 

if find overlapping labels unpalatable (as pairs 8 , 10 in example), here thread dealt with.

is not asked for, , instead mean more complicated, package 'scatterplot3d' give more closely resembles description, given fact lengths of variables differ (position, pair , enjoyment), have kind of transformation.
