What is the best way to produce a barplot from my data? I would like
the barplot to show each person with the values stacked
val1+val2+val3, so there is one bar for each person When I use
barplot(data.matrix(realdata)), it shows one bar for each value
instead.
To post here, I created an artificical data set, but it works fine.
fakedata <- as.data.frame(list(LETTERS[1:3]))
colnames(fakedata) <- 'people'
fakedata['val1'] = abs(rnorm(3))
fakedata['val2'] = abs(rnorm(3))
fakedata['val3'] = abs(rnorm(3))
barplot(data.matrix(fakedata))
At a glance there is no substantial difference is between my fake data
and my real data.
person val1 val2 val3
1 A 221 71 175
2 B 222 85 147
people val1 val2 val3
1 A 0.75526748 0.445386 0.09186245
2 B 0.06107566 2.008815 2.50269410
3 C 0.47171611 0.592037 0.57612168
However
person val1 val2 val3
1 NA 221 71 175
2 NA 222 85 147

2: NAs introduced by coercion
So then I converted 'person' from a list to factors, which removed the
coercision error, but barplot() still shows each bar as value instead
of a person.
My serialized() data subset is here (look at bottom half where there
are no line numbers)
