Subject: Aligning barplot
All, Consider:
BagA <- c(-1000,10,10,10,10,10,10,
10,20,20,20,20,20,20,30,
30,40,40,50,60)
BagB <- c(10,20,30,30,40,40,50,50,
50,50,50,50,60,60,60,60,
60,60,60,1000)
layout(c(2,1))
barplot(table(BagB))
barplot(table(BagA))
At this point, I'd like to arrange the plots so that the 10-bars are
aligned, the 20-bars are aligned, etc. So, I started thinking, how do I add
an entry to a table? I tried:
tmp <- table(BagA)
tmp[8] <- 0
names(tmp)[8] <- "1000"
barplot(tmp)
But I got this error:
> source('~/.active-rstudio-document')
Error in barplot.default(tmp) : 'height' must be a vector or a matrix
Makes me think I should not be telling my students to do:
barplot(table(BagA))
As it might give future troubles.
1. What am I missing?
2. Can anyone propose an alternate strategy for aligning by tables?
Thanks
